Okay, so now I'm totally confused. Just recently we replaced the head gaskets in the Cobra. When we got it apart we found two of the roller rockers were in pretty bad shape. Someone who knows more than I do (and that's not hard, most everyone knows more than I ) told me it's because I've been using synthetic oil. He said; "If you use the car on a regular basis synthetic is best, BUT, if the car sits for two or three months (as the Cobra does over winter,) synthetic "drains" too well, and in the crucial start-up period, until oil pressure builds, you're running metal to metal, with no lubrication at all. Mineral oil "clings" better, and will leave a film over the internals."
So now I'm using mineral oil. Was he right? Did I do the right thing?
