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 4° C (40° F) the use of SAE 30 will result in hard
starting.
** Above 27° C (80° F) the use of 10W30 may cause
increased oil consumption. Check oil level more frequently.
Checking Oil Level
Figure

Oil level should be checked prior to each use or
at least every 8 hours of operation. Keep oil level
maintained.
