ENGINE OIL RECOMMENDATIONS

We recommend the use of high-quality detergent oils 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.
