Nice vid, man. The 3.0 duramax is a beast of a diesel for half ton needs. I suspect the LZ0 is even better. Honestly, I can't think of any other motor I would want from any of the big 3 in a 1500.
Man this was awesome. I thought I was on the space shuttle at launch! Lol. This is how you give info on a torture tow test! Great job! Lil Duramax pulls well.
I have a 2022 1500 high country with the max tow package and regularly tow a ATC 2419 gross with all my toys at 10,800lbs. I live in the Pacific Northwest and mainly tow in the mountains and average between 10.5 and 12.5 mpg and I have never had to go below the speed limit except to wait up for a friend towing less weight with a 2007 8.1L. I average 27.5 when not towing, wifes boss has the same truck without the Max tow and gets around 32mpg.
@TheSouders yes, as I said my wife's boss has a 2024 Denali and he gets around 32mpg and my Daughter recently bought a 2023 GMC elevation and is getting the same 32mpg. She just moved across the country to Tennessee and towed a 9000lb trailer and averaged 13.9 for the 2200 mile trip. She does not have the max tow, but I think the extra HP and Torque really make a difference in the 23 and up model.
Dude THANK YOU for clearly narrating what youre seeing, feeling, and where the trucks at at certain grades and elevations. What an extremely informative video. I have this truck, a 2020 sierra at4 3.0L and this videos helping me decide what minor mods i would choose to do to improve towing efficiency for my cross country trips. Cant wait for banks to get that tuner out for us.
I wonder if any of the R&D heads for the diesel engines have ever thought to test different turbochargers on this specific run, because as high elevation that turbo is really what makes the biggest impact….

It would be interesting to see if the PPE aftermarket air intercooler would help make a difference in lowering your EGT’s ? Been thinking about adding one to my 3.0… Nice vid! 👍🏽 Thank you 🙏🏽
I think you are misrepresenting this video with the title. You are stating that you are towing 15000 lbs but that number is your gross combine rating not that amount you are towing.
Awesome video, those temps are really high, surprised the fan wasnt blaring to cool everything down. Overheating is 240 degrees a d 1400 EGT thats like really freakin HOTT i let off on my 6.0 powerstroke if it gets near 1200
Thanks for teh comment! the new truck have fuel control. you can't hurt them, we are testing the systems here. the fan was on full, truck is just that quiet. dont forget it has a DPF so you see higher temps due to the restriction. 1572 is the limp point. teh 3.0 never gets there because of teh ECU limiting fuel above 1,000 ish.
Are those Gauge an app or after market gauge set up? Good video that oil temp is hot, oil boils at 242 degrees, crazy to hear GM says these temps are ok, EGT’s over 1200 are damaging, oil temp that high is damaging I mean I can’t see how they say 320 degrees is ok for the oil crazy.

Thanks for the comment. That is with MX OBD link I highly suggest an iDash instead. It's a full synthetic oil. That EGT is pre-turbocharger they're rated for right around 1600F sustained.
What is true then?? Oil definitely starts boiling as low as 240-250 degrees on the low end and 700 on the high end. Coming form the oil manufactures who produce it… @@firstlast---
@@LeviDill The onset of thermal breakdown is different for every oil. Under high pressure moving quickly through the engine there is no chance oil will start boiling at that temp in those conditions. It won't happen
Not arguing with you. I have seen it boil at lower temps of 300 degrees. Of course every oil is different. Two things that kill motors. Heat and timing.

