NOTE:
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to operate at colder-than-normal conditions for prolonged periods, use
cli
matized Number 2 diesel fuel or dilute the Number 2 diesel fuel with 50% Number 1 diesel fuel. This will provide better protection from fuel gelling
or wax-plugging of the fuel filters.

Fe
deral law requires that you must fuel this vehicle with Ultra Low Sulfur
