Thanks Grumpy, what sucks is that oil had less than 2k on it so "toasted for some time" makes me say YIKES! GM Delco installed at dealer for oil consumption test.
You know what I have in it now and just passed 500 miles to drop filter, but tore right pec yesterday so everything is on hold.
Air filter has since been cleaned and oiled (RotoFAb)
Very saddened by how this engine is turning out, wifeys old Escalade had a 6.2 140K when we sold it, never any oil consumption to speak of etc.
After I dump this oil I will switch to some high dollar stuff and am planning on the AutoRX with each oil change for the next couple years.
Of course I have 10 quarts of Kirkland 5-30W dexos and 5 quarts of Supertech 0-20W on hand ....lol
Who could have guessed all this $$ for such poor quality, this truck was the most $$ I have ever spent on a vehicle I am 58 years old.
Blah blah
Thanks again for sharing your knowledge and input.
