So stoked to get one of these bad boys. Built my truck on the website and gonna be sending that in to the dealer soon to order for me. Gonna be my first ever new truck!
As an OTR truck driver for many years since 2008 and the beginning of the DPF era I am very familiar with these systems. Many times to reduce the problems associated with soot accumulation the manufacturer will program the ECM to regen at set mileage intervals so that the DPF remains as clean as possible. They do this so if the motor fails to regen when necessary it will do it anyway just in case. I think you are observing this now. If you are interested I would like to explain how using a fuel borne catalyst may greatly reduce your regen frequency and duration.
Keep going with the videos, Chad, they're awesome! I want to get a 3.0L Duramax like yours, but I want the standard bed with a crew cab... so it's going to be a while until I can find one.
@@eric-ik7kv I talked to a salesman 3 days ago and he said it'd be a $1000 down payment to do that, but obviously that's to actually order the pickup. He didn't seem interested in letting me spec one
Dealerships can be a pain. If you are interested in traveling a little bit, Brian Miller at Alserra would hook you up with the truck you really want, they order customer specific units all the time. You could call +1 800-494-3814 or e-mail him at bmiller@alserra.com. Let me know how it goes.
I was in Lubbock TX last week and they happened to have 1 on the lot and I got it. Drove back to Houston and averaged 29 mpg. This is an amazing truck. In my opinion this is not a truck for towing. This is a truck for people who drive tons of miles and want a full size truck and don’t want to get 15mpg. Mine is a crew cab short bed z71 LT.
This is REALLY good mpg for a full size truck. My BMW diesel car (335d) has the same size 3.0L inline 6cyl with twin turbos and gets about 36mpg at 80mph cruising. The torque and power is amazing, with just tuning and intake/exhaust putting down 365whp/595tq.
Even houses down there are way too expensive I’ve seen 3 bedroom houses in La go for $500k. Up here in Virginia I can buy that 80k and a big ass 5 bedroom house with a shit ton of land for $500k
@@smitty554 not one thing I'm averaging 21 low to 26.5 mpg city mine Is fully loaded though. if you have anymore questions just ask. andy.smith.5252002@gmail.com
The last time I was on that stretch of highway, I and everybody else were going 90 mph, it was a Sunday afternoon, I wish that we could travel that speed all the time.
Yep, it's a good stretch to not have to pass anyone at 70mph. Sunday afternoon is a lot of people running for the border :). Thanks for watching and commenting.
This is incredible. 31MPG highway going 70mph on a full size pickup with a regen in the middle. What if you slowed down to 55mph? It could go up to 35MPG?
I haven't seen above 32 with mine, yet. I had a fellow owner tell me he saw 43 on a multi-state trip. I'm getting 10-14 towing, with around 13 being my average.
Very good work Guy. That's really impressive fuel economy for a half ton truck ! Really appreciate the level of detail . Be safe out there and enjoy that new truck !
@@EfraKrajo That is correct. If you tow a light to medium load the temp actually goes down. This engine has a very sophisticated cooling system that can route coolant to where it is needed most.
Jeff, I just finished a long road trip to Harrisburg, PA then to Austin, TX and back to Michigan, overall it was more than 4,000 miles towing my 7x16x7.5 enclosed trailer. Doing the speed limit on all the highways I averages 13.8 mpg. Gross combined weight was 14,000lbs, not max but pretty close, 15k is the limit set by GM. Funny part was with the trailer full or empty the mileage didn't change. Vehicle speed and wind makes the most different in overall economy. I'm back into my towing season again so I have been trying several different things, I'll have a video ready in the not too distant future :)
great video! If you are able to get your hands on a 2019&up 5.3 or 6.2 v8 to run the same loop it would be interesting to see the real world difference as im sure many viewers are cross shopping the 3.0 duramax with its gas v8 counterparts
I talked to Alserra and it seems like I'll be able to get my hands on a few different configurations, dealer demo trucks. There are so many configurations, 5.3 8-speed, 5.3 10-speed, 6.2 10-speed and 2.7 8-speed. I can do the 5.3 8-speed and 2.7 8-speed pretty quickly if they are interesting. Let me know if that would be good.
