Should I put about 2 oz. of pure casor oil into the gallon fuel bottle I have?
Matt,
4 oz. of castor oil will bring your gallon of Omega fuel to 20% total oil...
Yet, for this engine you would want at least 50% of that oil to be castor... These 4 oz. do come close, but no cigar...
For your next gallon of fuel, shop elsewhere, unless your LHS can bring you the fuel your engine needs; like Sig Champion, or PM GMA.
