MPG, DEF, Oil Usage: 2023 Chevy Silverado 1500 3.0L Duramax Diesel Towing

[@agdamis]

I drove my LZ0 (stock) 2200 miles towing 5,000lbs. Left with full DEF and added only one 2.5g Peak DEF, 1 quart of oil and averaged 16mpg cruising 65mph - 70mph. The truck ran perfect, and trans oil never got over 200F. Truck is awesome.

Check your trailer's bearings. I pulled a 6K trailer in the hills and mountains of Tennessee/Virginia for 500 miles at 65 to 70 mph and got 23 mpg.

[@mattvanbogart]

I have a '23 AT4 with the LZO. Tow my boat here and there. 7000 miles on the truck so far, mostly highway and I've gone through 8 gallons of DEF. I've towed my 6K boat about 700 of those 7000 miles. 17MPG towing with boat in the hills of Central WA state. Power is great. Best driving truck I've owned. Last truck was a 2013 F150 FX4 SCREW with 3.5 Ecoboost. Great power in that truck and about 2-3 MPG less while towing. Rear springs of the AT4 are WAY BETTER than the Ford.

[@GMtkett]

I'm finding a difference between using the Jugs vs def from the Pump. I actually think I'm getting more DEF in the tank then I am with the Jugs. They both say full on the not so accurate gauge. However, I think the pump gives you a better top up because of the auto shut off at the pump as apposed to guessing when it's full with the jugs so you don't spill it down the side of the truck.

[@CatholicBossHogg]

You bought every upgrade except the most obvious one - a larger fuel tank! A 43 gallon titan fuel tank is the first thing I bought when I got this truck. Now my range is 1200 miles without trying.

How much did the bigger tank add to your curb weight and reduce your towing/payload?

Thanks.

[@saltyreef3714]

Great video! As you mentioned, going to the truck fill-up stations will be the best option to purchase DEF. They have high sell volume and its always fresh, plus it's way cheaper - around $2.5/gallon here in California. And of course, towing goes through def like it's thirsty 😂

[@3.0dmax]

First off, excellent vid. Second, not trying to nitpick, but the DEF tank is 5.3 gallons. Also, you're driving along interstates for the most part. Every Love's, Pilot, etc has DEF at the big rig lanes and it is much cheaper there vs the 2.5g jugs. Yep, the LZ0 uses more DEF than the LM2 unfortunately. DEF is used to combat NOx. Higher RPM and EGTs makes more NOx. Slow down 5-10 MPH if you're extremely low or empty on DEF and need to make it somewhere to fill up. On that note, it's not like it's immediately speed limited if the DEF tank runs empty. Plus your Banks gauge should give you actual percent remaining vs the dummy bar gauge on the cluster.

[@Pickuptrucktalk]

Dammit. Why do I keep getting the DEF tank size wrong. I swear.

I did a 3600 km trip on my 2021 LM2 this winter towing the sled trailer loaded and was absolutely blow away by how much Def this thing used. I was 4 jugs total. I think it’s usage is high in general even when not towing. We drove from a 6600 km road trip this summer and I used 2.5 jugs. My 17 cummins burned a jug every 6 months with the same driving habits. I’m putting a jug in every 4 weeks currently. 95 percent highway driving. Regarding the oil consumption- I’m convinced the dealership oil is the problem. When I am running valvoline I don’t get any burn off. The AC Delco stuff alway burns off a quart by the time I’m down to 30%.

So far very happy.

[@bantizzle79]

I know GM says it is normal to burn that amount of oil per 1,000 miles, but it just seems excessive. Puts a lot of liability on the owner to check and add oil frequently. Majority of owners are not diligent in checking oil levels.

[@wheel1775]

That is concerning. Most people aren’t accustomed to checking oil anymore. If the oil is burning off, does that mean fuel is bypassing the rings also? That concerns me that the fuel is contaminating the oil. That being said, I did just buy a Silverado with the LZ0, so I’m holding my breath.

I have a 2021 Silverado RST (LM2 3.0 duramax engine) since 32 months with almost 50k miles on it. The 2 first oil changes were done at the dealer for free. It was a deal they had when I bought it new in Ontario, Canada. I change the engine oil every 6k miles. After the 2 first oil changes I've been doing the oil changes myself with Amsoil engine oil. It burn alot less engine oil since I've switch to Amsoil!! For DEF it hardly use any without a trailer or with a small trailer (2500 lbs.) behind it. But hook a bigger trailer on it (like 8000 lbs.) and the DEF tank will go down quite a bit faster on it especially if you push it!!

