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.
* 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.
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, remove oil cap/dipstick
and wipe dipstick with clean cloth. Replace
dipstick. Remove and check oil level.
NOTICE DO NOT screw in dipstick when checking oil
level.
3. Verify oil is at full mark (D) on dipstick. Replace
and tighten oil cap/dipstick.
Adding Engine Oil
1. Make sure generator is on a level surface.
2. Check oil level as described in Checking Oil Level.
3. If needed, slowly pour oil into oil fill opening to the
full mark on dipstick. DO NOT overfill.
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.
4. Replace and tighten oil cap/dipstick.
