Motor oil question

Mobil 1

I don't think so.......

I am guessing that each dealership uses whatever they can get the best rate on. So figure valvoline or castrol or something like that. I sort of doubt there is a standard dealership oil - from their owners manuals, anything which meets the specs they outline there should be just fine - so for an L300, as an example, any 5w30 (with the API, etc. certifications) is just fine. I use Mobil 1 in ours.

If I was guessing, I'd guess GM dealers use Goodwrench Motor Oil.

The 2001 SC1 I bought last month had a valvoline sticker on it. Bought it from a Saturn dealer.

Probably the former owner took it to an oil change place. Was the mileage close to the same mileage as when you purchased the car?

My local dealer is using the Castrol line. Have no idea about the factory.

My Saturn dealer's service also uses (or has used -- I haven't taken a close enough look at the sticker recently and I'm too lazy to put on my coat and go outside to the parking lot to check ) Valvoline stickers. Steve
