Biobor EB is a specifically formulated additive for gasoline and ethanol fuel blends which helps combat the negative effects of ethanol and conventional gasoline related issues.

The marine environment introduces numerous challenges to boat owners and gasoline engines. Boats can go unused for months at a time, humid environments promote condensation and engines burn much higher volumes of fuel per hour at higher rpm. To top it all off, ethanol-blended gasoline has brought upon its own set of concerns for boaters. Ethanol can lead to corrosion of fuel system components, deterioration of fuel lines and phase separation issues that can be detrimental to marine engines.

Fuel is stabilized for up to 18 months, performance robbing deposits are removed and corrosion issues are virtually eliminated. Additionally, Biobor EB uses a proactive approach to preventing phase separation in fuel tanks by inhibiting the water/ethanol bond, and keeping ethanol in the proper blend and suspension. To combat all of the fuel related issues found in the marine environment with one complete treatment, use Biobor EB at every fill up for a more efficient, better running marine engine.

  • 16 oz. Bottle Treats 240 Gallons
  • Excellent for any 2 or 4 cycle engine
  • Adds lubricity, protects elastomers
  • Prevents fuel phase separation: Ethanol is hydroscopic and has a tendency to bond with water found in the fuel system and fall to the bottom of your tank. This process leads to a concentrated water/ethanol layer at the bottom of the fuel tank (where most fuel pick-ups are) and a loss of octane rating in the remaining gasoline layer. When fuel is then used by the engine, excessive knocking can take place, incomplete combustion and worst case, detrimental failure of engine components. Biobor EB helps prevent this ethanol/water bond and keeps the ethanol molecules in the proper suspension while allowing any excessive water to be removed through filtration.
  • Cleans the entire fuel system: As a byproduct of the combustion process, carbon deposits are often left behind on intake valves and other internal parts. These deposits are commonly the source for loss of efficiency, power loss and reduction of performance levels. The detergents in Biobor EB effectively remove and prevent deposits in the fuel system and keep varnishing and gums from accumulating in carburetors and other internal components, resulting in quick start and a more efficient better performing engine.
  • Full corrosion protection: Corrosion is always an issue in fuel systems and components are even more susceptible with the use of ethanol-blended gasoline. Biobor EB has been consistently proven by industry testing to prevent the formation of rust and corrosion on metals commonly found fuel systems.
  • Stabilizes stored gas up to 18 months: Gasoline can begin breaking down in as little as 30 days, forming gums and varnish that can damage engine internals and render fuel unusable. The oxidation process of gasoline is in fact expedited in ethanol-blended gasoline. Varnishing of piston rings and carburetor internals are often the most common victims of old, stale fuel. Biobor EB will stabilize fuel and keep it fresh for short term storage or up to 18 months.
