thanks was hoping to find it at a gas station near the house going riding tomorrow and dont have a gas can at work with me. I remember a gas station in thomasville had it when I was in high school but it has changed hands sence then.
I know this works as my past car, Buick GN, was very particular to octane & what boost level you could run with a given octane. Xylene is the main ingredient used in F1 fuel & works out to be 114 octane by itself.
Here's a discussion on it. http://www.ls1tech.com/forums/fueling-injection/70889-xylene-mixed-gas.html
