Two-cycle (or 2-stroke) engines require a mixture of fuel and oil be added to the fuel tank. This mixture results in both engine combustion and lubrication. Operating a 2-Stroke engine on gasoline alone will result in engine failure.
Refer to the chart before fueling to make sure you're using the correct 2-cycle fuel and oil mixture:
Mixing Ratio (Gas:Oil)
|Volume of Gasoline|| |
Volume of 2-Cycle Oil
|32:1||1 US gal. (128 oz)||4 oz.|
|40:1||1 US gal. (128 oz)||3.2 oz.|
|50:1||1 US gal. (128 oz)||2.6 oz.|
|32:1||1 liter||31.25 ml|
|40:1||1 liter||25 ml|
|50:1||1 liter||20 ml|
Pour the 2-Cycle Oil to an empty gasoline can before adding one gallon of fresh gasoline into the can. No additional agitation is necessary. If the mixture may be stored for more than 30 days, include a fuel stabilizer to the gasoline before mixing to help increase its shelf life.
Label the gas can containing the 2-cycle oil mixture, to prevent accidentally using it in other equipment, such as your lawn mower.
