Synethetic oil = huge power gains
 

A guy at a meet last night tried telling people the synthetic oil will give you more power. :fp: A group of us just sat there shaking our heads and laughing at him. He owned a 3rd gen eclipse with a crappy fitting body kit on it. :lol:

it will make you faster if you apply it to the brake discs.

Must be an amsoil salesman ;) Those guys spew the most crap and swear their oil is like the holy grail of things.

If you are switching from crappy dino juice 10W30 to a high quality synthetic 0W20 you'll make more power on a cold engine because it's thinner when it's cold. The fact that it's synthetic is almost unrelated to the gains though. Except Royal Purple, which is apparently magic http://speedtalk.com/forum/viewtopic.php?f=1&t=23709

I run RP in the race car, it appears to make a bit more power. I have not done a back to back dyno and it isn't dramatic. Just enough to keep me paying extra for it.
