Servicing the Engine Oil and
Filter
Crankcase capacity: 15.0 L (15.9 US qt) with the filter.
Use only high-quality SAE 15W-40 heavy-duty engine oil with
an API classification of CH-4 or higher.
While SAE 15W-40 oil with an API classification of CH-4 or
higher is recommended for most climates, refer to
for oil viscosity recommendations for extreme climates.

Note: Limited use of low-viscosity oils such as SAE 10W-30
with an API classification of CH-4 or higher can be used for
easier starting and providing sufficient oil flow at ambient
temperatures below -5°C (23°F). However, continuous use of
low viscosity oil can decrease engine life because of wear.
Toro Premium Engine Oil is available from an Authorized
Toro Service Dealer in either 15W-40 or 10W-30 viscosity
with API classification CH-4 or higher. See the Parts Catalog
for part numbers. Also, refer to the Engine Operator's Manual,
included with the machine, for further recommendations.

Draining the Engine Oil
1. Run the engine until the water temperature reaches
60°C (140°F).
Note: Warm oil drains better and carries more
contaminants.
2. Stop the engine.
3. Remove the right side panel; refer to
Side Panels (page 45).
4. Place a drain pan that has a minimum capacity of 20 L
(21 US qt) under the engine-oil drain fitting
