This thread is exactly why I don't post in threads like this (usually).
I have not seen a single comment where oil was dyno tested, correct evaluated and then compared to another oil. Why is that? Because it in farking expensive to test oil correctly. To test an oil against just one other oil takes 30-40 dyno pulls, at least 3 (sometimes 6) oil changes (if the data is unexpected) or more, the cost of analysis, then, disassemble and measure component wear.
So let me say this about the 6 different oils I have tested. Dino oil is usless in a performance engine. I don't care how often you change it. Synthetic oils do not stop lifter rotation, any more than they stop roller lifters from rolling. Total crapola. If using flat type lifters you MUST have ZINC. PERIOD.
As for cost, the bottom synthetic oils are worth slightly more HP over dino oils. The mid priced sythetic oils are a waste of money. The uber expensive oils (such as Torco and LAT) are worth every red cent. They out perform every other oil in testing and after dyno results (there are a couple more in the uber class that are good too).
Do what you want, but asking a forum what oil they like is akin to asking what ice cram is better, chocolate or vanilla. It's mostly just opinion or taste.
FWIW, mocha almond fudge is the best ice cram.
