I use Mobil 15/50.

Interestingly, Mobil and Amsoil are two of the few oils left that put zinc in their oil, which is totally vital in Porsche air cooled engines. In fact, they have almost identical amounts. Amsoil is as good as any oil, but I still go with what Porsche uses internally.

If Mobil gets rid of their zinc levels, I will likely switch to Amsoil, if they still use the zinc. Or Redline or Royal Purple, if they still use zinc.

I did just look into getting octane boost for hot summer days, and Amsoil has a product which works better than most in some reviews I found, it's worth about 2.25 octane points, so I think I'll try that this summer. Easier than mixing toulene, I think.
