The Red Line 4-Cycle Alcohol Fuel Lubricant proved excellent lubricity for alcohol to prevent upper cylinder wear and fuel system corrosion. Prevents gelling and corrosion in methanol and nitromethane fuel systems Lubricates upper cylinder and fuel system, increases power with more ring seal Replaces lubrication lost by ''wash'' of dry fuels Not detectable by normal fuel tests, mixes with only slight agitation Use 1oz. per 5 gallons, one bottle treats up to 55 gallons Do not use with catalytic converters
