Thanks for posting these Chris ...... you are starting to change my mind regarding oil change intervals although that would certainly hurt my business.
What is one of those oil sample reports worth over there?
The biggest concern i have regarding extended oil change intervals is a history of seeing used Jap Imports (or lazy kiwi car owners) that don't have regular servicing coming though the shop with sludged up engines.
depending on where you have a sample done its between 25 and 35. Amsoil and Oil Analyzers actuay just came out with a basic kit that shows bare bones of the test. its 14$, but doesn't show much IMO.
what's your main focus of the business. cause if repair side of things I've seen offering extended drain intervals with the right oil, help grow a faith from customers saying "look they aren't trying to nickle and dime me, I'll take theyre repair suggestions serious, and have them do it."
and yeah that's the only issue I'd know of in a marker like yalls, poor previous owner maintenance. its worse there than here, and its pretty bad here..
