Hope this helps, Antonio.
Most 2-stroke engines will run efficiently on 1/2 ounce of oil to a gallon of gas. Make sure it is 2 stroke oil, not regular engine oil.
Usually the average is about 4 ounces of oil per gallon of gas
If the owner uses ordinary two-stroke oil, the mix is 32 to 1 (or 4 ounces of oil per gallon of gasoline). The manual for this unit can be a little confusing regarding fuel mix because it gives a mix for Homelite's specific two-stroke oil, but it does indicate the 4 ounce per gallon mix for regular two-stroke oil.
Three ounces of Two-Stroke oil per gallon of gas
It depends on the brand of trimmer you bought. Stihl, Echo, Husqvarna use 50:1, or 1 gallon of GAS to 2.6oz of 2-stroke oil Weed Eater, Poulan, and Poulan Pro use 40:1, or 1 gallon of GAS to 3.2oz of 2-stroke oil Ryobi's use 32:1, or 1 gallon of GAS to 4oz of 2-stroke oil
6.4 ounces for each gallon of gas.
1 gallon of oil to 250 gallons of gas is 1.953125 ounces per gallon; you would need 39.0625 ounces of oil for 20 gallons of gas.
1 gallon of GAS to 3.2oz 2-stroke oil or 2%
I suppose you are referring to oil/gas mixture for a two-stroke engine. Pour the recommended amount per gallon of two-stroke oil into an empty one-gallon gas can and then fill with gasoline. The force of the gas going in will help the oil to mix in properly. For added confidence, shake the container a little before adding the fuel to the gas tank.
1 US gallon = 128 fluid ounces. in a 100 to 1 ratio you would need to add 1.28 fluid ounces.
50 to 1 ,or 2.6 OZ. per gallon of gas of 50:1 2 stroke oil
