For more than you ever wanted to know about oil, visit the forums at Bob Is The Oil Guy.
There's a lot of controversy over oils. I think German Castol, Pennzoil Platinum, and Shell Rotella are all strong oils. I'm getting ready to try the Bio-Synthetic from RLI. Expensive, but I'm fighting some particular issues that this oil is well-suited to solve.
I think if you want to do more than play roulette with this you have to use oil analysis services, like those from Blackstone Labs or (better) Dyson Analysis.
As to the Amsoil, what I'm looking for there is oil filters, not oil. Certainly plenty of people use their oil and like it.
