Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certi ed oils for best performance. Other high-quality de-
tergent oils are acceptable if classi ed 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 10W-30 may cause increased oil
consumption. Check oil level more frequently.