Chad Ivan I personally am interested in the 5.3 10spd and 5.3 8spd same body config as your truck crew cab. i didn’t realize the 8spd was still going to be offered i figured it was phased out by 10spd.
After seeing this it turned out to be almost exactly the same as my 2021 Chev 3 liter turbo 4x4 after a 154 mile run, but in Canada giving me 37.12 miles per Canadian (Imperial) gallon which is about 1.2 times bigger than a US gallon. Also set at 120 kph (75 mph) and staying in the center lane of 3 lanes and land elevation conditions were also pretty close to the same. From my perspective if this engine holds up, it will be a classic as the low to mid-range torque and fuel milage is phenomenal.
I really appreciate your videos Chad. Informative, concise and applicable. I've been looking forward to the 3.0 duramax for a while and your videos are giving me real world info I can't find elsewhere. Do you plan to shoot a towing video with MPG numbers any time soon?
I like the video, can you do a video driving the same loop with a 5.3, 6.2 and 3.0 to give a full perspective on which one is better overall to buy between cost of the truck fuel consumption maintenance etc.
I do have a fuelly account that I track every mile but the overall average is low do to the amount of towing I do with the truck, I would say I'm at about 45% with a trailer on the back. Take a look at www.fuelly.com and look for 2020 Silverado, last time I checked there are only 2 on there.
Problem with that is if he does any towing the overall mpg drops like crazy. With my Colorado Diesel the mileage I get is fantastic but over the long term doesn’t look that good, because I tow a lot.
AuctionAdOnline My 19 Super Duty diesel is the same. 17-18 mpg highway unloaded and once I put 8000 lbs or so trailer, it’s 13 mpg. But I consider that fine because the two together weigh 16,000 lbs. Moving 16,000 lbs 13 miles at highway speeds, comfortably, on a gallon of diesel is a-ok in my book!
@@watchmanexpert it is theoretical possible to send the command via that interface but I don't know the command and it's not built into Torque Pro. You can do it via the Banks iDash unit, the 2020 through 2022 with the original interior, the new interior has a different interface and Banks has not updated the iDash for that feature as of today. I hope this helps a little bit.
Diesel fuel in US does not meet specifications for diesel in terms of lubricity. That's a reason for diesel engines to have bad reputation for injection systems to fail. Thanks to diesel fuel additives, diesel injection systems reliability can be improved. Thanks for sharing. Very good fuel economy, keep posting your videos about this truck.
Thanks for the information and I'll keep them coming. I can say that I put ~95,000 miles on my Cruze with the 2.0 diesel and didn't have any problems with the pump or the injectors. I'm working on one about "Running out of DEF", spoiler, turns out you can't :) Gotta love the EPA
@@CJIEngineering , your 2.0 didn't have problems with injection systems, it has different high pressure pump. Older duramax engines with cp3 didn't have as many problems with injection systems as much as cp4 has been.
Thank you, I'm thinking in the not to distant future you will be able to get this engine in some of the lower content models like they did with the 2.7l Turbo for 2020...
I am considering a 3.0 for my next truck I do a lot of camping and I would like to see the loop done with your cougar camper attached a regen in the run and if you can swing it scale the whole setup.
I can do everything on your list except the Regen. The truck will more than likely stay in passive Regen the entire run. Please stay tuned, hopefully I can do it in the next week or two.
No charging issues. I believe the system is smart, charges up and then lowers the charge rate to float the battery/save fuel. I did drain the battery low but that was because I left a light on in one of my trailers and the truck isn't able to power down the 7 pin plug :(.
Do you have any plans of getting a tuner for the truck or even deleting it? Also I’m not sure where you’re located but can we get a cold start when it’s a real cold day? Thanks subbed keep making great vids!
So I own an EFI Live unit, mostly to understand how the engine is really working. They don't have support for the 3.0 Duramax yet but I'm pretty sure if it is a popular choice they will add it in the future. I don't plan on deleting it because I want to see if you follow the manufacturers recommendations, maybe changing the oil a little early based on the analysis, will the system work for a long time. My Cruze Diesel has almost 93,000 miles on it and the DEF heater went out once and one NOx sensor died, both are covered under and extended warranty so no cost out of pocket. Sorry to ramble on... I will be doing a cold start for sure in January or February :). More videos are on the way including the towing mpg loop.
