The amount of 2-cycle oil to mix per gallon of gasoline depends on the recommended fuel-to-oil ratio for your specific 2-cycle engine. Common ratios are:

• 50:1 ratio (most newer 2-cycle engines): Use 2.6 ounces of 2-cycle oil per 1 gallon of gasoline.
• 40:1 ratio (some older engines): Use 3.2 ounces of 2-cycle oil per 1 gallon of gasoline.
• 32:1 ratio (older handheld equipment, pre-2003): Use 4 ounces of 2-cycle oil per 1 gallon of gasoline

To summarize:

Gas to Oil Ratio| Oil per 1 Gallon of Gasoline
---|---
50:1| 2.6 ounces
40:1| 3.2 ounces
32:1| 4.0 ounces

Check your equipment’s fuel cap, manual, or manufacturer’s website for the exact ratio recommended for your engine. Mixing the correct ratio is crucial to avoid engine damage
