Default Any issues with Toulene sitting in the tank.

I am about to mix 92 Octane and Toulene. But it takes me 1 month to go through a tank of gas (between track events). Can it just sit there mixed with gas? What ratio should I use? (I know I can STFA on that.)

It can sit there just as long as the fuel.

Default I've used a 5 gal drum and topped with 94 = ~101 But, I always used it at the track

and the rest was used up on the way home.

I've heard it can dry things out, if left in too long.

Default Octane level will probably drop over time.

Not sure exactly how much time and how much the octane drops, and I'm not sure whether the environment in the tank will prevent this issue.

Todd @ AWE mentioned to me once that they had a hell of a time tuning a car once. Eventually they traced it to a 55 gal drum of high octane fuel. They had it around the shop for a while, and apparently it was no longer high octane after it had the opportunity to sit for a bit, because the 100 octane straight from the pump fixed the problems.
