Regens, DEF and Emissions Explained on the 6.7L Cummins - 2013 through 2017 Ram 2500 

As a class 8 diesel tech, I have always wondered why Cummins uses a dedicated doser (injector) for the doc/dpf on their heavy duty engines and not the light duty ones. Just like you mentioned, it greatly reduces engine oil life by way of fuel dilution. We have had trucks in our medium duty shop that have injectors fail and due to the extra fuel during the regen cycle, the crankcase was over filled by up to 30% and took out the main bearings on the crank. So entire engines have been replaced because of the way they introduce fuel for regen on the small engines. Crazy! This was a good video man. 99% of the RU-vid vids on this topic are way off on their facts and-or terms.

A few comments Christian. Excellent video on the emissions system. While urea is a component of urine, DEF is NOT made from urine. The urea used in DEF is very carefully synthesized from natural gas. I believe you said DEF was 38% urea. It is actually 32.5% urea and 67.5% deionized water. It is very carefully made and very pure. I really liked your honesty about how well the complicated and expensive system works to keep our air clean. That is not said much in videos about diesel exhaust, efficiency, power, or longevity. Yours was a refreshing and important discussion. You pointed out the pluses and minuses very fairly. I have a 2017 Laramie crew short bed. I can honestly say that I have never experienced active regeneration in this truck min over 22000 miles. However, we put 99% of our miles on it towing either a gooseneck horse trailer at 10-12K pounds loaded, a flatbed hay hauler (usually with 5 tons on it), or our Outdoors Timber RIdge RV (shameless plug for an Oregon product) trailer which is about 7000+ pounds wet. I think our exhaust temps while towing make active regeneration unnecessary. I have driven this truck empty from Spokane to Fargo North Dakota (about 2400 miles RT) on less than 2.5 gallons of DEF when running empty and not pulling a trailer. When pulling the Outdoors RV TT it takes more than twice that amount. I was very surprised when I first discovered that DEF consumption rises dramatically when hauling heavy loads. DEF cost is still almost insignificant in the total cost of ownership. That said, this is the best truck I have ever owned bar none. It is my 5th Ram since my first in 1994. It is so comfortable and easy to drive even with a very heavy load. I cannot say enough good things about it. A truck just can't get much better. I just added Firestone air bags on the rear and Bilstein Shocks all around along with Bilstein dual steering stabilizers. I had Timbrens on the rear and was happy with them towing, but the ride empty was harsh. Not any more. Excellent upgrades to the ride and level towing ability for sure. Keep up the good videos. I stopped watching a while back and now I am catching up with the ones I missed. Good job on all of them. This was particularly good and necessary to balance some of the bad stuff out there.

rewatched this and now I'm exhausted.

As a former diesel owner without DPF, this is a great explanation on regen. Thanks

This video has solidified my opinion to purchase the 5.9L Cummins 3rdGEN Dodge ram 2500 (05 to be exact I like that year of diesel rams) so that I don’t have to worry about deleting it as it comes stock that way and I don’t have to worry about all this DEF shih and the money that I saved on buying a luxurious truck like yours I can just spend a couple grand to redo the interior completely and make it an even more badass truck than what I could get off the lot.

Thank you for taking the time to put this together! It is certainly helping me as I move towards buying my first diesel truck. Debating between 2500 and 3500 dually.

Fantastic info. Loved hearing both sides. I'm a female and have had my 2017 Ram 2500 since Dec. of 2016. I am fully committed to running it until it completely falls apart. I hope to have it at least another 20 years. Love my truck. I am a horse and agriculture gal too so I want to be good to the earth, but honestly I want to keep my truck running top notch even more. I'll offset my carbon footprint some other way. 😁 Also been having codes regarding the emissions system and after replacing the actuator, removing & cleaning the EGR valve and still getting new codes I am really considering deleting it. Next is to clean the turbo before making that decision. Since I only run my truck around town anymore for the last few years it makes sense that it is getting clogged up. At least now I understand why. 😊

We have a 2016 3500 with 22,000 miles now. I had the REGEN process happen once in the first 500 miles and it hasn't done it since. We tow a lot. I did have the service def system light come on once when we were driving through a national park all day at low speeds up and down hills with the exhaust break on. It turned off the next day so i didnt take it in. I go back and forth on whether to delete it or not as this will be my "forever" truck with ALOT of miles. NICE VIDEOS.

