going on a poker run and can only get regular fuel but need high test , any suggestions .

meth injection

Marty starts out with all race gas, then when about half down, fills with the best gas he can get. That gives 150-175 miles of range and you're good. At cruise you should be getting almost 1 MPG.

good idea ted

Think I will have to boost some gas , or else skip one of the stops . Thinking about going slow and stretching my fuel but , never seem to stay that way long enough to be effective .

i guess those auto parts store octane boosters are not worth it?

that s hit is useless,better to mix reg with racing gas as ted mentioned.

The advertising is false with that crap, when they claim it raises your octane 7 points they mean .7 of 1 point and it takes alot of it to even do that when we are talking 100 gallons of gas. Adding race gas, clean tolulene or using Meth injection are the best ways to keep from knocking. A excellent suggestion was made too, start out with 100% race gas, fill up at 1/2 tank and you will still have alot of octane, alot of guys around here do that with there turbo snowmobiles, Smitty

My boat stays on a lift and would be tough to get race fuel to it , I don't trust most boosters they seem to be over rated .

Call Turkey Point, I think they have some kind of deal rigged up for Marty. They put in a tank or something.
