Biobor products provide boaters a solution for the fuel issues faced in the marine environment. Ultra-low sulfur diesel and bio-blends plague the diesel vessel operator and the harmful effects of ethanol in gasoline are becoming more and more prevalent.

Biobor JF has been the most widely used marine diesel biocide and lubricity additive for nearly 50 years and coupled with Biobor MD, complete fuel system protection is achieved. Biobor EB provides boaters a complete gasoline-ethanol treatment to not only combat the effects of ethanol, but clean the fuel system and stabilize fuel during storage periods.
