SUBJECT:
5.9L And 6.7L Cummins Diesel Engines - Correct Low And Ultra-Low Sulfur Highway Diesel Fuel Use

(DHID1IDC)
Ram Truck
NOTE:
This bulletin applies to vehicles equipped with a 5.9L or a 6.7L turbo-diesel engine (sales code ETH and ETJ respectively).
DISCUSSION:
2007 M.Y. Dodge Ram trucks equipped with a 6.7L Cummins Turbo-Diesel engine are required by Federal law to be fueled with Ultra-Low Sulfur
Diesel fuel.
2007 M.Y. Dodge Ram trucks equipped with a 5.9L Cummins Turbo-Diesel engine are allowed by Federal law to be fueled with Low Sulfur Diesel fuel,
and are encouraged to fuel with Ultra-Low Sulfur Diesel fuel.
As of June 1, 2006, a new United States Environmental Protection Agency (EPA) regulation required at least 80% of the United States diesel fuel
production to be Ultra-Low Sulfur Highway Diesel fuel. Ultra-Low Sulfur Highway Diesel fuel has a sulfur content of 15 part per million (ppm).
The new Ultra-Low Sulfur Highway Diesel fuel enables vehicles equipped with the advanced emissions control devices to achieve more stringent U.S.
EPA vehicle emissions standards.
By October 15, 2006, retail fuel stations that carry and dispense Ultra-Low Sulfur Highway Diesel fuel must label their fuel pumps with a Ultra-Low
Sulfur Highway Diesel Fuel label (Fig. 1), and must meet the 15 ppm sulfur maximum requirement.