Hey man good vid. I’m one of those guys that ordered a brand new 2022 Cummins just because I wanted one. I have a 4700lbs boat I can tow around if I have to. The truck is going to be my daily driver I drive about 30km a day for work on the highway at 100km/h. Hope I didn’t make a 90k$ mistake

Great Job explaining this system. 👍🏼

LOL! "I'm a tree huger, but I like guns and diesel trucks" haha made my day!

Very good video. I did some of my own research before encouraging dad to replace the gasser F350 farm truck (which was a dog and which whenever I would tow with it, I had to have it screaming to make any hay) with a 2018 Ram 3500 chassis cab with Cummins engine, and I have become convinced that the modern diesel engines and the transmissions backing them are probably the most reliable of any era, and that the exhaust emissions would be the weak spot as far as reliability. However, we use this truck in a way that will generally minimize the amount of active regen that would be required. The truck has a 2,500 lb bale bed on it, with a 1,200 lb cube feeder on top of that, so when it is being driven, it is working. The truck will be driven slowly in the field, but there is a 45 mile highway trip from home to the field. So far, the only complaints that we have had is the DEF consumption, but I am pretty sure that the DEF tank was NOT full when we left the dealership, as we put some in during a trip last week. 1,500 miles on it so far, and so far, so good. I am like you... a bit of a tree-hugger, but I love diesel trucks and guns. IMO, the addition of all of this emission equipment should make people really consider whether they really need a diesel pickup whenever they are buying one, whether their normal usages of the truck is going to be something that will necessitate a diesel truck. If you just like the sound of a diesel truck, and you will not be doing much towing, but instead off-roading, you might be better off with a gasoline engine. If you are going to be towing in town with lots of stops, you are probably going to be better off with a gasoline engine. The gas engines in todays trucks are not bad engines in city driving, especially with the modern 6 speed transmissions and the low rear-end gear selections that are now available. My experience with pulling with a gasoline truck has been that take-offs have a surprising amount of alacrity in city environments, and it is only upon reaching highway speeds that it becomes significantly harder to keep speed than a diesel. If you are going to typically have a load on, traveling at highway speeds for a significant portion, you should probably have a diesel truck.

I have been looking at both gas and diesel new trucks. I believe that all of the emission controls on these diesels are an evolution in progress much like gasoline engines went through in the 80's and 90's. I have decided that currently there are too many over complicated "bandaids" on these new diesels. The odds of problems, cost of repair, and service of these diesel trucks is more than I want to risk at this time. I will probably buy a gasoline V8 for my next truck as it will meet my needs but it is not what I really want. The risk of problems, extra costs, time in the shop are too much of a gamble with my hard earned money.

Great video, thanks for the tutorial on the emissions stuff!

Good informative video. I drive a 2017 Ram 3500 with the 800 ft/lb version Cummins and 68RFE transmission. I recently got a Bluetooth code reader and OBDFusion iPhone app. This lets me monitor all 5 (yes 5!) EGT sensors. I just towed my 15,000 lb 5th wheel trailer to 10,500 ft in Colorado, as well as a lot of other serious climbing in the last week since I got the app. At 60 - 65 mph I am seeing temps of 750F to 850F on average, even when pulling serious hills. On very long hard 6 degree grades, I still never saw higher than 940F, and that was just for a moment or two. So in my experience, it is pretty hard to get up to passive regen temperatures of 950F, even while towing heavy in the mountains. These temps are from the first of the 5 EGT factory probes, and I don't know how close to the cylinder it is. The app also lets me see the EGT downstream at various points, so I can monitor it while it is in regen. I have only seen it in regen once since getting the app, and the temps at the DPF were around 1050F at the highest. And if the OBDFusion app had not told me it was in regen, I never would have known. It was imperceptible.

Great explanation. I have trouble explaining this stuff when my buddies ask. I will now direct them to this video haha

"Diesel Exhaust Fluid Fluid" :P Really thorough explanation. You covered pretty much everything I think. Like you said the whole thing is a balancing act: Too hot and you get NOx (NO1 and NO2). Too cold and you get DPM (Soot). All of these systems do a great job of balancing that out to reduce both kinds of emissions, it's just a shame you have to strangle the engine, dirty-up the intake and oil, dump your unburned fuel, and repeatedly purchase cow pee to do that. Also the cost of replacing a faulty DPF is more than the cost of a full delete, which I think is I think a pretty common trigger for people to go down that road. If you are ever concerned about getting caught with a deleted truck on a trip somewhere, there are stealth kits available. It's basically a straight pipe but shaped like it still has the DOC/DPF/SCR intact. Some come with block-off plates for the EGR, but still have to leave that giant-ass cooler in your engine bay even though it can't be used. Some just rely on the tuner to keep the EGR valve closed, but then you take the risk of it getting knocked open somehow while the system isn't functioning. Either way, it'll pass a visual inspection if a cop decides to stop you and look under the truck. **Edit:** Apparently I've gone crazy. Doesn't look like there are stealth exhaust kits for sale - people either hollow out their own or get a spare exhaust from a junkyard and hollow that out instead.

