IMPORTANT:
• For machines operated in the U.S.: The engine in this product is certified to operate on low sulfur
diesel fuel (LSD) with a sulfur content of 500 ppm (0.05%) or less. Use LSD or ultra low sulfur fuel
(ULSD) only. Using fuels with higher sulfur content will affect exhaust emissions. Such action is a
violation of the US Clean Air Act and US EPA regulations and will result in fines.
• For machines operated outside the U.S.: Fuel sulfur content should be less than 5000 ppm (0.05%).
Worldwide fuel sulfur regulations vary widely. Fuel used should always comply with local
regulations. If fuel sulfur content exceeds 5000 ppm, use a lube oil meeting API CF (or equivalent)
with a TBN value of 10 or greater. Do not use lube oils meeting API CJ-4 (or other low SAPS
equivalent) under any conditions.
