I review a 2024 Chevy 2500 6.6L Duramax Diesel L5P Engine and see what kind of real world Fuel economy (mpg) these new duramax engines are getting. I explain why Emission , DEF and increased DPF Regens may be causing worse fuel economy in these new engines then in older duramax diesel engines.
What I Use:
Engine Oil - amzn.to/4aEbtNE
Engine Oil Filter - amzn.to/3J1nDUM
Engine Air Filter - amzn.to/3JMmMVV
Cabin Air Filter - amzn.to/3JMZAHh
Gear Oil - amzn.to/3PoIcxa
Penetrating fluid - amzn.to/3EOclkx
Rust protection - amzn.to/3Zo0Rh6
Towing Gear:
10 ton Pintle hitch (2.5" receiver) - amzn.to/3r7Axvm
7 Ton Adjustable hitch (2" receiver) - amzn.to/46i2iAf
Adjustable Pintle hitch mount (2.5" receiver) - amzn.to/3RqHGS3
15 Ton Pintle hitch - amzn.to/45SaCqv
10,000lbs Tie Down Straps - amzn.to/3ZBnxeh

To cap off this mini series with this brand new 2024 Duramax second gen L5P diesel engine, I figured we would put this HD chevy 2500 on my fuel economy loop because I had heard rumblings of this new truck and second gen L5P duramax diesel getting rather poor fuel economy in comparison to the first gen older L5P duramax diesel engines.
My fuel economy loup consists of city MPG and Highway MPG to get a good real world fuel economy combined MPG.
diesel engine naturally are more fuel efficient then gasoline engines for 2 major reason, the first reason is because diesel fuel has more energy in it then gas.
the second reason and more important reason is that diesel engines are have better thermal efficiency then gas engines. meaning diesel engines are better at transferring chemical energy into mechanical energy. they do this by utilizing higher compression ratios thus making diesel engines simply more efficient.
so dispite this HD chevy 2500 weighing over 8,300lbs it can still be an efficient truck.
the one issues with the modern diesel engine however is the emission systems that certainly have an impact on fuel economy. the number one reason is because of DPF regens. this happene when the diesel particulate filter get full of soot and need to burn it off the engine will use a greater amount of fuel to elevate exhaust temps and well this hurts fuel economy big time.
overall we finished with about 18.5 MPG which in my books is not bad!
Hope you guys liked the video!

It’s almost like those people that insist on having a diesel to idle around town and occasionally run down the highway and maybe pull an aluminum fishing boat are surprised when the truck does a regen all the time and sucks the fuel down

Have a 21 Duramax with 55K miles on it, recently had 2 long unloaded road trips, 400 miles and 1,200 miles round trip. Both trips I averaged 20.5 mpgs with one regen in each trip. Towing my 9,500lbs 5th Wheel, I’m averaging 10.6 mpgs. Trucks big so the weather plays a huge role. If its windy, fuel economy is horrible that day but overall I’m shocked with how good the fuel economy is. Have the banks idash, truck regens every 800 miles regardless of where my DPF% is. Love your reviews, you are where I found out that I need to clean my MAP sensor. Do it after every oil change now.

I have the 2024 2500 High Country with the Duramax. Only have 550 miles on it, about 65 miles of it towing my 12K 5th wheel. I bought it specifically to tow my camper and not as a daily driver around town. I did not look at fuel mileage only because it is so new but, glad to see the normal fuel economy is pretty darn good. I have a Volvo XC90 and get 21 MPG at best running around town and what not. Pretty amazing for a truck of that size and weight. Great video. Thank You.

My 2023 L5P GMC Denali dually will get close to 18 mpg highway, but I am pretty disappointed with my towing mileage. When towing my 15k 5th wheel I am down to 7.5 mpg average over 600 miles. Granted I had some pretty strong winds on the last trip, this seems a bit off to me. My last truck was a 2017 L5P 3500 SRW and I averaged 9.6 mpg towing the same trailer. Both trucks had Banks Derringer tuners and Banks Cold Air intakes. Regarding the intakes, with the factory intake and 8000 miles on the odometer I was only getting 200-250 miles between regens towing heavy. Then I added the Banks Cold Air Intake and now I consistantly get 650-700 miles between regens while towing. What is really interesting is that when watching the soot load with my Banks I dash I can watch the soot load decrease while towing and now the truck usually goes into regen because it has timed out and not because it is full of soot. Very interesting. I have sold a few of my friends the same set up and their results are the same, much increased distance between regens! When running empty and hand calculating my mileage, I am usually getting 1-1.5 mpg better than what the computer shows, but after my last trip loaded the computer was pretty close. I will also add that I increased tire size from the factory 235/80R17 to a 255/80R17 that is about 1.5 inches taller. Now my speedometer is dead on accurate, but with the factory tires I was showing more miles traveled than I actually was going as verified by my gps.

