Oil
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF, SG,
SH, 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.
16
* 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.
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.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Clean area around oil fill and remove oil fill cap.
3. Verify oil is at the point of overflowing at oil fill
opening.
4. Replace and tighten oil fill cap.
Adding Engine Oil
