FUEL RECOMMENDATIONS
CAUTION:
Engine shipped from Briggs & Stratton without fuel. Before starting
engine, fill with gasoline/oil mixture as specified in this manual.
To prevent engine damage, DO NOT use automotive oil, such as SAE
30 or 10W30, or fuel mixed at the wrong gasoline to oil ratio. Engine
damage will occur, and will not be covered under warranty.
This engine uses a 50:1 gasoline‐to‐oil mixture. Use clean, fresh,
unleaded gasoline with a minimum of 87 octane to mix with a high‐quality
two‐cycle oil meeting NMMA‐TCW3 or ISO GD specifications.

2 US Gallons (7.6 liters)
IMPORTANT:
- DO NOT mix gasoline and oil in the fuel tank.
- Oil at room temperature mixes easier and more thoroughly than
cold oil.
- Oil below 32° F (0° C) requires additional mixing.
1. Pour a half US gallon (1.9 liters) of fresh, unleaded gasoline into an
approved fuel container.
2. Add 2‐cycle oil to the gasoline according to the chart.
3. Install the cap on the fuel container.