I see you might have or have had in the past diesel equinox and Cruze. My wife has the diesel 1.6L equinox and it’s awesome. Outstanding mpg. Maybe you can showcase the the other vehicles you have.
Chad, thank you for the video. I'm interested on buying a truck with a 3.0, baby duramax. this helped me make up my mind. now its between a silverado or GMC Sierra AT4. As far as the videos, i would recommend a litlle more editing.
If I were to do it again I would buy the GMC AT4. The one feature that is missing from my truck is the unlock buttons on the rear doors, really a pain in the butt to click the front door button twice instead of clicking the rear door button to unlock all the doors. A little thing but something I wish my truck had on it pretty much every day....
Is that a 6.7’ bed? Do you mind sharing what you paid for the truck and what incentives were used? I’m looking to order one built because I want tow mirrors and I can’t find any out there already built with them.
I'll see what I can do. The last few Regens have been between 175 and 235 miles, a little more often than I would like but I'm hoping it gets better as the engine seals up.
Really good helpful info here, thanks for keeping your videos info rich. I would also like to see the same loop w/o the regen; but I would add an interest in towing numbers as well. In general, I'm wondering if you could do a detailed segment on MPGs will towing in various terrain, loads, weather, etc. Also, towing impact on regen frequency. Lastly, do you know if Chevy makes a 6 seater? I've got four kids!
Thanks for the questions and suggestions. I am going to do the tow test in a few days, 70mph with the camper and 103 miles to have that data. I can say for certain that while towing the regen frequency is lower. I did a few trips towing and I was able to go over 600 miles, the truck towing a decent load will do a passive Regen, exhaust temperatures are high enough to keep it burning :).. I understand that there should be a couple of 2021 large SUV with 3 rows that will have this engine installed in it :)
Chad Ivan I have the 3L in my gmc,manual says regen every 500 to 700 miles mine regens every 175 miles hopefully it gets better then every 175-200 miles. Have u heard if it will get better than 175 miles?
While you were holding 70mph steady and abut 1500rpm, I was surprised to see the oil pressure fluctuate from somewhere near 30 to 40 psi. Why would that be? and is that normal for all engines or just diesel engines? Thanks.
Thanks for the question, the engine has a variable displacement oil pump so based on load the pressure will change. As the truck was going up small hills the pressure would go up to 40 psi and under lighter loads it stays around 30 psi. Towing it gets close to 60 psi.
Man n I just bought the 2500hd. Should have explored my options that truck seems like it will last a long time. Hows the pull when going up hills? Does it search gears alot or just go?
Congratulations on your 2500hd. The truck does really good going up the hills I have done in Michigan, I not taken it into the mountains yet but I has done great so far. Absolutely no hunting at all, just grabs the right gear and lugs right up hill. If you use the cruise control it will do a great job of keeping you at you set speed +/- 2mph. The engine has an exaust brake and it works pretty well. Thanks for the question and check out my other videos for more info.
Have you towed anything weighing near the 9000lb towing capacity yet? I'm curious if they lowered the number to downplay expectations or if the limit is too high.
I have towed very close to the max GCWR. The engine/transmission has capacity left but I'm not sure about the cooling system or the suspension. I'm always towing in temperate areas, never in the desert so I won't ever find out. I personally would love to see GM have a heavy 1/2 Ton with this engine/transmission, a mechanical cooling fan, and a little more load carrying capacity. Towing videos are on the way.
@@reginaldsmall3766 it uses 0w20 Dexos D oil. This is a new oil specification specific for the 3.0l inline 6 and I believe it is also used in the 2.0l inline 4 used in Europe with the Cadillac XT4. I'm only able to buy it from GM, AcDelco branded, Mobile oil. It lists for about $8.00 a quart but I have been able to buy a box of 6 for Around $36.00, not too bad... Thanks for the question.
