Rear end oil change
Lots of misinformation about the limited slip additive and what its purpose is. Again, truck and suvs DO NOT have a limited slip differential!- Z15

ATF Lacks Cleaning Detergents
The concern of using an ATF in place of a flush is chemical incompatibility with engine seal material. ATF has been known to over swell engine seals and cause leaks and premature failure.- Z15

Oil change proof question...
You got to read the fine print in these extended warranties. Most don't realize this they are really not warranties BUT Service Contracts which is usually stated right in the paper work. They can put any loophole in there they want and you agree to it by making the purchase.- Z15

Rear end oil change
Although the G80 in trucks and sport utilities uses clutches, it is a full locker. If you use a friction additive this can reduce torque / load carrying capacity and is not recommended. IT IS NOT A LIMITED SLIP DIFFERENTIAL. those are typically installed in performance cars such as the Camaro...- Z15

My Yukon Denali 2022 dead battery second time !
I agree with above, don't start it and let it run for 10 min. It could take up to 30 miles or 15 min of city driving to replace the juice used to start it. I put one of these on my cousins Jeep Cherokee. Takes 5 min to hook up. She drives about 3,000 miles a year and it sits for weeks and goes...- Z15

Truck Stuck in Purgatory
Maybe because it was NOT ordered as a sold order it has low priority? Don't really know but sold orders have the highest priority and even then it takes a long time to arrive. Its only been approx. 2 months. All the logistics is understaffed and all these train derailments and there was one in...- Z15

2022 Tahoe w- 7950 miles dead in the road
They have contracts with dedicated trucking company's to deliver parts to the dealer and they will not send Fedex or UPS. Many parts are there the next day but some parts are not inventoried in all distribution centers. For instance when the lifters failed in my 6.2L they had to wait till the...- Z15

2022 Tahoe w- 7950 miles dead in the road
Unfortunately GM does NOT care about the individual customer who is just one small spec in their vast kingdom. They pass that on to the dealer and very few dealers give a rats arse about the customer. The salesmen earn bonus's for selling and the service managers get bonus's for reducing...- Z15

2023 Tahoe Premier Does Not List DFM on the window sticker
My point was not that they did away with, but that they don't blatantly advertise as they did in the past. Probably because of the bad reputation of DFM engines. According a friend who is in parts at local dealer, they stock all parts to R & R the lifters and its not uncommon for them to see 1...- Z15

Friend is considering buying one from dealer inventory and looking over the window sticker, no where does is mention Dynamic Fuel Management (DFM) nor does is says Not Equipped with DFM. They seemed to have made a conscious effort to downplay DFM? 2023 TAHOE 4WD PREMIER EXTERIOR: BLACK...- Z15
