Checking the Engine Oil
Service Interval: Before each use or daily
The engine is shipped with 3.7 L (3.9 US qt) (with
filter) of oil in the crankcase; however, you must check
the oil level before and after starting the engine the
first time.
Use high-quality engine oil that meets the following
specifications:
•
API Classification Level Required: CH–4, CI–4 or
higher.
•
Preferred oil: SAE 10W–30
•
Alternate oil: SAE 15W–40
Toro Premium Engine oil is available from your
distributor in the 10W–30 viscosity. See the Parts
Catalog for part numbers.
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 F
mark. Do not overfill.
Important:
Keep the engine oil level between the
upper and lower limits on the oil gauge; the engine
may fail if you run it with too much or too little oil.
1. Position the machine on a level surface.
2. Remove the dipstick and wipe it with a clean rag
(Figure 32).
Important:
Remove the dipstick while filling
the engine with oil. When adding engine
oil or filling oil, there must be clearance
between the oil fill device and the oil fill
hole in the valve cover as shown in
31. This clearance is necessary to permit
venting when filling, which prevents the oil
from overrunning into the breather.
