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.
Check Tire Pressure
Tires should be checked periodically to provide the optimum
traction and to guarantee the best cut (see Figure 4).
NOTE:
These pressures may differ slightly from the
“Maximum Inflation” stamped on the side walls of the tires.
** Above 80° F (27° C) the use of 10W30
may cause
increased oil consumption. Check oil level more
frequently.
* Below 40° F (4° C) the use of SAE 30
will result
in hard starting.
