How New Biofuels May Put Your Engine at Risk

The August Yachting Magazine has an article on how the new push for biofuels may be harmful to your engine. Read the entire article here.

The diesel fuel you buy today is very likely to be different from the fuel you purchased last year. It is ULSD, Ultra Low Sulfur Diesel, with a sulfur content of not more than 15 parts per million-quite a difference considering that the former low-sulfur diesel could contain up to 500 ppm. Although ULSD is not mandatory for locomotive, off-road or marine uses, your fuel dock will likely be dispensing it since supplying LSD (ignore the unfortunate acronym) to a marina will not be economical for most fuel depots.

Unlike cars, boats are often unused for days, weeks or months, during which a substantial amount of water can accumulate in the fuel. And that's a problem for E-10 fuel, because it is not as stable in your fuel tank as conventional gasoline.