Oxides. NEVER Dioxides! What bothers me the most is the fact that class 8 trucks are not as regulated as the personal diesel owner. It's the lobbyist group that get the pass, but not the citizens.Again, all politically driven rules.

Nice video. I've had 2 Cummins trucks..a 1997 2500 and my current 2006 3500. I'm so glad I don't have to deal with emissions on,my truck, but im getting the fever for a new truck. I've gone so far as to test drive a couple. Man they are nice. Anyway nice video. Glad you aren't a total tree hugger and you like guns and diesels. Tennessee here. Take care

Thank you for this video. Much appreciated it

Not bashing on your video or you, just correcting. Nitrogen oxides, more commonly known as NOX is, as you stated, a byproduct of heat during the combustion process. Egr, is the process of taking exhaust gas from the manifold, pre turbo, and routing it back into the inlet manifold. Exhaust gas is inert. That is why they use it. The inert exhaust gas is cooled via the egr cooler then introduced back into the combustion chamber to cool the combustion chamber. Which reduces NOX.

I think you did a great job on this video!

I’m not one who considers myself an environmentalist or one who believes in man made climate change. But I can definitely appreciate the benefits of emissions equipment. It’s really not a big deal when out in the country, as the exhaust disperses quickly and the crap will naturally settle out of the air and or break down. In large towns or cities, where you have a lot more vehicles crammed onto the road, you could easily choke people with all that crap in the air! I live in Denver, and just bought a 2013 Ram Cummins, I’m gonna leave the thing stock, and every time I refill the DEF tank remember I don’t have to wash soot off the side of my truck!

Just a question, do you not have a DEF gauge? I always add one jug of DEF when it hits 1/2 on the gauge

One BIG thing I didn’t hear you say everyone should try too do . When it is in Active or Passive Regen LET IT FINISH do not turn off the truck , you can tell it’s in one by the sound or if you have a monitor watching exhaust gases rise over 900deg . Turning it off causes issues

Good video and about as objective a one as you're going to get on this topic. I like how you point out the possible reliability issues with emissions intact but still acknowledge that they do greatly curb emissions relative to previous generations of diesel engines. The legality of deleting is pretty straight forward...it's not allowed by the EPA, but different states have different approaches when it comes to enforcing and supervising that. I don't like the complexity of modern diesels, but I also acknowledge that progress needs to be made on dealing with their emissions. Kind of like the EPA's regulations on gasoline engines and fuel quality back in the 70's and 80's, I imagine there will be growing pains with diesel emissions technologies. But I hope that over time they will become more reliable and less expensive to maintain or fix. Here in the US, diesel owners and enthusiasts cringe at the EPA's stance on diesel emissions, but go look overseas (e.g. Europe) where for the longest time they had few, if any, regulations on diesel emissions and the air quality in their cities has suffered horrendously (they also have a lot more diesel passenger cars than what we have here in the US). I'm torn on longterm ownership of a modern diesel. I'd like to minimize my environmental footprint, but I also don't want to have to pay for a new exhaust system (and potentially a major engine overhaul) 100k-150k miles into ownership. What I would really like to see from Cummins and other diesel owners is longterm feedback on how the emissions, and engine reliability, fares over the longterm (150k miles and beyond). It sounds like the newer diesel engines (2013+ for Cummins) are much better at managing the EGR and DPF active regen's and also get better mpg's than what the earlier versions were getting. All that said, the 2013+ Cummins are still young, relatively speaking, and I'd like to see how they're doing 5-6 years from now with several hundred miles on the odometer. BTW, PNWreckage this isn't all directed at you. Mostly this is just me airing out my thoughts on the topic. Though if you do end up keeping your Ram for the longterm, I hope you continue to make videos and keep us posted on its reliability.

Very informative! Thank you for the vid!

Glad I found this vid. I was planning on doing a delete on my ‘16 Cummins but I’m gonna hold off as I’m planning on getting a newer one. I hope I can find a sap to buy this def hog though.

Way better Intro. short and to the point! I wasn't a fan of the old one.

