What Does the 40:1 Fuel to Oil Ratio Mean for 2-Stroke Engines?

Learn why the 40:1 fuel to oil ratio is essential for 2-stroke engine lubrication and how to mix fuel properly for optimal engine performance.

37 views

The 40:1 ratio for 2-stroke engines refers to the mixing of fuel and oil, indicating 40 parts of fuel to 1 part of oil. This mixture ensures proper lubrication of the engine's moving parts, preventing damage from friction and overheating. To achieve this mixture, for every gallon of gasoline, add 3.2 ounces of two-stroke engine oil. It's crucial for maintaining the longevity and efficiency of 2-stroke engines.
