Re: Fuel mix for my 69 Camaro L78
Stay away from the "airplane fuel" if it is true airplane fuel it has alochol in it and it will destroy your rubber parts in the fuel system....not to mention it is hard on the aluminum parts too.
For street driving I agree with Sean70ss run a 20 percent or so mix of good fuel. This will help with part throttle detonation and help lube the valve system. Don't tell Rob but there is positions on the throttle other than idle and WOT. With a properly working vac. advance and low octane fuel even 9 to 1 compression engines will spark knock under the right loads.
Just a thought, spark knock, detonation, ping or what ever they call it in your area, could be listed by the surgen general as a almost silent killer of your high compression engine.
