The Cummins® Turbo Diesel engine has been developed to take advantage of the high energy content and generally lower cost Number 2 Ultra Low Sulfur Diesel Fuel or Number 2 Ultra Low Sulfur Climatized Diesel Fuels. Experience has shown that it also operates on Number 1 Ultra Low Sulfur Diesel Fuels or other fuels within specification.
If you accidentally fill the fuel tank with gasoline on your diesel vehicle, do not start the vehicle. If you restart your vehicle you risk damaging the engine and fuel system. Please call an authorized dealer for service.
A maximum blend of 20% biodiesel meeting ASTM specification D-7467 may be used with your Cummins® diesel engine. (Models configured with B20 Capability.)
In addition, commercially available fuel additives are not necessary for the proper operation of your Cummins® diesel engine. However, if seasonably adjusted fuel is not available and you are operating below 20°F (-6°C), Mopar® Premium Diesel Fuel Treatment (or equivalent) may be beneficial to avoid fuel gelling.
Number 1 Ultra Low Sulfur Diesel Fuel should only be used where extended arctic conditions (0°F or -18°C) exist.