Nice work I drove tractor trailer for 10 years

Great Video. I have a 2015 6.7 Cummins with 15,000 miles on it. So far I've had 2 active re gens during that time. I try to do as few short trips in my truck as possible. I absolute love my truck and for the money it beats (IMO) Ford and Chevy. After watching a few of these videos, I'm started to get concerned that maybe I should have brought one with a gasoline engine instead. My whole reasoning for buying a diesel was because they last a long time. I hope I didn't make a mistake. I plan on keeping this truck for 20 years.

Nitrous Oxide is N2O that is not produced in the exhaust. The NOX sensor measures the level of Nitrogen Oxide NOx

GREAT VIDEO and Presentation ..I suscribed👍👍👍👍

Good video and thanks for the info....I feel lucky as crap...my DEF consumption on my 2018 2500 is about 3 gallons every 7500 miles.... don't plan on doing any deletes for a while, my dealership offers a 20 year 200,000 mile warranty; so I will wait until I hit one of the marks then play

Great info, thanks for the details

The EPA has accomplished nothing by forcing manufacturers to design and install these systems. If they really cared about the environment the first consideration should have been to reduce diesel consumption. The diesel engine (pre-DPF system bullshit) was already much more full efficient than the gasoline. If a truck uses much less fuel without these systems then it is a huge win for both the environment and the individual who owns the vehicle. The DPF system has added thousands to the cost of the vehicle, increased maintenance costs and increased potential catastrophic failures , decreased engine performance AND decreased fuel economy. One does not have to be a scientist or engineer to understand this. Do the simple math. Bottom line: the very high cost of these systems has completely destroyed any marginal reduction in greenhouse gases. The EPA wrecks everything it touches! I'm ripping my DPF system out as soon as the warranty is expired.

"the giant crap shoot that is the emissions system is"...lol...that is the best summation I've heard yet

Liqui Moly makes a DPF cleaning gun and wand that can clean out your DPF pretty well. They have videos of cleaning car DPF's in Europe. Part #'s are 7945 & 7946. The cleaning fluid part #'s are 20110 & 20112. I think you can order them through AutoZone. They buy it from a vendor called IMC.

HAHA... Thanks for that @5:17 good chuckle

Thanks this helped a lot

Great job!!!

Hey PNWreckage, great videos man. Very informative. I am buying a 2018 in the coming months and will be using a lot of the pointers you have said. I have a question, you may have answered this in one of your previous vids but what do you do for work?

I had a Cummins and here is the deal: they don’t tell you that this engine will start clogging up the day you drive it with soot. After 15K miles my engine performance went way down sluggish and non responsive. My engine also got a lot louder on the top end valve train. So with the black smoke now going back into the crank case oil - when you do a oil change and after 100 miles that new oil is black like tar looks horrible. You have to use synthetic oil with new def changes so you will need to buy an oil change plan or pay $180 per change. Then you have fuel filters to change ever 15K miles. If your DEF emissions plugs up it may be covered under warranty but you truck will be shop for a while. Also don’t forget about the67,000 service that is $1500.. if you are out of warranty between your under the hood emissions and under the truck exhaust dpf regeneration you can easily pay 1000 of dollars on repairs and part. A turbo replacement is like $7000.00. Injectors replacement are $8000-$13000. I sold me Ram Diesel at 15K miles and went back to a 1500 and love it.

I just bought a 2016 Cummins, from trading in my 2011 deleted Duramax. These are easier to delete and something I'll definitely do

This video makes me wonder what is more efficient, burning more fuel with all the emissions equipment, or burning less fuel without it? 🤔

YES!! Next is HID light😁 Now I've heard "chipping" it can unlock a lot more of its potential. What are your thoughts on that?

The DPF is used to remove particulates down to 2.5 microns. A micron is a very small particle.

Say you modified your exhaust to improve the efficiency, what do you do about the extra injection of diesel into the exhaust stream? You also mention software upgrades, are these automatic or are they done at the dealer?

dpf hates stop and go, start and restart for short period of time. they said diesel now is clean but im not buying it specially doing the regen

I live in a city environment, LA County, and I don't tow anything (yet). So I would accumulate all the soot very quickly? Also do I need to purchase the engine warmer or does it come with it?

Great video! Off topic, why did you buy the 2500 over the 3500. Just the suspension or?

delete for the win! =)

Thank you for a very informative video. Got my questions answered about the regen procedure. Also- can't help but laugh as I see you wearing a 'Portland' shirt and saying "make us hate this place a lot more in 50 years". _ Didn't take that long, did it? 😀

PNWreckage what brand do you use for your DEF all the time? Been thinking about Mopar not sure what to do for brand. Don't want to give the dealer any excuse for warranty issues.

