  • DEF consumption at record highs, Oil consumption is normal for break in, the oil leak is not normal but I guess I get a free oil change, right ?! SES Light on was fixed by clearing the code, HAHAHA and then the offroad capability is great until you look at the trans temps! Intake modifications have begun as well as a rear differential service with PPE Diff cover.

    I got my 23 Lzo At4 in July of last year. At first it drank the def hard (it also drinks the def while towing). I’m at 16k miles and winters almost over. Will be back to towing soon so standby on that new def consumption rate. But now it’s getting broken in it uses about 1 gallon of def per 1000 mi. I get 27mpg on daily driving to and from work. I live in the mountains and drive about 20mi each way to work. I absolutely love this truck and tows a 24’ 6.5k lbs like a boss. About 15 mpg towing. I bought a qt of oil when the truck was new on the incase it ate oil as has been reported. It’s still sitting in the garage unopened.

    I’ve got a 2024 Trail Boss 3.0 lzo. It’s used one jug of def , 2.5 gallons in 5800km. Mostly city driving and in winter conditions. Had my first oil change and zero oil consumption. Average highway mileage is 6.5/ Litres/100 km keeping it at 100 kph/62 mph. Could not be happier. Towing our 33’ travel trailer (8200lbs) mileage is 19L/100 km double what my 2008 Silverado gasser used to get. No fuss no muss towing through hilly countryside

    I just picked up a 2024 Trailboss with the 3.0 and mine dumped the whole DEF tank on my driveway at 103 miles. Ended up being insulation on the def injector line causing the line to not be clipped into the injector the whole way. It made a heck of a mess in the engine bay, but the dealer got it all fixed up and cleaned. I'm a little over 200 miles now and so far so good.

    My LZ0 uses about 1gallon DEF per 1,000 miles. Average fuel economy over 12,000 miles is 28 mpg. First oil change was down 12 ounces, second oil change was down 5 ounces. No oil leaks, trouble codes or tire noises but mines an SLT with Bridgestone Duelers, 3.23 rear end with a 2-speed transfer case. I’ve added a pair of Westin side steps, AWE bug shield, a dual Banks IDASH setup. Two more additions will be a headache rack and Tonneau cover, otherwise the truck is stock. My truck was assembled in Mexico and seems they did a really good job.

    I’m at 4400 miles on my 23. I’m not using a lot of def. At least I don’t think so. I added 1 2.5 gallon to it and it is still at the full mark. No oil leaks. No noises with the engine. It is very quiet. My oil is still on the full mark on the dipstick. I’m going to change my oil soon. I will bring it to the dealership and get the oil changed when the truck says it’s ready and check the level difference from where I put it with this oil change I do. I love it so far. Going from 8 to 13 mpg with my 21 Denali hd to 23 to 30 mpg in my 23 Denali 3.0 and still pull my 20ft enclosed trailer like it’s not even behind the truck is great.

I trade about once a year due to driving for work, I'm back in a 5.3l elevation couldn't pass up the incentives, miss the 3.0 but don't miss def and oil but I would trade back into a diesel given the option. But an extra $6k off the 5.3 buys me a lot of gas.

    My LZ0 still consumes some oil at 13.5k miles; I tow a light boat (2300 ish lbs) with it and drive it like the boat isn't there so not sure it that causes the oil consumption or not. Also had the oil leak on mine that I noticed around 7500 miles, wasn't so bad that it puddled every time you parked or anything but had a mist of oil under the truck all over the transmission drain pan. Mine is a 2023 LTZ.

    I've been watching your vids off and on since late last year (You made up my mind to buy the baby duramax) Ive had 2 6.6 Duramax's an LMM and an LML, no issues with the LMM, 3 Def tank heaters on the LML. Just purchased a 2024 Sierra 1500 SLT 3.0 X31 about a month ago. Just rolled over 1,000 miles yesterday, I used your install vid for the banks super gauge (running the beta firmware) and pod that attaches to the grab handle, did paint to match. At 1000 miles my Def tank is setting at 77%, so it doesn't appear that my Def consumption is like sky high (I have a 125 hp john deere that goes thru Def like nothing, luckily my 2 bigger ones are older and no def), Regens are starting to get further apart with each passing one, last three were 177, 186, 226. Question is what is everyone seeing on their Banks for ECT, EOT and TransT?? My ECT is running in the 220-225 range, EOT usually about 10 over ECT, TransT 192. (ambient ~75, was warm yesterday, broke a sweat doing a front lift on the new truck!!!). Anyone know if the EOT is actual or a dummy input? Reason I ask is I have a 2007 379 Pete with a Cat acert and the EOT is a dummy reading from the ECM. Thanks again for the good vids, hope you get your new truck issues lined out!!!!!

    @mainelybackroads 4 หลายเดือนก่อน

    2024 Sierra AT4 took it easy for the first 1000 miles so the trans would learn my driving style. Last thing I think about now is the transmission, shifts are so smooth. Regens every 750 miles and uses one bar of DEF on the display. Tank of DEF should last 6000 miles at that rate. It really hit its stride at 2500 miles. Switched to Sport mode and am seeing impressive upper 20's milage. 250 mile trip coming up next week, all secondary roads 45-60 mph, I do a lot of these. Expect high 20's this time, 75 on the interstate gets me 23-24 mpg. I think DEF consumption is linked to the mass of the ZR2's tires, adds load to the motor. Just my thoughts.