A lot of them do, and all have an acceptable oil consumption rate that is in the manual. Even everyone's favorite Toyotas, Nissans, and Hondas. Inevitable, especially with these ridiculous 0w-16 and 0w-8 oils. Some BMWs are worse than this truck and it is considered acceptable. I keep saying, the solution is to run the special Amsoil 0w-20 developed for this truck. It is thicker than the 0w-20 from the dealership , much closer to a 5w-30 than a 0w-20, and it handles fuel dilution well. It will not burn oil on the Amsoil, or at the very least not as much. The stock oil is 7.8cst at 100c. The Amsoil 0w-20 light duty diesel is 8.9cst at 100c.

That's normal oil consumption industry wide at this point. Toyota and Honda both state their engines normally burn up to 1 quart every 1200 miles, even the sedans and crossover SUV's that don't tow.

[@ktpinnacle]

I had additional transmission cooling installed in my 2001 when I had it built. I've changed fluid diligently and done very little towing though it has done many summer trips in the desert. I'm convinced that the additional cooling is the reason my transmission has lasted 355K miles.

[@ALMX5DP]

Keeping temps in check is one thing, running at 120 degrees is another. I think at that low of a fluid temp, it's not able to adequately provide protection (either from viscosity reasons, friction enhancing aspects or fluid shear strength).

[@MarkSmith-cz3by]

I’ve never seen a transmissions fail due to running at low temperatures, however I have seen millions of transmissions fail, running at higher temperatures GM’s heavy duty, 10 speeds in their 2500 and up series trucks all run in the 140° temperature range with the same exact ULV trans. Fluid as in the half ton trucks. Three-quarter ton truck 10 speeds are required to tow heavy loads, and therefore need to run at a lower temperatures to give proper protection and keep the viscosity of the oil from getting too thin which could possibly cause failure in the bearings and planetary gears

[@ALMX5DP]

@@MarkSmith-cz3by I think that’s because the vast majority retain OEM designed thermostats which keep the fluid at a minimum operating temperature. A quick search suggests that the GM 10-speed HD transmission has a thermostat which opens at 158 degrees, and is spec’d to have level checked when between that an 170. Not sure where you’ve seen that 140 figure, as forums suggest 185-205 is pretty common, even a bit more when towing heavier. I think a GM engineer even said their transmissions and fluid are good to 250+. Of course I’d never want mine to creep up that high but I think that the 170-200 range is pretty common and acceptable.

Thanks for the videos Tim. Get the Def blue jug only if necessary. Every tuck is different. Usage is general and so many variables. Where you are and how you drive and time of year are biggies. Yes, GM needs larger fuel and Def tanks. Generally I drive easier then many people. I get less mileage with mine, but I use far less Def then you do and others I've heard about. The " you are set to driver 2" message you talk about, and being a probable tech issue? No it isn't a tec problem. It's Operator error. To fix that, start using the other key fob. The key fobs are what determines the setting there. Key fob 1 and key fob 2= Driver 1 and Driver 2. Or program it with the easy out button. We love ours. Happy driving.

[@saltyreef3714]

The DEF to diesel usage ratio is 1gallon DEF to 50gallon of diesel regardless of the driving conditions. It is all about neutralizing the NOx that is the byproduct of burning fuel. The ratio is the same unless the fuel quality somehow causes more NOx. Now when towing, more diesel is used because of reduced MPG. Also, the DEF to empty is a calculation that the CPU does based on current average MPG. For example, when I'm towing, the computer tells me 500 miles DEF range. Start driving on normal commute and that range gets twice as long. My setup averages 30.5MPG regular drive and 15.6MPG towing a 6,000lb travel trailer.

Running 15W-40 John Deere Plus 5-2 oil in my 2020 3.0 Duramax. I believe manufactures are pushing lighter weight oils to meet or push epa mileage ratings. I ran it through the winter as well. Ive had zero issues burning oil. I tow with it. Absolutely awesome powertrain. Had similar issue with my semi. They call for lightweight oil from factory. Engine oil weights and quality make a difference. Not at all recommending oil other than what manufacturer suggests.

[@Pickuptrucktalk]

15W-40?

[@hochhaul]

Your engine may have a TSB out for oil consumption. There is a youtube channel called demonworks run by a guy that has owned multiple 3.0 Dmax trucks and has a video about a plastic baffle that GM identifed as causing oil consumption and increased DEF usage. You should check it out if you haven't already.

