Quick question; the great, green state of Washington doesn't have stations that sell anything higher than 91 octane. I have read on the forum that if you mix 100 octane with a half tank of 91, the result is a significant increase in horse power. So, what if I used the octane boosts that are sold in the automotive stores? Work the same? Or would I be adding horrible engine wrecking crap into my car???

HELP!
