To optimize engine performance, use Warranty Certified Briggs & Stratton® Small Engine Oil. Synthetic 5W-30 provides the best protection at all temperatures as well as improved starting with less oil consumption. See chart on right for more oil information.
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°F to 100°F (-18°C 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. Check oil level frequently at higher temperatures.
Synthetic 5W-30: -20°F to 120°F (-30°C 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.
