Red Line alcohol fuel lubricant is designed to prevent gelling and corrosion in methanol and nitromethane fuel systems while providing lubrication lost by the wash of these 'dry' fuels. It lubricates the upper cylinders and fuel system and increases power with improved ring seal. Prevents gelling and corrosion in methanol and nitromethane fuel systemsImproves piston ring seal for increased powerReplaces the lost lubrication of dry fuelsNon detectable by normal fuel testsRed Line alcohol fuel lubricant should be mixed with fuel at a ratio of 1oz to 5 gallons (19 litres) of fuel, 1 bottle treats up to 55 gallons (208 litres) of fuel. Alcohol fuel lube is not detectable by normal fuel tests and mixes easily.Please note: Alcohol fuel lubricant should not be used on vehicles with catalytic converters.355ml (12 fl oz) BottleTechnical Data Sheet
