, thread the cap back onto the tube.
5. Remove the dipstick and read the oil level. The oil
level should be between the “FULL” and “ADD” marks
(D). If not, add oil according to the “Recommended
Engine Oil” chart (see Figure 28).

*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.
