432 TECHNICAL SPECIFICATIONS
Fuel Selection
Use good quality diesel fuel from a reputable supplier in your vehicle. Federal
law requires that you must fuel this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the
emissions control system.
For most year-round service, Number 2 Diesel fuel meeting ASTM
sp
ecification D-975 Grade S15 will provide good performance.
If climatized or diesel Number 1 ULSD fuel is not available, and you are
operating below (20°F/-6°C), in sustained arctic conditions, Mopar®
Premium Diesel Fuel Treatment (or equivalent) is recommended to avoid
gelling.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel
meeting ASTM specification D-975. Pickup models configured with optional
B20 capability, are additionally compatible with 20% biodiesel meeting ASTM
specification D-7467.
