I hear ya Pete, I've done lots of research and dealt with lots of people who had religious convictions about motor oil. I maintain a handful of racecars for people and seen every sort of failure you can imagine. If I had to boil all this down to a few things that people should keep in mind it would be simply -- thin oil isn't good for racing (or really high rpm driving), if you change your oil often enough it doesn't really matter what you run (unless it's too thin), if you think an oil is the best thing ever, then use it, change it often enough and don't run anything too thin and you'll be fine. I've got a chassis dyno and these claims that a given oil makes HP are hogwash, if the oil is at the same temp and was the same viscosity I've never found a difference. Yes, thicker oil costs a few HP, but if the motor lasts longer who cares? Oh and it's better to run a little too much oil than not enough. (Except in a dry sump) Oh and another cool fact. Mobil 1 would be clear if they didn't add color to it! Ok, that's what I've figured out about oil.
