The maximum amount of oil that meets this standard is 40:1, or 3.2 ounces of oil per gallon of gasoline. 50:1, or 50 parts gasoline to 1 part 2-cycle oil is 2.6 ounces of oil per gallon of gasoline. Superior oil is synthetic, or blended synthetic oil. There is very little difference in 50:1 and 40:1 fuel mix.

Mixing Ratio (Gas:Oil) Volume of Gasoline Volume of 2-Cycle Oil

———————- —————— ———————

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

Moreover, How do you calculate a 50 to 1 ratio?

You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you’re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture. I would recommend using fresh gasoline that has an octane rating of 89.

Secondly, How do you calculate a mix ratio?

HOW TO CALCULATE PERCENTAGE IF MIX RATIO IS KNOWN. Divide 1 by the total number of parts (water + solution). For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).

Simply so, What does 40 to 1 mixture mean?

No, 40:1 oil to fuel ration means mixing 40 equal parts of fuel to 1 equal part of oil. This means to add 3.2 ounces of 2 cycle oil to one gallon of gas in order to make a ratio of 40:1 fuel mixture.

How much oil do I need for a 50 to 1 ratio?

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.
