I've only only seen 91 octane fuel in Utah until today. There's a station on Redwood road between 5400 S and 4700 S that has Sunoco racing fuels. They offer 100-105 octane fuel. I'm unsure of the price though....Prolly don't want to know.

 

Wooooo man, I bet it's going to be over $3 a gallon. I have a friend here, he just came back from Tokyo Japan, he lived there for 4 year, and he told me that they have those high kind of octane fuels there. Always 100-105. Yeah their cars require that kind of fuel all the time.
Well overhere on Oklahoma the highest I use is 94. And that's actually the highest I've ever seen here.

 

Where the heck did you find 94 in Oklahoma??? We only have ONE station here in Norman that sells anything more than 91, and that's crappy Sinclair 93.

 

It would be interesting to see the 1/4 mile gains to be made with say 105 octane and a 19-21 deg advanced timing.
