There have been a few threads regarding octane boost products and their ability (or lack thereof) to raise performance. I've got a basic question regarding pump gas.

Here in OH, 93 octane is readily available at every gas station. One brand, Sunoco, also offers 94 octane. There are a few Sunoco's in my area but you have to look for them. In a lightly modified Viper would there be any noticeable benefit to consistently seeking out the 94 gas?

If it's worth a few HP I'd make the extra effort, but it would certainly be more of a pita than pulling into a Shell or Marathon, which are on every corner.

Thanks,

No benefit. Your engine has a certain octane appetite and if it's satisfied by 92, then 93 or 94 or 104 won't make a difference. Also, the higher up you go, the more different the composition and the likelihood it might actually get worse.

I wish that we could get 93/94 octane here in Az. 91 is the best that we can get. I have a couple of cars that would love it, especially a blown car.
