Oil Recommendations
Using the proper type and weight of oil in the
crankcase is extremely important. So is checking oil
daily and changing oil regularly. Failure to use the
correct oil, or using dirty oil, causes premature engine
wear and failure.
Oil Type
Use high-quality detergent oil of API (American
Petroleum Institute) service class SJ or higher. Select
the viscosity based on the air temperature at the time
of operation as shown in the following table.

TEMPERATURE RANGE EXPECTED BEFORE NEXT OIL CHANGE
* Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable,
up to 4°C (40°F)
** Synthetic oils will provide better starting in extreme cold below
-23°C (-10°F)

higher oil or extending oil change intervals
longer than recommended can cause engine
damage.

at the recommended intervals. However to
allow piston rings to properly seat, a new or
rebuilt engine should be operated for at least
50 hours using standard petroleum based oil
before switching to synthetic oil.

Check Oil Level

The importance of checking and maintaining
the proper oil level in the crankcase cannot be
overemphasized. Check oil BEFORE EACH USE as
follows:
1. Make sure the engine is stopped, level, and is
cool so the oil has had time to drain into the
sump.
2. To keep dirt, grass clippings, etc., out of the
dipstick before removing it.
Figure 6-3. Reinsert the dipstick into the tube and
fully seat the dipstick in the tube. See Figure 6-4.
