The issue is that if you have an engine/motor tuned or rebuilt to have high compression can cheaply convert it to E85, then by running on E85, and not having to buy Race Gas or octane enhancers, save lots of money. Or if your State emission laws have ruled your hot rod, outlaw again change over to E85. My engine conversion cost me just £33.97 that's a full carb rebuild kit, two main jets and two idle jets.
