ETHANOLMATE is the leading product for use with ethanol-containing petrol. It is a corrosion inhibitor, fuel stability improver and biocide. Added to the tank when re-fueling, ETHANOLMATE helps prevent fuel degradation in storage - guarding against fuel system corrosion due to the increase in acidity when petrol containing ethanol is stored e.g. over winter. ETHANOLMATE is fully endorsed by the BHVC - please read the BHVC Fuel News link in the product description.
