REGARDING FUELING OF EARLY BUILT 2007 RAM TRUCK CAB AND CHASSIS (DC) VEHICLES.
SUBJECT:
Fuel And Fuel Filtering Requirements For Cummins 5.9L And 6.7L Engines
OVERVIEW:
This bulletin involves a discussion regarding fuel system requirements.
MODELS:
2006 - 2007
(DH/D1/DC)
Ram Truck (Heavy Duty)
NOTE:
This bulletin applies to vehicles equipped with a 5.9L High Output or a 6.7L Cummins Turbo-Diesel Engine (sales codes ETH or ETJ respectively)
that were built on or after March 07, 2006 (MDH 0307XX).
DISCUSSION:
Current Fuel Systems:
-
For the diesel engine system to operate at its peak performance a high level of fuel quality must be maintained. Emission control and fuel delivery
systems have advanced significantly. Care must be taken to insure that the fuel that is delivered to the engine fuel injection system is of the highest
quality possible and free of contaminants.
-
Significant components to fuel quality are: the initial quality of the fuel (as dispensed from the service station fuel pump or bulk storage), on-vehicle
fuel storage, and the on-vehicle fuel filtering of the diesel fuel prior to the fuel injection process.
-
Refer to the Owners Manual for fuel and fuel system information.
Proper Fuel And Fuel Quality:
-
Use good quality diesel fuel from a reputable supplier. It is recommended that purchase of diesel fuel should be made from a service station that is
known to dispense a high volume of highway diesel fuel.
-
** Ultra Low Sulfur Highway Diesel Fuel (15 ppm of sulfur or less and meeting ASTM D975 - grade 5-15) is required for use in Dodge Ram Trucks
equipped with a 6.7L diesel engine. **
-
** The 2007 Ram Truck Cab and Chassis (DC) vehicle is equipped with a 6.7L diesel engine. This vehicle is to use Ultra Low Sulfur Highway
Diesel Fuel. Due to limited availability of Ultra Low Sulfur Highway Diesel Fuel, during the initial production of this vehicle, Low Sulfur Highway
Diesel Fuel (500 ppm of sulfur or less) may be used ONLY until Ultra Low Sulfur Highway Diesel fuel becomes readily available and fuel pumps
that dispense Ultra Low Sulfur Highway Diesel Fuel are required to be labelled as such. This is expected to occur around October 15, 2006. **
-
** Ultra Low Sulfur Highway Diesel Fuel (preferred) or Low Sulfur Highway Diesel Fuel (500 ppm of sulfur or less) are required for use in Dodge
Ram Trucks equipped with a 5.9L diesel engine. **
-
A maximum blend of 5% biodiesel (B5) is acceptable as long as the biodiesel mixture meets ASTM specification D-975, D-975 - grade 5-15, and
ASTM D6751. A biodiesel fuel blend that is higher than 5% is not acceptable without additional fuel processing because these higher percentage
biodiesel blends contain excess amounts of moisture which exceed the water stripping capability of the on-engine final fuel filter. Should a higher
percentage biodiesel fuels be used an auxiliary water stripping filter will be required.
-
A maximum blend of 20% biodiesel (B20) can be used by government, military, and commercial fleets who equip their vehicle(s) with an optional
water separator, and adhere to the guidelines in the Department of Defense specification A-A-59693 (in addition to:
ASTM specification D-975, D-975 - grade 5-15 and ASTM D6751)
-
Off-highway diesel fuel (i.e. farm or marine use diesel fuel) that does not meet Ultra Low Sulfur Highway or Low Sulfur Highway fuel specifications
(as listed above) is NOT acceptable. Unknown sulfur and water content and unknown cetane number may adversely affect the performance of the
