Mix a Gallon of Gas for a Two Stroke Engine

Most two stroke engines in dirt bikes, snowmobiles, dirt bikes and chain saws require a premixed combination of gasoline and two cycle oil. The gasoline powers the engine while the oil lubricates the cylinder walls and reduces friction which keeps the engine going. Therefore, a proper mix of the two components is crucial in the performance and longevity of the engine.

Steps

  1. Pump one gallon of gasoline into a gas can.
  2. Measure out the proper amount of two cycle oil in the Ratio Rite.
  3. Pour the required amount of oil into the gas can with the gasoline.
  4. Shake the container lightly until all of the oil is thoroughly mixed in with the gasoline.
  5. Pour the mixture into the machine`s gas tank.
  6. Alternate steps -
  7. Pour the required amount of oil into a gas can
  8. Pump one gallon of gasoline into the gas can with the oil
  9. - You're finished, pumping mixes gas and oil

Tips

  • 50:1(gasoline:oil) ratio requires 2.6 ounces of oil.
  • 40:1(gasoline:oil) ratio requires 3 ounces of oil.
  • 100:1(gasoline:oil) ratio requires 1.3 ounces of oil.
  • 32:1(gasoline:oil) ratio requires 4 ounces of oil.
  • Thoroughly mixed gasoline will have no light or dark areas and will have even shading throughout.
  • BEFORE USING THIS CHART - MAKE SURE YOU ARE USING THE RIGHT SIZE GALLON - US or IMPERIAL. To find out how much gas is really needed, you should simply use the equation G times 128 divided by M. G = gallons you have(i.e. i have 20 gallons and M = ratio number(i.e. 40:1 40 would be used).
  • 20:1(gasoline:oil) ratio requires 6 ounces of oil.
  • Be sure all of the caps and nozzles are secured on the gas can before shaking.
  • 70:1(gasoline:oil) ratio requires 1.8 ounces of oil.
  • Use a gas can that holds more than one gallon of gasoline because the added oil could cause an overflow in a one gallon can.

Warnings

  • US GALLONS ARE A DIFFERENT SIZE TO IMPERIAL ONES
  • Always work with gasoline in a well ventilated area.
  • Never work with gasoline near open flames.

Things You'll Need

  • One gallon of gasoline (REMEMBER US AND IMPERIAL GALLONS ARE OF DIFFERENT SIZES)
  • Six ounces (or less) of two cycle oil
  • Gas can
  • Ratio Rite (used to measure out the correct amount of oil)