[@anthonyward4383]

I have not towed yet, but I have put 2700 miles on my new 2023 Chevy 3.0 and have burned 1/2 quart of oil. However, the oil is as black as tar.

[@guygorney3231]

Enjoyed your video. I'm doing early research on the LZ0 for a Tahoe when that engine is offered for the 2025 refresh. I own a 2021 2500HD with the 6.6 Duramax and I tow a 33' 10,000# travel trailer. My 2500 gets on average 12.5 mpg with highs of 15 and lows of 11 mpg. DEF usage is about 1700 miles per tank while towing. Oil consumption is near zero, understanding this is a completely different power plant. All in my experience is very close to yours including the DEF and fueling challenges while trailering. A game changer for me is when I started using the Open Roads app which allows me to use the commercial fueling lanes at most truck stops. So fueling is easy, DEF is right there, you get bulk fueling pricing. After the fees and service charge, I see about a 30 cent per gallon savings. The real benefit is the use of the commercial lanes. A lot of RVers use the app especially the diesel motorhomes. I think the plan is limited to products on the commercial lanes, so no gasoline.

I’ve watched almost all your videos on the 3.0 diesel and recently ordered one partly based on your reviews, my friends experiences and the lifter issues with the GM gassers. After watching your latest video about towing, mileage, def and oil usage I get the impression you have mixed feelings about the the 3.0 now ? Mileage is one of the main reasons I ordered the diesel the def is a small concern but the oil use makes no sense to me-like you said this isn’t 1962.

Nice video. Given that it’s new I don’t expect a lot of issues with this truck and I don’t think you’ve had to return to the dealer for anything. I’d love to see how the engine holds up at 50K miles. It would be neat when you sell it to follow up with the new owner to see how it holds up long term. Perhaps you could consider that. My issue with this truck is bed size - wish they would offer two sizes like the eco diesel did. Thanks!

I bought a new Harley in 2005, put synthetic oil in at first change, 600 miles, burned a quart of oil at 1500 miles. Dealer said run non synthetic oil for the next 1500 miles to allow the rings to seat. Went back to synthetic after that and never burned another drop.

I would like to know what your unloaded mileage is now compared to the OE setup because every mod you’ve done will decrease fuel mileage.

I forgot about the oil usage and it wasnt on the dipstick, i totally forgot about this!:(

[@daves1646]

Hey Tim, Sounds like GM has some compromises with capacities. Made the DEF tank too blasted small, esp since Chevrolet knows the mpg of DEF gets notably lower with towing (run hotter combustion, make more NOx). Fuel economy: 13mpg is decent for >6K trailered, ESPECIALLY for westbound. My gas 3/4 gets about 30% less mpg westbound with headwind vs eastbound. Oil consumption? 1 qt/1000 miles??? No thanks. My old EcoDiesel (ran 15w-40) used NO OIL when towing on 1500 mile travel trailer towing trips. Now with my gas 3/4 ton, I have used 0.5 qt on a 3500 mile trip out west (NY to North Dakota) and back including all local driving. So, not sure GM has any company with the oil use rate.

[@cstgx]

[@edkruzel]

Nice video, very informative. It's kind of disappointing on your mileage, I have a Ram 1500, 5.7hemi, and towing my 6500lbs RV I still get 11.5-12mpg.

[@jbjlock26]

Tim, I have the 2021 Duramax 3.0, so it isn’t a completely apples to apples comparison, but I’ll just share some of my observations… I am towing about a 5,400lb travel trailer, which has more wind resistance than your truck on the flatbed. My normal mpg towing is in the 10-13 range. (24-32 running empty) I have probably between 8,000-10,000 miles towing. As far as DEF usage, I’ve had zero concerns except for my first major trip, which was probably with less than 2,500 miles on the truck. I discount those issues as I think the truck was probably still adapting to conditions. I use a fuel card that gives me a significant discount at a number of different truck stops. The app allows me to search for fuel along my route. I figure at 200-250 miles, I’ll be needing fuel under worst case conditions, so I simply plan that stop using the app. Typically, I’ll top off DEF at the pump every other fill up. (In routine driving around home, DEF lasts many months) The price for DEF at the pump is typically around 4.25-4.50, much less than even Walmart. I’ll go out of my way if I ever need DEF around home and get it at a truck stop. I pretty much never buy a jug anymore unless I am traveling miles away from available truck stops, and towing. Hope this info is helpful!