@robertothmer7137 Месяц назад

The technical information you include in your is quite interesting and allows us to better understand the emission requirements and how they limit a diesel engines MPG. I will come up with a similar 85 mile route here in upstate NY and report MPG with my 2024 2500HD gasser. 87 octane fuel here is about 80 cents/gal less, we run no DEF and don't pay the $9000+ premium for the upgrade. Should be an interesting comparison.

You want to know for sure what a modern diesel engine is capable of when it comes to MPG at a given performance level? Delete it, don't put any crazy tunes on it, but run it without all that junk bolted on (for science!) and see. Apples to apples comparison right there... People have been doing it for years, the concept isn't rocket science; you have an engine that basically runs like an air compressor, if you want it to run efficiently, then let it breath and don't force it to pull exhaust back in as well. You wouldn't have people wasting DEF fluid, you wouldn't have an SCR system THAT INJECTS DIESEL into the DPF during active regens, and you wouldn't be wasting all the extra diesel fuel in the decreased fuel efficiency from the air restrictions created, fuel burned during active regens, and weight added with all the added emissions equipment and extra DEF fluid that you have to haul around. Modern diesel emissions standards, and ICE emissions standards in general are pie in the sky lunacy brought about by your friendly Karens at the EPA who can't help themselves when it comes to telling everyone what to do.

Had a 24 Silverado Duramax as a company vehicle for about 6 months before ending up in a 23 Superduty 6.7 (SO). The Duramax was getting about 15-16 mpg mixed driving. Also regened 250-350 miles. Superduty getting about 2mpg better and regen only happens every 500 miles with computer showing 60% DPF load. Same driving habits. Otherwise I loved that Duramax.

@TheGettyAdventures 2 месяца назад

Fair enough! I think both the duramax and power stroke platform are solid choices. But for whatever reason is does seems like the druamax engines are less efficient with more frequent regens exactly as you experienced

Some specs are missing, rear axle ratios, transmissions, is Ford a 10 SPD, 2 or 4WD, one ton(dually) bed length, tonneau cover, tires and pressures. Oddly enough ambient air temperature, The colder the worse the mileage like 2-3 mpg less. I've got a Dodge Laramie 3500 quad cab, 4WD, SRW, 8' bed not covered 5.9 Cummins no mods, 48 RE trans, 3.91 axle ratios 5.9 Cummins, currently my AC condenser is off vehicle so whatever difference that makes to the air to air/charge air cooler is unknown. city 16 mpg, hwy/frwy 22 mpg plus, approximately 60 mph seems to be a threshold, 70 mph is 20 mpg, 80 mph is 16 mpg, 90-95 mph is 11+/- mpg. Normally I drive for mileage and I assure you accelerating up to speed makes a big difference but you don't want to anger other drivers with lake freighter takeoffs, besides after driving like this the black smoke pours out during hard acceleration. Goodyear all terrain tires 265/70x17 (121) 60 psi front, 70 psi rear. Although I haven't done this to my pickup I had a 1989 Chevy hi top Kellogg conversion van just a good wax job was worth 2 mpg from 12.1 to 14.1 mpg driving roughly the same, say this because when you put in the effort you tend to influence your made a difference hypothesis somewhat

Yep spot on. 17-18 mpg average. On a long trip it’s 20 on the computer, but I haven’t verified that manually at the pump. And yes lots of random regens that will take it down to 14 mpg. I guess this depends on usage, but for me I’m guessing every 200-250 miles it does a regen. Road conditions, load, and how you drive doesn’t seem to matter…it’s all about the engine. I can’t figure why it’s only 10-12 mpg towing only 3-4k empty or full trailer…I’d think empty trailer would give better mpg, but it’s as if the truck knows it’s towing so just drinks double the fuel.

