Haven't driven the Mustang since March since we only used it to go to our favorite pool hall & back home. Tank full of 91 ovtane no alcohol fuel.

Started thinking about it..decided to burn off the old stuff. So, made a boring 150 miles round trip on I-5. Ran 4th quite a bit to burn more. Should have driven more, but got tired of it...so only 1/2 of a 16 gallon tank burned.

Actually, the car ran pretty good on 8 months old gas...good performance at full throttle, no pings heard. Maybe because the '08 Bullitt was the first Ford to read octane and deliver timing accordingly,,,car does and will run fine on 87 octane gasahol, but delivers more horsepower with higher octane. So, I pay the premium for the good stuff. Mine is an '09, by the way. Not much difference between the '08 and '09 Mustang Bullitts.

So, 10 miles from home added Sta-bil to treat the entire 16 gallons, topped off with 8.2 gallons of no alcohol 91 Octane. "Pure gas", it's called.

No problems to report, but this got me thinking...how long does it take for gas to go bad? How much more time does Sta-Bil give you? It's all guesses for me...
