I have a 2005 avalanche z71 with 198k miles and a 07 Yukon 212k miles.

The avalanche we believe has worn value guides and it drips some oil on piston while sitting for a while and burns off on initial crank for the day, but doesn't do it all the time. It will use between 1 and 2 quarts of oil between changes.

The Yukon might use 1/2 quart between changes.

I would drive either of them anywhere.

It is what it is.

Inspect what you Expect.

Hunting TN, AL, KY, and IL.
