Re: Gas confusion
Pretty sure federal mandate is a minimum 10% ethanol nationwide. I haven't seen non-ethanol blend anywhere in the midwest for a long time. As for regular, premium, etc., my stock '70 350 has 120k miles and runs fine on 87 octane. I would avoid E85 and others blends that are more than 10% ethanol. Although those are usually less expensive, you're milage will be lower, and the added alcohol can cause problems.
