Biobor EB gasoline ethanol treatment is for all gasoline and ethanol blends used in any 2- or 4-cycle engines. This formula helps prevent ethanol/water bond and keeps ethanol molecules in proper suspension while allowing excessive water to be removed through filtration. Biobor EB stabilizes fuel and keeps it fresh for short term storage up to 18 months. It cleans and helps prevent carbon deposits left behind on intake valves and other internal parts. It helps keep varnishing and gums from accumulating in carburetors, resulting in quick starts and better engine performance. Biobor aids in the prevention of rust and corrosion formation.
