Description Etha-Guard Plus is a fuel additive that acts to combat ehtanol’s chemical affinity to water or moisture in the air and subsequently damaging fuel systems. By dosing and adding Etha-Guard Plus to fuel tanks, either in use or in storage, you can help prevent moisture absorption and fuel-ethanol separation. Etha-Guard Plus is fully compatible with catalytic converters and designed for owners of future and modern classics to help keep fuel stable in their tanks, who do not require the valve seat protection offered in Valvemaster and Valvemaster Plus. Each 250 ml bottle treats 250 litres of fuel with an incrementally labelled top chamber in the bottle making applying Etha-Guard Plus as easy as solutions get.