Well one minor issue that I have is that I'm having a regen every 150-250miles so it's hard to get over there and run the 103miles without one :(. I'm going to be taking the truck in for the seatbelt recall in a week or two and have them look at the regen cycle data just to get it documented. My other diesels do the regen every 450-800miles on the same pumps fuel so I'm not sure if it still need to seal up or not. I'll see what I can do. Thank for watching and commenting. Stay tuned :)
Hi Chad, New comer to your videos. Have you towed any with your Silverado/3L Duramax? I’m curious about a couple things, how often it regen’s for mixed driving, and how it handles a modest-medium sized TT (5-6K) in terms of fuel economy, cooling system and oil temps, and regen frequency. I’ve noted that some of the small diesels run VERY HOT when towing anything with a significant ‘brick effect’ like a travel trailer. I may be looking for a nice eco / light towing truck and am trying to get a good sense of which manufacturer has done their homework for cooling and gearing best so my truck won’t be overtaxed or running super hot while towing. Many thanks for info on your experiences!!
I have towed about 45% of the first 4,500 miles including a couple of times very close to the max GCWR. I'm going to do the same mpg loop in the next few weeks with my Cougar 27res that weighs in around 7,400 lbs. I'll make sure I talk about all of your questions.
I have a 0-60 video posted, 8.067 seconds. No turbo lag at all. My Colorado 2.8 Duramax had about 1 second of turbo lag due to the long distance from the turbo to the intake, this thing with the water cooled intercooler has about 1/10 the distance the air has to travel and compress. Thank for the question.
The price of the belt is $13.70 and you need to move the transmission/transfer case back and remove an access cover to get in and change it. A full transmission swap can be done in 4-5 hrs so I would expect this to be similar, maybe a little less. Not horrible, better than changing a timing belt, Power Stroke....
Thanks for this video, I just purchased my first 2022 3.0 LTD and am super happy with it so far. The MPG is amazing compared to my 5.3. If I may ask, what is the app you are using? Thanks again
Congrats on the new truck. I am using Torque Pro on my Android phone. If you take a look at my other videos I have one one it and I share the extra PIDs. I have DEF level and some other values that help you keep track of how the engine is performing. Keep me posted and let me know if you need more help.
Good review love those mileage numbers have you did a towing mileage review are did I miss it but this is a truck too look at thanks for your time doing this review keep them coming
I have not filmed a tow mpg test yet but it is on the short list. My plan is to do the same loop at 65mph to get some balanced and comparable data. Keep you eye out for it in the next few weeks.
How often is your DPF regen cycle? My 3.0l Duramax has 900 miles and is regenning every 150 miles or so. It seems very frequent to me. My 2016 LML would regen every 600 to 700 miles.
My truck is also doing a Regen every 150-250 miles under light load. Just took it to the dealership and had a ECM and Reactant Module updated. On January 3rd 2020 a new software was released, I'm hoping it will help some. Towing I have went over 600 miles but that's because it is passively doing the Regen all the time. The service department said that was normal with this engine but I wanted it documented anyway. Thanks for the commenting and watching. I'm going to post a video with my service info this weekend.
My drive to work is 17 miles one way on two lane roads with speed limit being 55. I have to stop 3 or 4 times during route. Do you think this would be enough distance for a regen and can you do a manual regen ?
I think it would be able to finish on that cycle. There is not a manual mode unless you are able to get a fleet model and I'm not sure it is really necessary. Thanks for the question.
What's the point of the better mpg when the price of diesel is so high compared to gasoline? I'd stick with the 5.3l or 6.2l if you need more towing capacity.
Part of the reason is the driving experience, I love to drive an engine that has lots of torque and runs at lower RPMs. It's what I like and I have had several other gasoline towing vehicles and I hate having to listen to a V8 sing at 4,000 rpms.
Great video, i would also like to see how higher speeds affect the mpg like PhillLsx GA mentioned. i have 87 mile commute to work one way 90% interstate and average 77 - 80 mph. I have seen in the past that vehicles are tuned to meet highest mpg at posted speeds and tend to fall off significantly at even several miles per hour higher. I currently have been trying to get one of these trucks for a day to verify but dealership doesn’t want to put 180 miles on truck that i may not purchase.
