I posted this link in December showing a link to General Motors web site for dealers service departments. I zeroed in on C7 information that service personnel use.

Included in this information is the correct oil filter for a C7 Z51 application. The correct filter is NOT the PF64 listed in the Owners Manual. The site states "Z51 Oil Filter Replacement - This engine uses a special high performance oil filter, UPF48R or equivalent. Use of any other filter may lead to filter failure and/or severe engine damage".
I do my own maintenance so I will be using this filter on my Z51. I have not gotten underneath the car yet to see what oil filter came from the factory.
My question is: Has anyone changed oil yet on a Z51 and what oil filter came on the car?
Question 2: Why is there no mention of this in the owners manual?
In a recent thread people are talking about using after-market oil filters for the track. After reading this I would be concerned about that.
