Ram Trucks 2013 Chassis Cab - Diesel Supplement - Manual (Page 148)

Component Fluid, Lubricant, or Genuine Part
Crankcase Ventilation Filter We recommend you use MOPAR® CCV Filter.
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, No. 2 diesel fuel meeting
ASTM specification D-975 Grade S15 will provide good performance. 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 climatized No. 2
diesel fuel or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will
provide better protection from fuel gelling or wax-plugging of the fuel filters.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel
meeting ASTM specification D-975.
Pickup models, and Chassis Cab models
configured with optional B20 capability, are additionally compatible with 20%
biodiesel meeting ASTM specification D-7467.