My state requires inspections in order to register and renew license tags, so anyone who deletes their truck will be unable to renew their registration or sell their truck.

Have you had any issues with the emissions system in your ownership? This is one of my main worries in purchasing a newer truck just like yours. Other than driving habits can a guy do anything to prevent issues

Thank you for the informative videos. We are shopping for 2500 and would love the Cummins however, in Suburban Chicago we have to pass emissions to get tags so I don't believe there would be any way around deleting. Unless you know otherwise?

I got a brand new 2020 dodge2500 sport 4x4 with the Cummings and on my way to a wedding a few weeks after getting it i had smoke coming thru the air vents and the smell of something burning, it hasn't done it since then but wondering if i should be worried?

i deleted my 2016 at 3k never looked back at 17k now running like a champ..... if and when i ever get another its going from the dealership to the shop to be deleted.....

Great video and info. Would like to hear your opinion of the tunes available for the 6. 7 with the emissions left in place. Thanks

Hey PNC, I have commented a few times to your very informative and well presented videos. I now have 19K miles in 7 months on my 2017 RAM 3500 SRW Limited with Aisin. I have been adding a 2.5 gallon container of DEF about every 4K miles. I only got down to the warning light once. I drive with automatic exhaust brake all the time. I am in southern California so I drive 50/50 split highway and city. I cannot detect when a regen is happening? I had one less than favorable tank of fuel only yielding about 15mpg at around 15K on truck, so can I assume my truck went through an unnoticeable passive regen during that tank? I normally average 17-19mpg combined city and highway, and get as much as 22mpg highway while driving to Colorado and back to visit my daughter. I am a diesel newbie so I am not sure if these trucks require the regular California "smog" checks in order to get registration renewed. Does deleting the DEF system affect a smog check if so required? I can only assume it does. I look forward to your reply. Thanks!

I find your videos interesting because I am trying to decide what truck to buy. I am thinking about a 1ton BigHorn DRW for hauling a 5000 lb camper. I will always have a camper on the truck. I have car for to day use. I am wondering about whether it is worth the hassle and cost of getting a diesel for only 5000lb vs a Hemi. I can't justify a diesel but gas 1tons are as rare as unicorns. I am across the river in Vancouver, WA. Gong to Costco today to see what their buying service can do.

"Oxides of Nitrogen" is the correct technical term term for what is produced in Diesel Exhaust, not Nitrous Oxide. Best not to keep calling it Nitrous Oxide, harder to keep the two separate when you keep calling it Nitrous Oxide. There is only one kind of Nitrous Oxide, and only one kind of Oxides of Nitrogen. Just wanted to clarify that for you since you seem quite knowledgeable on the DPF Regeneration subject as a whole.

I only live about 20 minutes from work. That being said, do you think I would be better off getting the 6.4 Hemi? I would eventually be doing some towing, but mostly daily driving.

Incorrect. At higher speeds and higher temps one’s engine is producing the least NOx. The greatest NOx emissions occur below 25 mph. That’s from Cummins own studies. At 25mph one can readily produce more than 5 times more NOx than cruising at hwy speeds. Cummins has white papers on the topic. My Cummins 6.7, as measuring NOx sensors 1 and 2 display about 100-350 ppm on the SCR input. My 2nd sensor at the SCR outlets typically reads ZERO! Yes, zero. It jumps to 1 or 2 ppm at moments when I lug down slow for turns in side streets.

I have a 2015 Cummins and it is not using any DEF. Gauge remains in full after driving 1000 miles. I have never experienced a regen. Any suggests as to what could be cause?

man, I want to delete my 2017 on order but my 15 did fine not deleted. For me when I buy a new truck warranty is a huge thing and if I don't have that I would be back to buying. A old 5.9 and dumping money into that. anyways from Hillsboro,OR good to see some local video's.

i’ve seen in the 2019 ram 2500 diesel owners manual that a parked manual regen can be performed, if so short daily (city) driving shouldn’t be a problem, or would it?

