Safety and Environmental Considerations
All Freightliner diesel engines comply with the requirements of the Federal (U.S.) Clean Air Act. Once an engine is placed in service, the responsibility for meeting local jurisdictional regulations is with the owner/operator.
Important: Depending upon local jurisdictional emissions guidelines, vehicles and/or engines that are domiciled outside of the U.S. and Canada may not be compliant with current emissions regulations.
Notice: It is extremely important that the following guidelines be followed for vehicles with EPA07 or newer engines, or damage may occur to the aftertreatment device, and the warranty may be compromised.
-
Use ultralow-sulfur diesel with 15 ppm sulfur content or less.
-
Do not use fuel blended with used engine lube oil or kerosene.
-
Use only approved engine lube oil. For lists of engine oils approved for Detroit Diesel engines, refer to the Engine Operator Manual, accessible on Lubricants, Fuels & Coolants on the DTNA Portal. For third party engines, please refer to the engine manual.
A Top Tier™ compliant fuel is recommended. Look for the symbol that denotes a Top Tier compliant fuel; see Fig..

Adequate maintenance of the engine and the diesel particulate filter (DPF) are the responsibility of the owner/operator, and are essential to keep the emission levels low. Good operating practices, regular maintenance, and correct adjustments are factors that will help keep emissions within the regulations.
