I mix 1 gallon of methanol to 1 gallon of E-70. It tests out to 85% alcohol, 15% gas.

As long as you tuned your combo for the mix, it is not an issue. But if you put 85% ethanol into the car, you would need to lean out the carb 10-15% (since it was tuned for the methanol mix).



Jim, Yes it is tuned for the mix.
