Question

Mr. B’s small engines require a mix of 4 ounces of oil for every 6 gallons of gasoline. How much oil is used per gallon of gasoline?
(your answer must be in fraction form and simplest form)

Answer 1

Answer:

Outboard engines, leaf blowers, weed trimmers and other equipment with small engines often have a 2-cycle, also known as 2-stroke, engine. If the engine has a single fill port for both engine oil and gas, it is a 2-cycle engine that requires a specific mix of oil and gas to function properly.

What Is the Right Ratio

The mixture of gas and oil is written as a ratio that represents the parts of gasoline and the parts of oil. The ratio needed in the 2-cycle oil mix for your engine can be found in the equipment operator’s manual or on the engine label. If you cannot locate either, but know the equipment’s age, refer to the following: most handheld equipment manufactured before 2003 requires a 32:1 ratio; most handheld equipment made after 2002 uses a 40:1 or 50:1 ratio. Most outboard motors require a 50:1 ratio.

How to Create the Oil Mix

Pour the correct amount of 2-stroke oil into a clean gas can.

Add the correct amount of gasoline.

Stir or shake the container to mix the oil and gas.

Use the mixture within 30 days or add fuel stabilizer to extend the shelf life.

2-Stroke Oil Mix Calculator

For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas.

For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.

For a 32:1 mixture, use 4 fluid ounces of oil per gallon of gas.

Important Warnings

Do not use automobile motor oil, which contains noncombustible additives that will damage your engine; only use 2-cycle engine oil.

Do not use gasoline with more than 10 percent ethanol, which attracts moisture, causes gasoline to break down and can lead to engine damage.

Do not guess at the right ratio or approximate the amounts of either gasoline or oil; your engine requires a specific mixture of fuel and lubrication to run properly.

Do not combine the gas and oil in the engine directly; always mix in a separate, clean container.

If your engine has been idle for more than a month, such as when coming out of winter storage, check the fuel to make sure the mixture hasn’t degraded
