    You have 2 VERY stupid mechanics. Every time I purchase one of these GMT800s first thing I do is run some oil flush, throw on a crap oil filter and dino oil drive for 100-200 miles, dump oil, replace that $3 oil pump o-ring, oil pan gasket, oil filter adapter gasket, replace with GOOD oil...

    Thinking of Buying a 07-14 NNBS Tahoe/Suburban? Look Here

    And I STRONGLEY recommend sticking with full synthetic motor oil with these LSX engines and our bi-polar weather across the country !!! Blend and Dino oil(if you can still find any) I would leave for the winter beaters out there lol

    Not sure your budget?? but a DOD delete is $$$$ !!! First step I would get a Range disabler on Amazon Once you go with DOD delete I would stick with Texas speed on camshaft/lifters Dave

    What Oil To Use in My 6.0 Denali

    If you havent done your oil pick up tube seal Fel-pro # 72401 I HIGHLY recommend it !! Cost under $3 right now on Amazon and you have to drop oil pan and pickup tube to replace it. But better do it now then when it fails and take out your oil pump !! My 2001 with 200K mile was HARD like a rock...

    What Oil To Use in My 6.0 Denali

    Yes it's one of the most TOP RATED filters out there !! I run the XG3675 on my 01 burb with 2-3 4000K OCI's on it. I would NEVER run ANY filter pass 10K miles !! IMO a $10 filter is not worth passing "trash" into your $$$ engine !!

    His is a 2006 and it DOES NOT require Dexos !! Dexos is for 2011 and newer GM Vehicles I was taught this at GM service dept I worked at few years ago and this story in cars.com backs it up https://www.cars.com/articles/what-is-dexos-oil-2-422608/
