To achieve a 32:1 ratio with 1 gallon of gasoline, you would need to mix 4 fluid ounces of 2-stroke oil with the gasoline. This results in a ratio of 32 parts gasoline to 1 part oil.
It depends on the mixing ratio of gasoline / oil for the specific piece of equipment you will use the gas / oil mix. Most lawn equipment such as weed eaters and leaf blowers require a 32:1 mixture. Since 1 gallon of gasoline is 128 ounces, it is necessary to mix 128 ounces (or 1 US gallon) of gasoline to 4 ounces of 2 cycle oil to equal 32:1 ratio.
2.6 ounces of oil to one gallon of unleaded gasoline.
There is 128 oz in a liquid gallon so to achieve a 40 to 1 ratio you would add approximately 3.2 oz of 2 cycle oil to one gallon of gasoline.
There are 128 ounces in a gallon. So, the ratio of ounces to gallons is 1:128.
50:1
The standard oil-to-gasoline ratio for a two-stroke engine is typically 1:50, which equates to 2.6 ounces of oil per gallon of gasoline. However, it's important to check the manufacturer's recommendations for the specific engine you are using to ensure proper lubrication.
It says on the back of any jug you buy in stores. I don't have one hand to tell you. It doesn't have to be exact but close. I normally just pour it out myself guessing. But that's not the smartest thing to do.
The ratio is 40:1 which come to 3.2oz of oil per gallon of gasoline.
1 gallon = 128 fluid ounces 1/50 of a gallon = 2.56 fluid ounces
.5 gallon = 64 ounces64/40 = 1.6 ounces
Divide the number of ounces in a gallon of gasoline by the number of ounces of oil (both fluid measurements). 128/2.6=49 (about) Essentially this is a 50:1 mix. Conversely if you want a 50:1 mix divide 128 by 50. Answer is 2.56. for 2 gallons 256/50=5.1 ounces. 2-1/2 gallons of gas will take 6.4 ounces of oil.