Thanks for all the Videos, definitely helping me in deciding my next truck to pull my current Travel Trailer at 23ft/ 4600lbs (may upgrade soon to a longer 28-30ft about 7000lbs). Going between the new GM 1500s with the baby Duramax and Nissan Titan XD 5.6 Gas. Know the Titan will tow better but like the Duramax as a great cross between being able to tow my 6-10 times a year but also get great everyday/highway MPG when not towing. Your truck have the 3.23 or 3.73 rear end ratio?
my truck is an AT4 so has 3.23. 3.73 is what I would suggest unless you need 4WD Lo. if you lo range you will be forced to get a high country max trailering as that is the ONLY way to get both.
Does the LZ0 perform better? I am curious how much the additional power helps. It would be nice to pad the max numbers out a bit. I have the LZ0 in a Sierra 1500 and my truck also maxes out at 15,000lbs GCWR
The biggest limitation here was EGT and charge air temp. That’s why his torque never exceeded about 310 when the engine can put out over 450. EGT can’t be helped a whole lot but the charge air cooler and intercooler could be upgraded.
It’s normal to have issues with LM2, high oil pressure and belt problems …, always going at maximum capacity at high temperatures. Users should never exceed %70 of capacity!
When you say your at 15000 lbs, is that what your towing and the truck itself, or just the tow weight? I was planning on towing a 37ft rv with a dry weight of 8500.
Thanks for sharing the info. I am curious to see how the exhaust brake does on the downhill. I wonder if you could have held your speed at 60 going up, if you ran either cruise control or manually selected gears? Thoughts?
No, truck was out of EGT headroom. Once it gets over about 1050 it starts pulling power. The torque request is basically the amount of available power.
Considering this was maxed out and on the hottest day of the year and WOT. No. Wouldn't want to make it a habit but anything under 300 is okay If not ideal.

Honestly EGT are in control due to the ECM limiting power during sustained loads. That torque request (bottom right corner) is the dynamic tuning. Anything under 100 (at WOT) it's pulling power.

@@AndrewVanMeer do you live in a mountainous area? I only had 1,400 lb of payload so do bear that in mind. That only gives you 550 lb for the driver and anything else that you put into the truck.

@@devinsampare9483 I was extremely unhappy with GM. In 2020 they had the secret package called the diesel off-road package and it came with 3.73s and mud terrains. I think they were fishing to see if they would have warranty issues. Suddenly in 2022 Max trailering becomes available. Unfortunately the diesel off-road package also included 4 low, Max trailering does not. However. If you want 4 Lo with a 3 l Duramax and max trailering there is a secret. All high countries come with 4 Lo as part of their whole brand image for that trim level thing. So if you order Max trailering on a high country it is the only way in all of GM to get a 3 l Duramax with four low and Max trailering.
Useable. Wish EGT could be kept lower to keep power up. LZ0 should solve this. Sway, nothing to note, this trailer won't sway unless you get REAL crazy loading it. Power wise is a bit of a double-edged sword on one hand they really gently taper this power to where you're not really going to notice that it's slowly decreasing power. (Whereas on a heavy duty it tends to be very apparent when it reduces power). On the other hand when not doing long passes and just doing sort of medium stuff I wish it would give you a little bit more lead room before it starts pulling power. I should probably clarify I'm not talking about power tanking off of a cliff it just slowly decreases it a couple percent at a time. Bear in mind though I also don't drive like a lunatic and I recognize that I weigh 15,000 lb. I've also always had a loaded trailer that weighs more than the truck. Honestly outside of the mountains from behind the wheel you don't really notice that you're working it hard, so it's really good at holding gears. Mpg and def you know but everything else is relaxing Fun fact I got better mileage on this run than I do towing my 5,000 lb trailer behind my LBZ.
Too much drama, it sounded like you were on a mission to save the universe. I can't believe you freaked out over it shifting to 3rd gear at the end...trust me, everything will be ok!
I just want to be able to tow my 5th wheel travel trailer but I guess I need a 2500 I had one but it broke down now got a 1500 Texas edition 20" tire's I don't know if I can just get better shocks or springs and kind of want to add turbo to it it's a 6.0 V8.
That could be a great motor of GM would of made it a pickup truck motor not a cab over motor which means all the drive components on the front of motor not the back and all gear drives no chains and a gear drive oil pump. Come on GM make this motor right not a second thought motor so the 3rd Gen fix these things and make it a pickup motor and a bad ass motor at that !!!
This is the only way we were getting a half ton diesel. In an ideal world, sure serviceability would have been better, but GM wasn’t going to dump $10M into an engine program at the time. I’ll take it since it turned out to be the best of the big 3’s small diesel options
I wouldn't trust a Daramax after one broke down on me twice on the same day after it took all day to fix just to have brake down again after we got home
Sounds like you got a bad one to start with. If they were all that bad, we would be hearing about it all over the place. Since you are not trusting a Duramax, what is your recommended 1500 diesel setup because both Furd and Dudge pulled the plug on theirs.

