Heavy Duty Diesel Manufacturer Fuel Recommendations (Biodiesel)
(Biodiesel is a fuel that can be made from a variety of sources, primarily from cooking oil waste, soybean oil or rapeseed oil).
"Mixtures of diesel fuels with other fuels and liquids, e.g. gasoline, kerosene, ethanol, methanol, and additives (available in the aftermarket, e.g. lubricity, flow, cetane-improver) are not allowed."
CATERPILLAR: Caterpillar neither approves nor prohibits the use of biodiesel fuels. Failures resulting from the use of any fuel are not
Caterpillar factory defects and therefore the cost of repair would NOT be covered by Caterpillar’s warranty.
CUMMINS: "Under no circumstances must gasoline or alcohol be used to dilute diesel fuel. This practice creates an extreme fire hazard and under certain circumstances an explosive hazard."
Additional information will be added later. Detroit Diesel, GENERAL MOTORS, INTERNATIONAL TRUCK AND ENGINE CORPORATION, ISUZU, JOHN DEERE and Others...