1/ Cummins builds engines for work, not play. RAM needs to educate buyers better on how to operate. Short trips and idling are considered severe duty. imho, "lugging" should be added to this definition. The CTD needs to be run for long periods at 1800 rpm and above, as this ensures proper combustion and least particulates, thereby reducing regens to minimum, and thus preserving the engine oil. If this is not your driving habit, perhaps a gasser is a better option. 2/ Alternate technologies have been developed and proposed to eliminate particulates. I know, as I was a member of a team. But they are not as convenient for drivers as the DPF, so no market appeal to lazy people. Such tech does provide greater air flow, and thus greater power. 3/ Another factor is the quality of fuel, which is rather low in the USA. Instead of placing the onus on consumers, the EPA should be pressuring oil companies to produce a better, more refined fuel. The quality of fuel greatly determines the exhaust components.

I just purchased a 2014 dodge ram 5500 hd *emissions deleted* my husband overlooked that before we purchased it! We are starting our hot shot business and we literally can't run the truck with out one! Needed too know how/or what she we do about replacing or adding one

good shit

Thanks

I'm at 65k miles on my 16' Ram 3500. I send oil samples to the lab about every third oil change and have never had fuel show up on the report. Is this an exception to the rule or is the discussion of oil dilution from the emission system BS? Has anyone claiming oil dilution by the emission system offered data in the form of a lab report? I'm not arguing for or against any of the data discussed, I just like to see the numbers to back up points brought up in the discussion below.

This is why you buy a ‘17 and newer ford, they are the only manufacturer that offers a manual regeneration, it’s called OCR, operator command regen, for us city drivers! We can perform a manual regeneration in our driveway, suck it Ram and Chevy!

I'd love to get a 2500 with the cummins but living here in Cali it's illegal doing the delete which sucks ass.

I plan on weekend highways drives just to be certain I’m getting passive regen. time.

It’s tampons clogging pipes for the qweef

I didn't even know about this like imagine being told you didn't drive your truck hard enough due to that your exhaust never was hot enough to do its job that'll be 3k-5k oof

Again..A quality fuel/oil separator filter can/does remove this "dirty"oil that has the diesel fuel particulates of your filtering systems!

‪i want a 2019 ram 2500 6.7l cummins, i don’t know much about diesel, how would this truck do as a daily driver/short trip truck, 6 miles to work and 6 miles back home? long trip once a year ‬no towing.

Are you going to delete? I plan on doing it once my extended warranty runs out.

It all works against the longevity of a normal engine.

Dumb Q?.. Why an auto rather than a manual? Both are 6-speed. Heard less problems w/manual vs auto trans (Granted. "old" body styles :94-02) I have an '01 1500, 5.2/318 gasser w/a manual,. and would KILL for a "newer" gasser w/ manual. Consistent 14-16 gpm on 60 mile day/6 day-week work run. Are the "new" autos that much improved from the older gens? PJ

how does it have less of an impact if you end up junking junking your engine 100,000 of miles earlier then back in the day?

Bovine urea and water sounds like Bud Light to me

My goodness, you are a font of knowledge. It seems to me that a truck buyer needs to ask Do I need a diesel engine? I mean I see you driving an empty truck ,nothing in tow . I see alot of guys just liking the "cool factor " of a diesel engine and not needing one at all . It's a free country drive what you want but make an informed decision.

I thought that late injection thing was a Powerstroke thing, I know the 6.4L would do that, and it cooked the turbos...

Pretty much, what should I expect being in a city environment?😰

What diesel fuel additive(s) do you recommend?

DEF filled 2 times? wow. I've used 12 gallons in 9000 miles. 4500 were pulling 6000LBS. Seems like 2 gallons will go about 700 miles towing.

You use so much more diesel by using a def system on your diesel (not to mention lost horse power and $1000s to keep it up and huge down times fixing it) that it is ridiculous to suggest that it is better for the environment.

What are diesel emissions. www.dieselnet.com/tech/emi_intro.php

Saving the environment one plastic bottle at a time. 😂

Just sent a e-mail for your specific application.

So the states that test emissions do they simply inspect system or do they measure emissions. We just need the system to be working in Australia. Run an emulator to trick the computer to thinking everything working and remove exhaust drill out honey comb crap out, bang it on the ground put it all back in. Looks stock sounds stock but is hollow. I agree environmental impacts of mass production of these parts and premature failure and sale of your truck and re purchase of new truck balances out a deleted truck that you will own and go on for many many years to come.

Making your engine eat what it shits ffs

To many testing to prove you wrong do you live in California

Delete or just buy an older better and more reliable truck without all the motor destroying epa bs!

If you use Amsoil products in your truck you will save a lot of money and it won’t run a regen as often...

In short buy a 12' pre Def BS...then delete EGR
