100 oct fuel

[Garrett Brooks]

So there is only 90 oct fuel in the town where I live and my 2011 5.0 runs like crap on it. has anyone ever mixed 100 oct into the lower oct like 90 to boost and not have problems?

I've done it before to boost octane in various platforms. The only thing to make sure is that you're not using a fuel with a vastly different stoich rating than you're tuned for.

I'd buy some Gulf Mach 116 and mix with your pump gas.
