I love both, that's why I have one of each.

BTW, 5W-20 FTW

And Mobile 1 5W-30 is fully synthetic, it's not a semi-synthetic. The Mobil 1 website explains it all.

According to the material safety data sheet in countries requireing full disclosure, (MSDS) its < 30% PolyalphaOlifin. Oil Co's called refined mineral oil synthetic now. Evil BP (Castrol) started this name game in the early 90s. So Synpower, Syntec and M1 in the pop 5w-30 are not synthetic - and some of them have NO synthetic components. Dont trust anyone over 30 ;) and dont trust an oil co to tell you the TRUTH
