Good information. I'm a "buy the best, American made you can afford" kind of guy. I know people have budgets and they don't always need a $3000 pair of shocks on their 10 second bracket car or titanium rods in a street motor.

But oil is kind of chump change in the grand scheme of things. For some, Mobil One from WalMart might be OK, for others, not so much. I know guys making tons of power with stuff they shouldn't be and it's living, and they're using oils I never heard of until I saw it in their shop. I'm always trying to keep an open mind, get past opinions and learn facts. Not always easy.

If the results don't match the theory, change the theory.