Sorry You did wrong you all the max that truck if you would’ve had problems with it damage it the dealership and I fix it. You cannot go buy the sticker you have to go by the Vin number calling the dealership is a sticker is wrong. A lot of people found that out.
the sticker is accurate on this truck. otherwise it isnt what you were sold. then you know full refunds, $20K compensation, false advertising charges, etc. they are feeding BS to TFL.
Yeah, I doubt it if it is a stock 7.3. The 1995 7.3 specs are 225 hp and 450 lb-ft. The little LM2 Duramax is 277 hp and 460 lb-ft and not to mention your 7.3 is going to be in a heavier F-250/350 unless you shoe horned it into an F-150 if it's even possible, so this Duramax 1500 will be walking all over you if you were pulling the same trailer weight. And I failed to mention that fancy 7.3 is 2.4 larger in displacement and making less power. LOL

3.5 ecoboost pulls this hill much better tho and at 2500 rpm.
@@WadeWiggins-eo7bc it does not. TFL's overheated and limped.
@@duramaxadventures5832 post video
Is this truck equipped with max trailering or are you running the highway gears for this test?
There was no 3.0 max towing for 2021. 3.23 gears
@@duramaxadventures5832 wow that’s impressive. I have a 2024 LZ0 with the max trailering and 3.73 gears and have yet to put it to the test.
@@devinsampare9483 I was extremely unhappy with GM. In 2020 they had the secret package called the diesel off-road package and it came with 3.73s and mud terrains. I think they were fishing to see if they would have warranty issues.
Suddenly in 2022 Max trailering becomes available. Unfortunately the diesel off-road package also included 4 low, Max trailering does not. However. If you want 4 Lo with a 3 l Duramax and max trailering there is a secret. All high countries come with 4 Lo as part of their whole brand image for that trim level thing. So if you order Max trailering on a high country it is the only way in all of GM to get a 3 l Duramax with four low and Max trailering.
Does your truck have the air ride adaptive suspension?
no T1 has adaptive suspension
What did you think of overall performance behind the wheel?
Useable. Wish EGT could be kept lower to keep power up. LZ0 should solve this.
Sway, nothing to note, this trailer won't sway unless you get REAL crazy loading it.
Power wise is a bit of a double-edged sword on one hand they really gently taper this power to where you're not really going to notice that it's slowly decreasing power. (Whereas on a heavy duty it tends to be very apparent when it reduces power). On the other hand when not doing long passes and just doing sort of medium stuff I wish it would give you a little bit more lead room before it starts pulling power.
I should probably clarify I'm not talking about power tanking off of a cliff it just slowly decreases it a couple percent at a time.
Bear in mind though I also don't drive like a lunatic and I recognize that I weigh 15,000 lb. I've also always had a loaded trailer that weighs more than the truck.
Honestly outside of the mountains from behind the wheel you don't really notice that you're working it hard, so it's really good at holding gears. Mpg and def you know but everything else is relaxing
Fun fact I got better mileage on this run than I do towing my 5,000 lb trailer behind my LBZ.
Now the 2.8 gone I guess it is baby Dmax
I hate when people call the 3.0 the "baby" Dmax. The 2.8 will forever be the baby dmax. people need to find a new name for the 3.0.
Too much drama, it sounded like you were on a mission to save the universe. I can't believe you freaked out over it shifting to 3rd gear at the end...trust me, everything will be ok!
I was so excited to have power, foot was getting tired from pushing so hard! 😂
I know. I started thinking of the old movie ," Das Boot", where the submarine is diving uncontrollably. Then he hit the pothole and the camera jerked.
Why is he yelling?
I thought that truck could only tow somewhere around 8800 pounds especially for the at4
That's what it's towing. we are maxed out!
Ohh ok I misunderstood. I thought it was towing 15000 lbs
@@santiagoortega92 that's the total weight truck and trailer.
With the Max Towing package that gives it a higher numerical rear gear ratio, it'll tow 13,300 lbs.
I just want to be able to tow my 5th wheel travel trailer but I guess I need a 2500 I had one but it broke down now got a 1500 Texas edition 20" tire's I don't know if I can just get better shocks or springs and kind of want to add turbo to it it's a 6.0 V8.
Trans temp?
It's shown on the left in the video
Don't see it
@@jw8578 bottom left on the 5k video stream of the gauge. 200-ish
very cool vid