[@TheBasstead1]

I do not experience oil burning in my LZO. But I did buy and break in my truck during summer of 2023. I have always suspected oil burning in any engine is due to bad rings, bad valve seals, or bad PCV systems. IMHO, bad rings in a new vehicle are due to improper break in, improper clearances during manufacturing, or inadequate part sourcing. Leaking valve seals on a new engine can be improper manufacturing, inferior part sourcing, or improper clearances due to design.

[@hochhaul]

The oil consumption is due to an issue with a baffle that a supplier didn't make correctly and there is an updated part. The oil vapor that was being pulled into the intake due to this defective part is causing increased DEF usage. Even with that issue, it isn't burning any more oil than engines from other manufacturers. Honda and Toyota tell customers that burning 1 quart every 1200 miles is normal for even their small sedans and crossover SUV's that don't tow.

[@JCunningham21]

I did the PPE trans pan only and dropped temps 10deg. i haven't gotten over 185f. Does this truck adjust trans tuning based on temp. Im sure its designed to run 190f as normal temp.

[@Pickuptrucktalk]

The transmission fluid bypass valve really changed the temperature in my truck.

[@JCunningham21]

Isnt the Driver 1 or 2 connected to what key fob you use?

[@Pickuptrucktalk]

[@zr1vetteman09]

A lot of these complaints really point to the reality and fact that this truck isn’t built for regular towing. Nearly all the modifications that he made were to help it sustain safe load leveling and reduced temps generated from working the truck. The DEF consumption alludes to the idea that it’s calibrated to be used mostly empty and to compensate for the increase emissions, it’s gotta DUMP the DEF. 99% of the issues brought up here, including fuel and DEF capacity, load carrying, temp control are ALL resolved by using an HD truck. These are the compromises of a lighter duty truck. After having owned a small diesel half ton and now an HD, i can safely say, even for the occasional towing I do, I’ll still jump for the HD. Better to have a hammer bigger than necessary than to wish you had a bigger hammer. No matter how much mod’s you put on a half ton, you wont increase its GVWR/GCWR. It also will see more wear from carrying heavy loads than an HD. So unless you only tow or haul once a year, a Gas or Diesel HD just makes more sense at least to me. I certainly wouldn’t buy new, pricing of both halftones and HD’s have gone nuts. I recently got a 2500 diesel for 19K with tons of life left in it and i plan to run it indefinitely, even making my own biodiesel if i have to.

[@toddanderson8277]

Great video Tim. This DEF thing seems to be a topic of discussion often in these trucks. I drive a 5.3 gasser and tow a 7,600-pound TT and it tows great and my gas mileage is 10-11.5 fully loaded so not sure if I am quite sold on the baby Duramax yet. Payload looks pretty low on these trucks compared to my max trailering 5.3. For my next truck I am thinking about the 6.6 2500 for what I pull and even if I upgrade my trailer to something bigger, I will still have room for growth. I know people say the 3.0 gets awesome gas mileage when not towing so that is an advantage for sure, but towing doesn't seem to be such an improvement over the 5.3 or 6.2. Love your content and have you purchased a 6.6 gasser 2500 yet or done any testing just curious. Thanks, and Happy Trucking.

[@gcovete1642]

You might want to check the oil burn on this engine. Unfortunately this diesel engine got a recall on the oil turn. Chevy dealer may not reveal this to customers, check other videos on the oil burn. Good luck with your engine. Just be aware... what is oil burn been normal as it destroys your catalytic converter. I have a Hemi and mine does not burn any oil between changes like nothing.

[@karlschauff7989]

lol many guys insist they don't burn oil between oil changes, but when sent to a lab for a used oil analysis they found high levels of unburned fuel by volume. so much fuel that it replaced oil that had in fact been burned. Just wait. There's a reason Stellantis decided to remove the engine oil dipstick from the Hurricane turbo I6 engine. People would have noticed oil consumption. So they ditch the dipstick and just put a digital guage on the instrument panel that will let you know if you need to add oil.

My Silverado with the 10 speed has been in the shop over a week waiting for a valve body replacement for the transmission which is back ordered, and may take several weeks to show up due to the back order and then the uaw strike may have an impact on that too. Dealer told me that the valve body is a common issue on the 10 speed transmissions but after they replace it it’s usually a solid fix, and about 10 percent of customers come back needing a new transmission or valve body again to due to dud part.
