A guy I know has a 20k mile TType, he is the original owner and has used Mobil 1 from day one. We got to talking about oils and I mentioned the lack of anti-wear agents in conventional oils today and he got concerned and asked if Mobil 1 has the anti wear agents. I didnt know for sure so I told him I would ask a group of experts that I know ....That of course is U guys. So what do u think does Mobil 1 have the anti wear agents needed for a stock cam or not. Also what is the life span of the Mobil 1 sitting in an engine and started every once in a while---should he change it out after 6 months even if the mileage never gets close to 3k?
