Changing the Engine Oil

Service Interval: After the first 5 hours—Change the engine
oil.
Every 25 hours/Yearly (whichever comes
first)—Change the engine oil.
If possible, run the engine just before changing the oil because

Use automotive detergent oil with an API service classification
of SF, SG, SH, SJ, SL, or higher. Refer to your engine owner's
manual.
Use Figure 42 below to select the best oil viscosity for the
outdoor temperature range expected:
