Engine Oil Temperature Chart
IMPORTANT: Fuel sulfur content should be less than 5000 ppm (0.5%). Worldwide, fuel sulfur
regulations vary widely. Fuel used should always comply with local regulations. If using fuel with sulfur
content above 5000 ppm (0.05%, low sulfur diesel in the U.S.), reduce oil change interval by half.
NOTICE: Do not use water or high-silicate automotive-type coolant. This will lead to engine damage or
premature engine failure.
NOTICE: Do not mix heavy-duty diesel engine coolant and automotive-type coolant. This will lead
coolant breakdown and engine damage.