Andrew, there are several things to consider when it comes to mpg. First it the difference in wind resistance between 80mph and 70mph is a squared function so 80*80=6400 and 70*70=4900 so if the truck does not get more aerodynamic at higher speeds, and I don't know if these do, you are going to get 31*4900/6400=23.7mpg. This math holds true regardless of the engine that you pick you loose 25% running faster. The second thing to consider is the advantage that diesel engines offer. Most engine use the least fuel per horsepower at peak torque so at 70mph it is turning 1,575rpm so at 80mph it will be turning 1,800rpm in 10th grade. The 3.0 Duramax has peak torque available from 1,500-3,000rpm so it will be in an efficient operating range at either speed, this shouldn't negatively affect the mpg you will get. The Silverado does have larger air curtains than the GMC so there is a chance at higher speed it could be more aerodynamic???? I hope this helps a little and thanks for the question.
Chad Ivan thank you for pointing out the math on this. I am still interested in the objective test results and interstate highway is my preference. Always interesting to me to prove out the math.
I'll try to do another run at the higher speed after I get a few of the towing videos done. I also like to prove out the math and we could see if the truck does beat the math.
Finally got My 3.0 LTZ.. but disappointed with mpg. Only getting 20-21 on interstate with Midwest winter diesel. Only 550 miles on it. It was windy but hoping for around 25mpg minimum.
Chad Ivan I was running in 2wd normal mode using adaptive cruise at 76. My 50 best is 24.6 and average around 20. Haven’t checked the others. Like I said only 550 miles but seems low. It was windy this weekend going to IN this weekend.
I'm looking to buy a Chevy/GMC in November. I tow rarely and most of my driving is 55+ mph. I would like your thoughts about 3.0 vs the 5.3. Knowing what you know now, would you stay with the diesel or go with the 5.3. I'm looking at the diesel for the mpg and durability over the 5.3. Any idea of what your cost of ownership has been yet? Your video was nice for me as I'm in the same area.
Zorb, You question is a little hard to answer for me since I'm a little biased toward the 3.0 Duramax. Both the 3.0 and the 5.3 are technically new engines, the 3.0 started production in 2019 and the 5.3 DFM motor started in 2018. The 5.3 AFM motor has been being built for a lot of years and have had some oil burning issues and the ones that I have driven the switching between V4 and V8 mode was annoying both from a sound and smoothness perspective I would never own the 5.3 AFM motor. I have driven only 1 DFM motor and the transition between 8 cylinder and less, it can do 7, 6, 5, 4, 3, or 2 cylinder mode was almost undetectable so that was a plus. The 3.0 is so smooth and always stays in 6 cylinder mode and and inline 6 cylinder is one of the smoothest motor configurations possible. It does have a valve in the exhaust that will make it have a little bit of a drone under very light throttle conditions. Torque and overall drive-ability goes to the 3.0. The transmission on the 3.0 is the 10 speed, it is one of GMs best transmissions, the 5.3 can have either the 8 speed or the 10 speed depending on what model you get. Since you will be driving the truck at 55+ most of the time the next thing to consider is how long you drive it, more than 5 miles or less than 5 miles, a general cutoff for making sure the diesel particulate filter gets cleaned routinely. Since you have some time left before you make a purchase, please stay tuned to my channel and I'll be posting some more videos for new diesel owners including some cost of ownership info. Thanks for the question I hope this helps a little bit for now.
@@CJIEngineering Thanks Chad. Helpful information. My current daily commute is 32 miles each way. The last two trucks I've owned I've paid off early dumped the first (F150) at 143k miles, and the second (sierra SLE) looks like it will also be around 143k miles. I was going to keep this one until the wheels feel off, but after the dealership mechanic dropped chunks of the fiberglass filled plastic intake manifold gasket into both cylinder heads. The chunks melted and stuck to the exhaust valves. In short, I do not trust they removed all the fiberglass fibers from all the affected cylinders. Fiberglass is extremely abrasive. A $1000 repair (high pressure fuel pump) nearly cost me $5000. Fortunately my line of work and being a former mechanic allowed me to prove they were at fault. This will be my 2nd diesel, my first was a 2000 RAM 6.0 Cummings. Thanks again for the info. Looking forward to seeing what other videos you produce.
