Engine Oil - Briggs & Stratton 040375-02 Operator's Manual

Engine Oil

The engine is filled with synthetic oil (API SJ/CF 5W-30).
This allows for system operation in the widest range of
temperature and climate conditions.
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SJ or
higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity
for the engine. Use the chart to select the best viscosity for
the outdoor temperature range expected.
NOTICE Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with "SJ/
CF ENERGY CONSERVING" or higher, is an
acceptable oil at all temperatures. Use of synthetic
oil does not alter required oil change intervals.
Changing Engine Oil and Oil Filter
Open roof and remove front panel to access the oil filter
and to add engine oil.
Checking/Adding Engine Oil
1. Open roof to access dipstick and oil fill area.
2. Clean the oil fill area of any debris.
3. Remove the dipstick and wipe with a clean cloth.
4. Fully insert dipstick into oil fill.
* Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
** Above 80°F (27°C) the use of 10W30 may cause
increased oil consumption. Check oil level more
frequently.
5. Remove dipstick and check oil level. Verify oil is at
Full mark on dipstick.
6. If needed, slowly pour recommended oil into oil fill
opening. DO NOT overfill. After adding oil, wait one
minute and recheck oil level.
NOTICE Overfilling with oil could cause the engine to not start,
or hard starting.
• DO NOT overfill.
• If over the FULL mark on dipstick, drain oil to reduce oil level
to FULL mark on dipstick.
7. Replace oil dipstick.
8. Close roof and secure.
