High Octane Gas?

[jbashaw]

Would there be any benefits to running high Octane Gas and Octane booster if I was to advance the timing just a degree or two? Or however it works retard it a little? Would you see any gains in power or mileage?

dont use the bottle octane booster.. no need.. higher octane gas is ok if you advance timing a bit to like say 12* btdc.. but in a stock app.. i'd just leave it be put the cheap fuel in and run it...

You'll get more power by running premium fuel and bumping your base timing to maybe 12*

But usually not enough to be worth it.
