    6.2L - Debris Found in Engine Oil

    Agree with the others on both accounts: 1) My experience with my last two Tahoes has been the oil consumption stops (or drastically decreases) when going to a 30 weight oil; and, 2) I would be documenting the heck out of the pieces you are finding in your oil and would make sure the dealership...

    Driver side mirror issue

    My fix was to turn off the entry/exit seat function so that the mirrors and driver seat stay in the same position. It's not actually a "fix," but at least I'm not having to readjust and guess where my side mirror should be every time I get in the vehicle. I agree it's very frustrating on such an...

    I got my 25 High Country today

    I don't know whether OP financed through the dealer or not. However, I met a used car dealer years ago who told me he placed trackers on the cars he financed so that they could be found if repossession was necessary.

    fuel mileage

    I get about the same pulling a Kawasaki Mule on a 14x6 open trailer and when pulling my airboat trailer - both packages weigh in the 4,000lbs range. Like has been said, it's more a product of the wind drag than the weight of the trailer. I towed the Mule trailer empty once. With the rear lift...

    Buying 6.2 engine vs 5.3

    I think you have answered your own question. You liked the peppiness, so get the 6.2. If you didn't care about the peppiness, get a 5.3. The 5.3 probably gets the nod in terms of lower percentage chance of issues, but both can have issues. I had a lifter eat into the cam shaft on my 2003 5.3. I...

    Thinking of selling my new 6.2L Denali...

    The oil consumption on mine (both my current 2021 and my 2015) went down to almost nothing when I switched from 20 weight oil to 30 weight Amsoil. I am in Florida and my mechanic is adamant that 20 weight oil is too light for our heat.

    Thinking of selling my new 6.2L Denali...

    No offense was taken. I agree that if I weren't using Amsoil Signature, I would be changing my oil either every 3k miles with conventional oil or 7,500 with Mobil 1 synthetic. I may do a blackstone analysis some day like someone suggested but it is hard to find the motivation to go through that...

    Thinking of selling my new 6.2L Denali...

    It's 30w oil. I'm not recommending anyone do what I do; I simply stated what I do. Everyone here is empowered with the ability to do their own research and draw their own conclusions. There is lots out there on Amsoil Signature Series. Agree or disagree with information available, hopefully...

    Thinking of selling my new 6.2L Denali...

    No typo. It is Amsoil Signature Series synthetic designed for 25k highway miles. I change at 15k for combined driving per my mechanic's recommendations.

    Thinking of selling my new 6.2L Denali...

    I've got the 6.2L in my 2021. It has 93K miles now with lots of towing. I love the engine and (knock on wood) haven't had any issues with it. I run Amsoil and change the oil every 15k miles. I personally would not be trading your vehicle in because of those concerns, especially with no signs of...

    Used 2023 Yukon Denali with 25k miles on it

    Sounds like a good find. If you don't mind me asking, why are you moving from the BMW to the GMC? We have a Tahoe and are considering an X5 for our second vehicle.

    Used Yukon XL Denali advice?

    I've got 85,000 miles on my 2021 6.2 and about 15,000 of those miles have been towing. I run 30w Amsoil oil and at least 91 octane. Zero issues. I think it's a great engine.

    2021 MagRide blown strut

    For what it's worth, I just had all 4 of mine done for about $2,800.00. In my experience, you can get far better pricing at independent shops than at dealerships.

    Long Haul with boat

    Thanks this is good information. I may have to give one of these diesels a try...

    Long Haul with boat

    Do you mind sharing the type of boat? I'm mainly interested to hear if it's a bass boat style where there is virtually no wind resistance or something more like a center console that rises above the vehicle and has some wind drag. 17.5mpg if it's something with wind drag is excellent. However...