2021silverado 1/2 ton 3.0 L turbo babymax LTZ 2 wheel drive with 2500 miles on her .. houston texas . 34 mile one way to work (68 mile round trip ) 340 miles for 5 days . average 10 .5 to 11 gallons of fuel. ...slight tail wind my best on 25 mile setting was 41.3 MPG usually average about 35 on the dash.... hand figured city/highway combined about 31 MPG ... 60 to 70 mph depending on traffic....
With that kind of mileage I'm not sure why someone would ever buy a Hybrid Truck. Super mileage unloaded and really good mileage if you do tow. If you don't mind I'm curious what your 21's tow sticker says for both Max Trailer and 5th wheel. They changed the rating for 21 even thought the trucks didn't change, just tested there capabilities. Thanks for sharing.
William that is a little higher than our speed limit out here. I will probably be redoing the loop at 70 and 75mph because I have changed the tires to Goodyear Ultraterain and that took a little hit on my mileage but the have great traction. I could also do it during the winter when our fuel is a mix of #1 and #2 / lower BTUs compared to summer fuel.
I’ve been highly interested in these diesels including the 2.8 Duramax it’s the daily driving aspect that worries me. The emissions system works well during long distance, as with any modern diesel. I want one of these because I do tow just not everyday I don’t know if the emissions system will give my problems for short drives I don’t have enough distance for between my job and too much idling for warm up isn’t good either.
I have not had any real issues with either engine's emissions system. I did have the DEF freeze in the lines one time but after putting the truck in a warm garage for a night. My Equinox gets driving about 10 mile one way to work and it has been doing very well, no emissions system issues to date and it has just over 27k miles on it and we have had it for 2 years. One advantage diesel has over gasoline engines is that they don't really generate any water during combustion so a complete warm up is not to critical. I hope this helps a little bit..
Would love to see the mileage done at 75-80 as I think this is a more realistic highway speed for some in more rural areas? What is your rpm/egt at 80? Thanks!
Fuel mileage is impressive! Just wondering how it pulls that camper you have? I have a similar size and weight and pull that with a 5.3L and it does ok. What fuel mileage are you getting towing?
I will be doing a mpg loop in the next few weeks to have a good wind neutral value. Towing into some pretty strong headwinds I was getting 12.7mpg and another time 13.3mpg. Keep an eye out for an "official" test.
So what is your opinion of the 3.0 ltr and truck in general? I’m seriously considering this, moving from my 08 Chevy 2500 6.0 LTZ gas sucker to a lighter more efficient truck!! Of coarse, without compromising the torque!!
I have had an older 6.0l GM truck in the past and there is no comparison for the Torque that you have available. The key is going to be how many lbs you tow and if the frame on the 1500 is going to be strong enough. I routinely pull 5000 to 8000lbs and don't have any issues. I'm possibly going to put higher load rated tires on the truck just for the stiffer side walls. If you have never owned a modern diesel with all the emissions systems on it, watch my next view on the DEF system. No real issues but as a preview I'm having to fill up the DEF tank every ~1,500 miles while towing. No real issue for me but I have a 3,500 mile trip coming up soon and it will be interesting to see how that goes :) Thanks for the question and for watching.
I am very happy with the engine/transmission and the truck in general. No real issues with the engine only the recalls for some updates to software. They will already be done on and new truck. Mine is 4wd and I would highly recommend getting the Z71 package so you have low range. Reverse gear is pretty tall.
Chad Ivan Picked up a 2021 RST with the Duramax. Do you use any fuel additives that the owners manual states for people that can’t get top tier gas? Is the top tier gas critical. This is my first diesel truck.
