Anyone who uses oil additives may want to check this site out. Some rather disturbing information cocerning Slick 50, Prolong, Duralube, Motor Up and ZMax.

Sounds like they can't find anything bad to say about Synthetic Oils (Amsoil is listed).

I also didn't see anything on their site about TufOil...which I have used and have been pleased with the results. Personally, I wouldn't use additives in a full synthetic though, kind of defeats the purpose of using a full synthetic in the first place, doesn't it.


They also have an engine oil bible that has some interesting info as well:


I would also recommend the Motor Oil Bible ebook. It will tell you everything you ever wanted to know about oil, and hey it's less than $10 d/l. I particularly liked the comparison tests of all the majoy brands. Amsoil tended to do the best, but Mobil 1 and Royal Purple did pretty good as well.
