Figure 18. Recommended Engine Oil
Use oil classified API Service Class SF,
SG, SH, SJ or better with SAE Viscosity:
10080604020 320-20
3827164-7
0-18-30

30 Conventional**
Synthetic 5W-30, 10W-30

Conventional*
*CAUTION: Air cooled engines run hotter than automotive engines.
The use of non-synthetic multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40º F (4ºC) will result in higher than normal
oil consumption. When using a multi-viscosity oil, check oil level
more frequently.
**CAUTION: SAE 30 oil, if used below 40º F (4ºC), will result in hard
starting and possible engine bore damage due to inadequate
lubrication.
Oil Drain Valve Operation
Service Interval: As Required
1. Place a suitable container with a 4 quart capacity
under the oil drain valve (C, Figure 2).
2. Loosen or remove the dip stick (A).
3. Wipe oil drain valve (A, Figure 17) and cover (B) with
paper towel or rag.
NOTE: Sliding a hose with a 1/2” (12.5 mm) inside diam-
eter tube over the valve nipple may aid in guiding the
draining oil.
4. Rotate the drain valve counterclockwise and pull out
1/4” (6.35 mm) for engine oil to drain. Allow ample
time for complete drainage.
5. After all the oil has drained, close the oil drain valve
by pushing in and rotating clockwise to close.
6. Wipe the nipple (C) with paper towel or rag. Install
the cover (B) over nipple (C).
Change Engine Oil
Service Interval: 50 hours or once per season
Oil Capacity: Approximately 1-7/8 quarts (1.8 L) without
filter change.
NOTE: Change engine oil while the engine is warm. Run
the engine for a few minutes, then shut the engine off
and allow it to cool from hot to warm.
1. Clean the area around the dip stick (A, Figure 2) and
oil drain valve (C).
2. Drain engine oil. See “Oil Drain Valve Operation”
above.
3. Fill the crankcase with oil. See “Check Engine Oil
Level.”
Change Engine Oil & Filter
Service Interval: 100 hours or once per season
Oil Capacity: Approximately 2 quarts (1.9 L) with oil filter
change
NOTE: Change engine oil while the engine is warm. Run
the engine for a few minutes, then shut the engine off
and allow it to cool from hot to warm.
1. Clean the area around the dip stick (A, Figure 2) and
oil drain valve (C).
2. Drain engine oil. See “Oil Drain Valve Operation”
above.
3. Remove the oil filter (D). Discard the filter.
4. Using a drop of oil on your finger tip, wet the rubber
gasket on the bottom of the new filter.
5. Turn the filter clockwise until the rubber gasket meets
the filter base. Then turn 1/2 to 3/4 turn more.
6. Fill the crankcase with oil. See “Check Engine Oil
Level.”
7. Test run the engine to check for leaks. Stop the
engine for 1 minute, then recheck the oil level.