    • @jimmyaber5920
      @jimmyaber5920 4 หลายเดือนก่อน

      The transmission does not learn you. It learns shift completion time. There is way too much assumption of big things from things on vehicles described as adaptive or learning. The solenoid pulse width ramp up for the clutch/brake being applied for the upchange and the pulse width decrease profile for a solenoid being shut down is learned on full electronic transmissions. The smooth shifts with the least wear relies on this. The trans computer does not try to anticipate your foot on accelerstor pedal. It does learn the steel plates and friction plate friction changes from wear in and from fluid changes as it ages. The only thing that sort of learns you is a temporary mode that will reduce gear changes if you were to climb a long grade with switchbacks. The normal upshift that occurs when you reduce pedal depression and the downshift when you depress pedal in repetitve cycles will result in trans entering a hold gear mode. When you lift you'd get more engine braking and when you complete turn the transmission would be in the right gear and no up- or down- shifts would repeatedly occur. Once you get to top of grade and not the same grade you can notice the trans not shift up for a brief delay as the decision that the pattern of decel-accel is broken and the normal shift schedule is resumed.

    The issue with the trans temp is not the thermostat or cooler size, it's when the cooling fans kick on. If the truck is at higher speeds, it won't move from 200 degrees. Slow driving, even not aggressive, will see a big climb in trans temp. Need a way to program what temperature the fans kick on.

    • @DemonWorks
      @DemonWorks  3 หลายเดือนก่อน

      You are correct but I will disagree on that as well. The thermostat holds the fluid to 196 and then opens. We have the shutters in front of the engine which spend most of their time closed, so even with the fans on, they will only do so much. In my prior 4 trucks, I was able to keep the temps more controlled, this one is the worst, but I also haven't done anything to help with that, yet.

      @DemonWorks Thernostat at 196 degrees is just fine with me. Needed for best fuel economy. But shouldn't go up much from there. I haven't done anything yet also. My temp has gotten to 236 going 1 miles back in the woods in 1 foot of snow. My raptor would still be at 200 degrees. Idling only seems to raise the temperature which tells me it's not a slippage issue with the trans, but a cooling issue at the radiator. Once them fans kick on, or you drive fast, the temp instantly drops.

    • @DemonWorks
      @DemonWorks  3 หลายเดือนก่อน

      I still lean more towards the blockage in front coupled with the thermostat. The LM2's run cooler than LZ0 engines and the cooling system for the trans was redesigned. I can drive 70mph down the road and still see 210 degrees of trans temp. if that thermostat opened sooner, the temp would not likely climb as high. Compare to the Camaro, L5P duramax and the suv's that run the same trans fluid and camaro/suv with the same trans ... they run 50+ cooler trans temps. The L5P as well, with a different trans and same fluid. Yes, I agree, airflow is what is needed, fans do help, but it's those shutters up front and that thermostat I do not like.@@off-gridengineering3377

    I’ve heard you mention Boost Auto several times. In February of 2019 I bought my 2018 GMC 1500 SLE with the 5.3 new. Wanted tow mirrors but GM said they weren’t available. So I ordered the power folding heated tow mirrors from Boost Auto. Had them installed by my dealer. Lasted less than 2 years. Not worth the $850 plus $600 labor to install. Very disappointed with Boost Auto parts.

    if your engine is consuming oil into the combustion chamber, you'll raise the NOx hence the increased def consumption. Maybe why it tripped a code for the sensor if the Nox is much higher than expected by the computer. Start with that oil consumption issue and your def consumption should go down. It was why it happened on the LM2 because of the baffle issue. I have 24 high country LZ0 @ 7000 miles and i can tell you i havent used/burned any oil and it sips on def. Plus you should check def quality, if its low concentration, it will inject more def to satisfy the pre/post NOx sensors

    • @DemonWorks
      @DemonWorks  4 หลายเดือนก่อน

      I agree it could be related. Every LZ0 consumes oil in the beginning, that’s why they come over filled by 1 quart from the factory. Just part of break in

    My 2022 LM2 consumes about 1 gallon of DEF per 1000 miles. I thought this was normal (in various discussion forums on the internet, people are saying they use about 1 gallon of DEF per 1000 to 1500 miles).

    GM diesels seem to use a lot more DEF than Rams or Fords. My 2012 Ford 6.7L Powerstroke when driven empty would use about 2 1/2 gal. of DEF every 5K-7K miles. When towing a heavy trailer (over 13K lb. trailer), it would use about twice that much DEF. DEF usage is essentially a function of diesel fuel consumed--the more fuel consumption, the more DEF consumption. All that said, your DEF consumption seems excessive.

Most are good, but some are just flawed. Mine has some flaws, I will correct them and move on and prepare for whats next. My channel shares the good and the bad, I try to do that for people in your position, so you can see if the purchase makes sense.

As for "Illegal for dealers to deny warranty for routine maintenance" they can deny claims if maintenance was not performed to the recommended specs (Oil change intervals, Oil weights, synthetic/non synthetic, special required oils and fluids Dex/MERC fluids etc...)
