Servicing the Engine Oil

Checking the Engine Oil Level
Service Interval: Before each use or daily—Check the engine
oil level.
The engine is shipped with oil in the crankcase; however, the
oil level must be checked before and after the engine is first
started.
The crankcase capacity is 8.04 L (8.5 quarts) with the filter.
Use high-quality engine oil that meets the following
specifications:
•
API Classification Level Required: CH-4, CI-4 or higher.
•
Preferred oil: SAE 15W-40 (above 0°F)
•
Alternate oil: SAE 10W-30 (below 23°F)
Toro Premium Engine Oil is available from your distributor
in either 15W-40 or 10W-30 viscosity. See the parts catalog
for part numbers. Also, refer to the Engine Operator's Manual,
included with the machine, for further recommendations.
Note: The best time to check the engine oil is when the
engine is cool before it has been started for the day. If it has
already been run, allow the oil to drain back down to the
sump for at least 10 minutes before checking. If the oil level is
at or below the 'add' mark on the dipstick, add oil to bring the
oil level to the 'full' mark. Do not overfill. If the oil level is
between the 'full' and 'add' marks, no oil addition is required.
1. Park the machine on a level surface.
2. Remove the dipstick
the dipstick into the tube, and pull it out again. The oil
level should be up to the Full mark.
