Mystery Oil Loss - Where is the oil going? 2008 Yukon Denali
This is good information. After reading through all this, here's my thoughts. 1. Checking hot will have a higher level as all things expand when hot. This would explain why it appears lower when it cools off. 2. @rdezs has a good speculation on the oil getting whipped up. Is it possible...- B-train

PS Fluid Flush Quantity
Just get the Lucas PS fluid from Walmart if you want to make it easy. Buy 3 so you have extra if you spill some or choose to run more through it. It really is probably one of the easiest fluid exchanges you'll ever do.- B-train

PS Fluid Flush Quantity
I too have done this and seen many other do it. It definitely works just fine. I'd be curious to see what the differences really are between the two. It seems as if the PS might be a little thicker, but not by much.- B-train

PS Fluid Flush Quantity
I just did my 2008 with 2 quarts of Lucas PS fluid. I bought 3, but didn't need the third. It was super simple with a second set of hands. 1. Pull off return hose from pump (spring clamp connection) and direct it to an empty 1 gallon jug. Put cap on pump connection tube (prevents leakage when...- B-train

Air Cleaner???
No disadvantage to running the deeper filter. There's more surface area to breathe through, so in theory it will breathe easier and stay cleaner longer.- B-train

Rumbling sound
I agree with @Blackcar. It had a similar experience with the 8 speed in my 2017. Felt like rumble strips under certain conditions. A tranmission flush with new fluid fixed it. I think it was for the 8 speed only? Do you drive in AUTO 4wd? If so, put it in 2 HI and see what you get. Using...- B-train

2018 Tahoe premium adaptive cruise control downgrade to standard
I'm not sure on this, my guess is you would need access to the BCM to toggle off certain options. We have it on our 2017 Denali and I absolutely hate adaptive cruise, so I rarely use it. If you keep your radar distance short and then drive like a semi driver and change lanes well before you...- B-train

Onstar Not Working
Call me crazy, but a factory failure of On-Star seems like a blessing.......for those of us who don't want big brother riding shotgun. I've disabled my 2017, and I'm not sure if my 2008 still works, but will remove that possibility next time I'm in the mood to take apart the dash. If your...- B-train

Fuel System
As @Fless stated. Another thing to consider is if they were rusty, you may very well have disturbed the fragile rust particles holding hands and now have a pin hole leak somewhere. If it's a TON of fuel, then I'd go with missing/cut o-rings as the probable culprit. No goo or sealant will hold...- B-train

The Adventures of Sylvester, the 2018 Suburban 3500 HD
For the short time I had a Denali XL I loved it for road trips. All the extra room behind the rear seats was fantastic. And.......the extra exhaust growl that the XL has over the standard wheelbase is a plus too. My mom was riding in the back on a trip to FL and even commented on how nice it...- B-train

Looks awesome! I'm super jelly..... What kind of mpg does that thing get? Have different tires made any improvement over what you ran before?- B-train

What brand name oil
This is going to get all opinions from all angles....... Personally, I run a high quality 5w-30 full synthetic. I get mine from Reladyne - Duramax Full Synthetic. It has good quality base stocks, good quality additives, and rates well on the oil standard tests. Bought in bulk, I can get it...- B-train

8L90 Thermostat bypass
I have the same transmission and was going to do the same. I bought a kit that advertised it did both the 6 and 8 speeds. I asked my friend (master GM tech of 35 years) about the longevity of the 8 speed with heat failure vs the 6 speed. He said they are really good transmissions once you get...- B-train