I have question what about oil consumption? I am hearing one quart to every 2000 miles, seams alot
that's what GM has decided is "normal" for their product.
The ford trucks use oil I no some do have say they use oil
Unless that truck and truck bed is filled with concrete I am not sure how you are getting 15000 pounds.
@@adamh3272 every thing here is 15k, actually about 300 lbs over when full of fuel.
@@duramaxadventures5832 oh ok you are talking both trucks and trailer. I misunderstood.
That could be a great motor of GM would of made it a pickup truck motor not a cab over motor which means all the drive components on the front of motor not the back and all gear drives no chains and a gear drive oil pump. Come on GM make this motor right not a second thought motor so the 3rd Gen fix these things and make it a pickup motor and a bad ass motor at that !!!
200k service interval on the belt. I'm not too worried about it. Would I like all gear driven? For sure!
Agreed!!@@Derek-pd4fc
This is the only way we were getting a half ton diesel. In an ideal world, sure serviceability would have been better, but GM wasn’t going to dump $10M into an engine program at the time. I’ll take it since it turned out to be the best of the big 3’s small diesel options
I wouldn't trust a Daramax after one broke down on me twice on the same day after it took all day to fix just to have brake down again after we got home
Sounds like you got a bad one to start with. If they were all that bad, we would be hearing about it all over the place. Since you are not trusting a Duramax, what is your recommended 1500 diesel setup because both Furd and Dudge pulled the plug on theirs.
@@billyyank5334 It's all over RUclips people having problems with darmax diesel trucks common fuel problems. Ford, Chevy, Dodge the company's all know about it but they don't want to fix it costs to much or don't know how too fix it.
@@billyyank5334 I wouldn't recommend a diesel setup 1500 the next too the towing of a Duramax Diesel. Is what I have now 1500 Chevy Silverado Texas edition 9,000-12,000 pounds. Maybe a trail boss but I think it's lower then the Texas edition less it's the Duramax.
@@billyyank5334 Some the diesel fuel made the fuel injectors bad and fuel pump. One RUclipsr said he was going to Ford because he was tired of fixing the same thing over and over and the dealership mainly just blames the owners. So they don't have to fix it but I seen the same thing with another RUclipsr on a Ford diesel truck oil fuel problem.
@@SULLIEDASP Thanks. I'll have to do some searching as I hadn't seen anything about that.
What gears in this truck? 3.23 or 3.42?
3.0 is only 3.23 or 3.73.
this is 3.23.
Thanks for the info. I have been looking at a max tow 6.2 at 3.42, so I thought 3.42 was the max tow lackege, but I now see the 3.0 max tow is 3.73. Awesome! Would love that set up on my 3.0! @@duramaxadventures5832
A 3.5 eco boost can do much better then that and it is not even a diesel!
@@richarddubois5529 yep, but this gets 34 MPG at 67mph. 3.5 gets 17mpg
And get rid of the two stage oil pump leave it as a high flow low pressure pump or full pressure all the time. I think it’s a great motor if you will fix these few things and a rubber belt drive oil pump are you kidding me come on you can do better than this !!!!
Sorry You did wrong you all the max that truck if you would’ve had problems with it damage it the dealership and I fix it. You cannot go buy the sticker you have to go by the Vin number calling the dealership is a sticker is wrong. A lot of people found that out.
the sticker is accurate on this truck. otherwise it isnt what you were sold.
then you know full refunds, $20K compensation, false advertising charges, etc. they are feeding BS to TFL.
They literally put the VIN on the sticker… weight ratings are matched to each individual vehicle based on build specs.
My 1995 7.3 liter can beat that !
I would hope so with 4.3 more liters, but the 7.3 is an under performing turd. Reliable yes, but extremely slow.
Yeah, I doubt it if it is a stock 7.3. The 1995 7.3 specs are 225 hp and 450 lb-ft. The little LM2 Duramax is 277 hp and 460 lb-ft and not to mention your 7.3 is going to be in a heavier F-250/350 unless you shoe horned it into an F-150 if it's even possible, so this Duramax 1500 will be walking all over you if you were pulling the same trailer weight. And I failed to mention that fancy 7.3 is 2.4 larger in displacement and making less power. LOL
Pick up truck on the trailer doesn’t wait 15,000 pounds just saying
engine is pulling 15K lbs up this mountain.
You misunderstood, the GCWR of the entire thing is 15k. That’s how much weight that little 3.0 had to move.
