i get 100 octane avgas from my local airport, for (current price) $4.45 per gallon. grab a tank of that, and see how you do. avgas is a hell of a lot cheaper than race gas is.
Airport is 10 mi away,been running it since 1992 !!
mine is 1/2 mile away, and even has "pay at the pump". been using it since 2000.
