Can I use ethanol blended gas in my Volvo Penta engine?
Volvo Penta gasoline engines may be operated using gasoline blended with no more than 10% ethanol that meets the minimum octane specification.
Fuel containing 10% ethanol is also commonly referred to "E10."
Users of ethanol-blended fuels must take additional care in the maintenance of their fuel systems. The effects vary depending on the fuel tank material. Most boats produced the last 20 years have fuel tanks constructed of aluminum, stainless steel, or plastics.
Since ethanol-blended fuels attract and hold moisture, ethanol content can contribute to causing corrosion of tank material in aluminum fuel tanks. Corrosion material can clog fuel filters and damage injectors, carburetors, and other fuel system components.
Stainless steel and plastic fuel tank materials are not affected by ethanol-blended fuels. However, ethanol-blended fuel can act as a solvent, loosening and washing old deposits or contaminates into the fuel system.
Fuel system or engine damage caused by contamination from water, foreign particles, sludge, or gums entering or forming in the fuel system is not covered by the Volvo Penta Limited Warranty.
