Message most viscosity changes within the same oil line (usually) have the same film strength rating. I personally run Amsoil, and they are very happy to display their raw data as well as additives on all oils. everything from 10w30 to 0w50 have +-200psi film strength across their HM lineup.
please dont quote me in saying all oils are like this, but it would be fair to assume if a company makes a high quality oil that is listed at the top of the page, they wouldn't cheap out and put a different weight next to the dollar store crap.

5w20 is way too thin for a TT. 10w40 at a minimum. - itsa300zx 11:38:44 02/12/15
