Correct Oil Filter?

I had the exact opposite experience. I was going to change the oil myself until the parts guy that I know told me it would be better for warranty purposes to have the dealer do it,so they have a record of it. The old story about denying engine coverage applies. Anyway the service manager said to ask for a journeyman to do it, and I told him I had the filter and oil already. He said not a problem to use my stuff. I told the service writer to make sure the tech drained the oil cooler when he changes the oil. In about an hr they came and got me, said the oil & filter were changed along with draining the oil cooler. Then he tells me the tech drained my catch can. Wow. Then they give me the invoice for $35. No complaints here
