Servicing the Engine Oil

Oil Specification
Use high-quality, low-ash engine oil that meets or
exceeds the following specifications:
•
API service category CJ-4 or higher
g194209
•
ACEA service category E6
•
JASO service category DH-2
Important:
Using engine oil other than API CJ-4
or higher, ACEA E6, or JASO DH-2 may cause the
diesel particulate filter to plug or cause engine
damage.
Use the following engine oil viscosity grade:
•
Preferred oil: SAE 15W-40 (above 0°F)
•
Alternate oil: SAE 10W-30 or 5W-30 (all
temperatures)
Toro Premium Engine Oil is available from your
Authorized Toro Distributor in either 15W-40 or
10W-30 viscosity grades. See the parts catalog for
part numbers.
Checking the Engine-Oil Level
Service Interval: Before each use or daily
The engine is shipped with oil in the crankcase;
however, the oil level must be checked before and
after the engine is first started.
Important:
Check the engine oil daily. If the
engine-oil level is above the Full mark on the
dipstick, the engine oil may be diluted with fuel;
If the engine oil level is above the Full mark,
change the engine oil.
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 the engine with oil.

Important:
Keep the engine oil level between the
upper and lower limits on the dipstick; the engine
may fail if you run it with too much or too little oil.
1. Park the machine on a level surface.
2. Check the engine-oil level
