Bio-Diesel and your engine:
In Europe and in the United States, as well as some other countries, non-mineral oil based fuel resources such as RME (Rapeseed Methyl Ester) and SOME (Soybean Oil Methyl Ester), collectively known as FAME (Fatty Acid Methyl Esters), are being used as extenders for mineral oil derived diesel fuels. Studies show that the use of Bio-Diesel Fuel can help reduce black smoke and lower the amount of hydrocarbons produced by the burning of diesel in an engine, however the Nox levels are higher than that of pure diesel fuel. The use of Bio-Diesel Fuel MAY not pass Local and Federal EPA requirements as well as cause voiding of your Norpro warranty.
Norpro does not recommend or prohibit the use of Bio-Diesel Fuels; however many engine manufacturers do allow a blend of 5% (by volume) of FAME with 95% (by volume) of approved mineral oil derived diesel fuel. Such Bio-Diesel Fuels are known in the marketplace as B5 diesel fuels.
These B5 diesel fuels must meet certain requirements:
The bio-fuels must meet the minimum specifications for the country in which they are used.
In Europe, Bio-Diesel Fuels must comply with the European Standard EN14214.
In the United States, Bio-Diesel Fuels must comply with the American Standard ASTM D-6751.
Bio-Diesel Fuels should be purchased ONLY from recognized and authorized diesel fuel suppliers.
