Actually it's a proven fact that synthetic oil has an effect on engine output. Sure it's a small increase, but it still exists nontheless.

Then I must be going crazy because I never felt a difference like this. Ask almost anyone on this forum if they feel a difference when they switch to synthetic. They most likely will say yes. If its all in my head, thank god, cause at least it makes me feel better swithing to it.

Royal Purple FTMFW! Mobil one is not a true synthetic, they use ultra-refined petroleum based stocks. Still I would go with Mobil 1, Royal Purple, Amsoil, Redline, or *German* Castrol oils. The difference is not in the guys head. Synthetics reduce internal frictions on parts, allowing them to move freer. The was a test using Royal Purple in a motor, tranny and rear diff and it got a couple of ponies out of it. Can't remember how man, but it was enough to make a difference. Synthetics are just naturally better all around for motors, trannys, and diffs.
Leo, is yours a tC? I know the tC can only use Toyotas ATF due to them creating it specifically for their transmissions. It last over 100k per change and if you use another brand/type, you will void the warranty on it according to the dealership b/c no other type of ATF is to be used due to slippage and other stuff.

I myself belive only in Mobile 1 synthetics. If Porsche, and Mercedes use them from the factory then it is darn well good enough for my toaster. *two cents*

Why would thinner oils not be recommnded for lower temperatures? Thats what they are partially designed for.
As far as your M1 comment, you cant go but what other manufactures use. You have to go by what your engine tells you it likes and you do that by having a used oil analysis. That said, M1 shows higher wear numbers than Penz Platnium in the xBs motor. There is nor one-size-fits-all answer to the question of what is the best oil.
