NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH THE 5.9L DIESEL ENGINE.
DISCUSSION:
For 1994, EPA has mandated the use of low sulfur diesel fuels to reduce the particulate emissions from diesel engines.
Sulfur in the fuel adds to the lubrication characteristics of diesel fuel. The new low sulfur fuels are designed to meet these fuel system lubrication
requirements without the need for additives. The use of diesel fuel additives to increase the lubricity of the low sulfur fuel is not required or
recommended.
The 5.9L diesel engine fuel system is compatible and has been designed to operate with low sulfur diesel fuels. Though the addition of a diesel fuel
additive to improve the fuel system lubricity will not damage the 5.9L diesel engine, the use of a fuel system lubrication additive will add unnecessary
expense to the operation of the vehicle and may increase particulate emissions.
The vehicle owner should consider purchasing diesel fuel from a high volume diesel fuel retailer, such as a large truck stop. Doing so will increase the
chances of purchasing diesel fuel which is high in quality and is fresh.
