FUEL AND ENGINE MIXING OIL
Mix oil with the gas at the ratio specified below.
Always use fresh, name-brand gasoline, and
mix the oil and gas the day of the race. Do not
use premix that is more than a few hours old.

If knocking or pinging occurs, use a different
brand of gasoline or higher octane grade.

clotting of the oil could result. If you wish to
change oil types, be sure to drain the fuel
tank and the carburetor float bowl of old pre-
mix prior to filling with the new type.
