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 viscos-
ity for the engine. Use the chart to select the best vis-
cosity 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 10W-30 may cause
increased oil consumption. Check oil level more
frequently.
