     ..... the advise of a GM Mechanic. He said with the Eco Tech LT1 platform he has seen a lot of oil pumps go out when the oil is ran to 10,000 miles .

Along with elevated VLOM failures and brake mechanical vacuum pump failures. 

Cleanliness is important

I've been running Mobil1 since the free changes from the dealer stopped and I usually use k&n, mobil1, or fram filter. I am thinking of trying the Kirkland brand oil on my next change.

0-20 super tech and switching to the A/C delco gold oil filter UPF63R.  I typically change when the oil monitor gets down to 40-30 %

 

i had been using Mobil one filters but they have changed to a shorter design and I like using the longest filter I can find.
