according to your expected temperature. (See Fig. 10)
Fig. 10
NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, they will result in increased
oil consumption when used above 32°F (0°C). Check your
engine oil level more frequently to avoid possible engine
damage from running low on oil.
Change the oil after every 25 hours of operation or at
least once a year if the tiller is not used for 25 hours in
one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.
