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 8.5 qt (8.04 l) 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 (Figure 59)., wipe it clean, install
the dipstick into the tube, and pull it out again. The
oil level should be up to the Full mark.
