I don't have proof that I have performed regular service. I keep everything on a spreadsheet, miles and what was changed, but I'm not sure they would count that as proof.Anyone who does not have regular proof didn't perform the oil changes. Heck most places these days keep track of your receipts and if you go to the same place, most people do, they can look up your receipts!
So if someone does everything themselves, you don't have proof of service.
