Changing the Engine Oil
Service Interval:
After the first 5 hours—Change the engine
oil.
Every 50 hours—Change the engine oil. Change the
engine oil every 25 operating hours when operating
the engine under a heavy load.
If possible, run the engine just before changing the oil because
warm oil flows better and carries more contaminants.
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 51 below to select the best oil viscosity for the
outdoor temperature range expected:
