I top off my tank of 93 octane with about 2 1/2 gallons of E-85 because it is said to be approximately 105 octane. This will not help the valve seats but it allows me to add some extra ignition advance.



Y probably you probably don't want a mixture with Gas/E85 in over the winter.
Bad things happen with gas/ethanol and winter storage... take it from millions of boaters every where.
This helps some... but not a guarantee the gas won't deteriorate and gum up the carb
