Engine Maintenance
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 or
higher . Do not use special additives . See Common Service
Parts.
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 .

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