Well... I must disagree guys
last year at Cal speedway over in Fontucky .... I threw in some Sonoco 98 octane. Just before i did, I was seriously running on fumes. So it was pretty much pure 98. I noticed the added hp probably about 5 minutes after running my G. WAY noticable! Not only was the hp a plus, but that slight ping (detonation) I get every once in a while was totally gone
I'm sure some of you know about detonation
