Storing race fuel for 9 months. Is it still good?

[tom]

I've had a half empty drum of race fuel in a heated shop for the last 9 months. Wondering if I should scrap it or run it in the turbo?

Most race fuel shall be stored in a dark and tempered room where temps are stable over time. With drum opened It's supposed to be used, racefuel reacts with air and degrades over time. You can store an opened drum for a long time if stored according to spec and you installa nitrogen system to keep air away from the fuel. HAMMER have made up a system that he uses in his drums.

You may mix the old Racefuel with new Racefuel and look at it as a fuel with a lot lower octane.

Be careful the old racefuel could be down in octane. I would hate to see you blow up your engine cause the that fuel is crap.
