: You are absolutly correct. The additves that they add to Super are there only to boost octane. All gasoline is the same basic stuff cut out from crude oil, the only thing that makes any of it different from each other is the addatives they add to change octane ratings. With out changing your compresion the octane does nothing to improve your engines performance. Even if you run racing(108-120 octane leaded) fuel in a low compression engine it will not improve performance. The only thing higher octane does is reduce pre-ignition.
in a racecar i used to run with a mopar 360 we used VP Purple Racing Fuel. the motor was a stock 8.5 to 1 comp. ratio and when we used the purple stuff the motor would run about 10-15 degrees cooler and we got about 100-200 more rpm out of it....