@@doubles259 Well I just talked to a Top Tier Diesel representative and this is a awesome subject for a video I believe. The long and the short of it is that there are a super low number of stations that qualify for Top Tier Diesel status. The rep told me that some Cosco location have all of the requirements in place and a few stations belonging to the Federated Coop in Canada qualify. The additive package was developed in conjunction with GM, Detroit Diesel, Navistar, VW and Ford. AC Delco does sell an additive package that you can put in your fuel and I'm looking into that. On of the other big things that has prevented acceptance of this standard is that the pumps must have a level of filtration and also water detectors to make sure you are not contaminating you truck during the fill up. The OEMs do have fuel that meets the qualifications during testing but in the real world we are kind of on our own :(. As for your initial question, I don't use an additive package at this time but the Meijer Diesel is considered Premium Fuel and does have extra additives in it, not Top Tier Qualified at this time but it could be partially due to the pump related items?? Good quality fuel is a must with any Diesel engine so if you have a vendor near you that you trust stick with them to eliminate one variable in your ownership experience. While traveling I would highly recommend that you use a truck stop for fueling, the high flow filler does work but you need to keep the flow rate down to about 0.75gal/sec so it does not back up in the filler neck. (Another video topic to come) If they have normal fillers up front those are typically good to, Flying J, Loves, Pilot and TA are all ones that I use during cross country jaunts. Congratulations on the new truck and keep me posted. I'm working on videos today :)
So a Regen is the function that is performed to clean out the particulate filter. This filter is in the exaust stream to keep the black smoke from getting out into the atmosphere. When that filter gets full the temperature is increased to 1,150 F and the soot is burned into ash. If you have ever seen a self cleaning oven, this is the same type of function. I hope that helps.
Chad what version of Torque Pro are you using. I have 1.10.114 loaded and I’m seeing 280-290 oil temps on my 2020 Silverado 1500 3.0 Duramax. I have an iDash that is showing similar values. Banks is aware of the high readings and is working an update to their firmware. Your Torque Pro looks to be reading closer to what I would expect to see, that’s why I’m wondering what version you have.
Kevin,. I'm using the same 1.10.114 version that you have. I will check to see if there is a difference between the standard oil temperature and the custom [GM] version. I think I use the standard version.
Chad Ivan, I set my TorquePro app up based off your video. Banks really thinks the iDash is reporting the temp wrong. It concerns me that yours looks to be reporting the temp accurately and mine is showing 280-290. Banks says the iDash is reporting about 100 degrees high and their tech is working to correct the value and release a firmware update to address the issue. Their test truck is reporting similar to mine (280-290).
Chad Ivan I did a side by side comparison between the GM value and generic and from a cold start (48 Hours since the truck was started) the generic value matched ECT and Trans Temp, the GM EOT value read about 100 degrees high (177) at startup. GM value is definitely wrong. Thanks for the help.
So what I have noticed is that if the Regen has cleaned down to 30% it will end and not restart. If you stop with >30% the next time the truck gets to operating temperature, ~160 F it will restart. The total process takes about 10-15min so typically I don't stop in the middle. If your not actively looking you would not even know it is happening. Thanks for commenting and for watching.
Great video! When do you plan on doing the oil change? Will the dealer do it or will you do it yourself? Heard the oil for this engine is hard to come by.
Oil was changed before this video, I'm waiting on the oil analysis to get finished up before I post it. I bought the oil and did it myself and it is currently had to find. The strike should be finishing up soon so stock should be getting delivered again.
This engine calls out Dexos D oil, this is only available from the GM Dealership at this time. It is a 0W20 low ash oil. I'll show it on the video to post tomorrow :)
I am using the Torque Pro app found on the Google play store written be Ian Hawkins. This app along with the OBDLink MX Bluetooth OBD2 adapter has worked really well and has security you don't find on cheaper models. Thanks for the question.
I'm using Torque Pro for Android. It is on the play store and is written by Ian Hawkins. The phone is a Pixel 2 and the Bluetooth adapter is OBDLink MX, purchased from Amazon. Thanks for the question.
They are really close during light footed driving but it definitely does have the ability to burn more fuel if you put your foot into it or if you tow heavy loads fast. The 3.0 has almost 25% more torque than the 2.8 and that translates into being able to burn more fuel. Thanks for the question.
I tried reading through comments to see if anyone already asked this question. But what exactly is a regen and does a light come on when this is occurring?can it take more than one trip? I’m really interested in this truck for the mpg but have only owned gas trucks. Trying to learn more about diesels! Thanks!
