Just wondering. What's wrong with having your oil changed at the dealer ? On a 3000 miles change schedule, it wouldn't matter what brand of oil they're using, would it ? And at GM you'll get an ACDelco oil filter, at Ford a Motorcraft, and Chrysler will put a Mopar inside, isn't it ? None of which would be a bad choice ? And in case they'll screw up something like breaking your drain plug or losing your car keys, they definitely have the means and parts to get it fixed ?
