Vanguard Oil Recommendations


For information regarding the oil capacity for your engine, please visit our Oil Capacity FAQ.

Oil Recommendation

  • SAE 30 40°F and higher (5°C and higher) is good for all purpose use above 40°F, use below 40°F will cause hard starting.

  • 10W-30 0 to 100 °F (-18 to 38 °C) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80°F(27°C) or higher.

  • Synthetic 5W-30 -20 to 120 °F (-30 to 40 °C) provides the best protection at all temperatures as well as improved starting with less oil consumption.

  • 5W-30 40 °F and below (5 °C and below) is recommended for winter use, and works best in cold conditions.

Type of oil to use

  • Use a high quality detergent oil classified "For Service SF, SG, SH, SJ" or higher.

  • Do not use special additives.

  • Choose a viscosity according to the table above.

*NOTE:  Briggs & Stratton engines are not designed to run on E85 fuel. E85 is a blend of 85% ethanol (alcohol) and 15% gasoline, which is not compatible with most engines intended to run on regular gasoline. While alcohol is an excellent octane booster, it delivers less power, having an energy value of only about 77,000 Btu per gallon versus 114,000 Btu for regular gasoline. E85 also demands a different fuel-to-air ratio to burn efficiently, requiring specially calibrated carburetors. Further, specially designed fuel system components are required to withstand the high alcohol concentration found in E85.
