The oil change interval will be affected by the following items:
Engine application
Size of the oil sump
Fuel type
Oil type
Ambient air conditions
Air/fuel ratioThe S O S oil analysis program analyzes used oil in order to determine if the oil change interval is suitable for your specific engine. In the absence of S O S oil analysis, change the engine oil and engine oil filters according to the interval that is listed in Table 1.

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Drain the Oil
Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase when the oil is warm. This method allows proper draining of the waste particles that are suspended in the oil.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine.