Tyke, no problem. I'm hoping to get a diesel 101 series published to help answer these questions for everyone since the motor is now just about $1,000 over the 5.3 gas. So a Regen is when the diesel participate filter in the exhaust gets cleaned using a little bit of extra fuel to heat the ceramic filter up to around 1,200 F. The process is very similar to a self cleaning oven. There are some tell tale signs that it is happening, higher idle when you are stopped, fans possibly running and a little big of a different engine tone. It take around 10mim and happens at a minimum of every 640miles if you are towing, city driving it will be much lower, possibly every 120 miles. There are no lights that come on during normal operation and you can interrupt the cycle. With that said if the system can not keep its self cleaned you will get a message that will tell you you need to keep driving till a cycle gets finished, a short drive on the highway/rural road should keep it operating properly. Other things to think about include proper maintenance, DexosD oil, fuel filter replacements, and adding DEF to the truck. These will be detailed in a future video. Thanks for the question and for watching.
with the newer DEF and DPF emissions parts on these trucks, (2020 silverado 6.6l diesel) , i don’t know much about diesel, How would these trucks do as a daily driver/short trip truck, (no deletes) no towing or hauling, 6 miles to work and 6 miles back home during the work week? and 30 to 40 miles on the highway every other weekend. i just want a big truck with a diesel engine. P.S i don’t care about the mpg or the cost of diesel.
Man I really like them mileage numbers. I have a 2005 Duramax that I love but I’m really looking at them 3.0 duramax trucks. I like them a lot. Great video. I would like to see the same drive towing your camper mileage maybe.
It is on the short list of videos that I'll be doing, weather depending maybe later this coming week. I will be doing the loop twice, once at 70mph and once at 65mph just to confirm the wind resistance/mpg change you get. Power isn't a problem, even 75mph is no problem but your trailer needs to have different tires to sustain speeds that fast. Thanks for watch and commenting.
I use an Android Phone with Torque Pro app and a Bluetooth adapter, if you have an iPhone you need to get a WiFi version. There are several apps available for your platform. I have a video on how to set up the one that I'm using :)
On the 3L Duramax- I see the axle ratio is 3.23 and in the Z71 it is 3.75. I am new to the diesel world Looking at this truck to pull my loaded 5,500 Lbs. camper. I know in a Gas truck this 3.23 would be terrible. Can anyone elaborate with the diesel and the 3.23?
We have had a very mild winter so far this year but from what I have been told using the block heater the truck should have no problem down to -40 F/C. We have had some 8 F nights and it started without any extra assistance from the block heater. I will be posting the coldest start that I can capture in March. Thanks for the question and for watching.
Temperature at 225 until the 4:30 marl? I’ve seen at least two 3.0 engines blow because of this issue by GM. It seems your temperature gauge keeps bouncing and it shouldn’t be, I hope GM fixes this issue.
This engine has a pretty complex cooling/warming solution, something similar to what was used on the Volt. It has a separate cooling circuit for the head, block, engine oil, transmission oil, heater core and then radiator. In the interest of fuel economy it will only circulate coolant through the head since it is the first thing to warm up, take that heat and warm the cabin if necessary then add some heat to the engine oil. Once the block warms up it will change to pull some heat from that also. The next thing to get heat added to it is the transmission oil. Only once all fluids are up to temperature does the ECU allow some coolant to flow through the radiator. In my book it's really neat technology but could be prone to failure. In the past GM has done a good job of shutting down fuel to an engine that is overheating and I expect this one is similar. The blown engines, I believe are going to be related to the air/water intercooler failing but only time will really tell. I'll keep everyone posted if something does go wrong. Thanks for the comment and Happy Easter.
Chad Ivan I am extremely interested in this engine but not until GM gives an option for max towing AND corrects the over heating issue. After I commented on your video I did a quick google search of 3.0 Duramax overheating and I was shocked! With the way your temp gauge was bouncing around I would be terriftwling 6,000 pounds. Glad you haven’t had any issues, however complicated it is believe me it shouldn’t be and that temperature should not be bouncing around or going over 210 and to be fair the big Duramax doesn’t bounce or go over 210.
I would love for GM to come out with a heavy half ton truck that would have higher payload rating, maybe 8600 gvw, floating rear end and a engine driven cooling fan on the 3.0 Duramax. That should give a tow rating of 13k or so. If that came out I would go with a truck like that too. Not holding my breath, just hoping they do something.
Torque Pro and the Track Recorder add in. I have a video one my channel showing how to add some PIDs that are not part of the standard package. Thanks for the question and for watching