@Jon651 24 дня назад

My Silverado 2500HD Duramax LP5 (2nd Gen) got relatively bad mileage for about the first 1000 miles - 16mpg on the highway and12-13mpg overall. That was a real shocker coming from my 2013 2500HD LMN that had the 6-speed Alison and was a 4x4. It got 16-17mpg overall and 21-22mpg on the highway. I live in Central Florida with no hills or snow. Now that I've got nearly 2000 miles on my new truck, the mileage has shown a marked increase - 20+mgp on the highway and 16+ overall which is approaching that of my former truck. I think this may be due mostly to the engine management systems learning my driving style and the motor breaking in as well. I can tell the computer is learning as time passes - for example, when new and under acceleration from a stop with a constant pedal position my truck would really surge after about 2 seconds from taking off, without me pressing the pedal any further down. Now that behavior is not nearly as noticeable and acceleration is comfortably constant when taking off from a stop. In my former truck I could always tell when it did a regen, because the instantaneous mileage dropped to11-12mpg regardless of where I was driving.

@rogercyr1551 2 месяца назад

No tow, I've seen 21.4 mpg (U.S.)/25.7 mpg (IMP) with my '23 2500HD Denali. I use it almost exclusively for road trips, mainly highway, so when regens happen they mostly take place when all combustion components are hot, to begin with. I haven't noticed any fuel economy harm caused by regen.

6:31 you should also include that fuel economy is not the same as emissions. a common fallacy the anti-emissions people (I'm not saying they're good, I'm just saying they work) use is that "but mah old truck gets 20mpg!" line, when in reality a 20mpg pre-emissions truck is SIGNIFICANTLY dirtier, upwards of 97%, than a 15mpg emissions-compliant truck. I've always wanted to do testing on various diesel trucks to see the difference, and would love to organise something like this but it's so impossible to get a large enough sample size to make a meaningful argument.

Considering your conditions were optimal, I'd say that's not so great. There's no traffic anywhere, there aren't a ton of red lights, you're able to keep a steady speed, you don't have to blast the air conditioning and you drove like grandma. That's really the best that anyone could hope for. That said, it's better than any truck I've ever owned.

@sargenthp 2 месяца назад

Ummm.. Pretty sure "Passive Regen" is when the exhaust system is hot enough to burn off soot without assistance (such as towing heavy loads). "Active Regen" is when the system starts dumping fuel into the exhaust to heat up the exhaust and burn off the soot.

@EagleTalons1 2 месяца назад

Lets also keep in mind that a crew cab with usually no more than a driver and maybe 1 passenger and rarely any passengers in the back isn't doing these trucks any favors on weight efficiency. I've been struggling to find a regular cab Duramax looking online because the manufacturer and dealers want to sell that extra big extra pricey truck that has no practicality for what I need. So far I found 1 that according to the dealer listing $55,000 So of course you don't pay sticker so I offered $50,000 cash and they denied my offer so on top of the fact that the truck I want is hard to find but hard to buy for a reasonable price. 🤷‍♂

I bought my 2024 L5P to tow and haul everything all the time. 30,000km on my truck not once have I looked at the fuel economy. It’s a truck, the fuel economy is gonna be different based on weight being hauled. If anyone is concerned about fuel economy when buying a Diesel truck you may as well just not buy one lmao

@countcuda70 2 месяца назад

They all have issues. Torque the crank bolt to the proper torque And you won't have an issue. Cummins eats the grid heater bolt. Powerstroke still uses the CP4. You can pin the crank on the Duramax. Change the intake horn/grid heater. Powerstroke can be swapped to a DCR pump. Easy fixes for all of them

The L5P is well known for one of the fuel mileages of all time. Oddly enough, a chief engineer stated in there discussion board for the L5P, that fuel mileage was one of their points of interest. With this in mind, it is easily one of the fuel mileage trucks out there.

would you be crazy to buy a brand new 80K duramax, delete it and say fuck it to the warranty?? i live in utah and everyone at my job drives a diesel(not part of the job, just a lot out doorsy folk), majority of them have it deleted. Utah don't check emissions if your address is in a rural area and a lot of the cops don't seem to care either.

Modern diesels suck because of emissions requirements. How dumb do we have to be to have a fuel injector in the exhaust stream. Also my ford lightning is just a toy so I can do real truck work with it and still need my diesels for long heavy loads. So electric a total joke. Diesel a scam due to emissions.
