2007 Ram 2500 (Diesel) fuel

Component Fluids, Lubricants and Genuine Parts
Fuel Selection
(6.7L Diesel Engine)Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law re-
quires 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.
490 MAINTAINING YOUR VEHICLE

•Off-road or desert operation.
•Extensive operation at high engine speeds (greater
than 2900 rpm) and loads (greater than 70% throttle).
NOTE:Most vehicles are operated under the conditions
listed for ScheduleB.
NOTE:IfANYof these apply to you then change your
coolant every 100,000 miles (160 000 km) or 60 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
Second is Schedule“A”. It is for vehicles that are not
operated under any of the conditions listed under Sched-
uleB.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level about 15 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.
