Servicing The Engine Oil - Toro 139-5637 Instructions Manual

Servicing the Engine Oil

Fill the crankcase with approximately 0.56 L (19 fl
oz) of the proper viscosity oil before starting. The
engine uses a high-quality oil that has the American
Petroleum Institute (API) service classification of SJ or
higher. Select the proper oil viscosity (weight) based
on the ambient temperature. Figure 9 illustrates the
temperature/viscosity recommendations.

Note:
Multi-grade oils (5W-20, 10W-30 and 10W-40)
increase oil consumption. Check the engine-oil level
more frequently when you use these oils.
Checking the Engine-Oil Level
Service Interval: Before each use or daily
The ideal time to check the engine-oil level is when the
engine is cool or before you have started the engine
for the day. If you have already ran the engine, allow
the oil to drain back down to the sump for at least 10
minutes before you check the engine-oil level.
