All 2-cycle chain saws use a proper mix of gas and oil – ECHO recommends a 50:1 mix which is equal to 2.6 fluid ounce of oil for each (1) gallon of gas.
The fuel and oil mixture should always be 2% (50:1).
The general ratio for most two-stroke chain saw combustion engines is 50:1, though some manufacturers recommend 40:1. The larger number represents the amount of gasoline, while the smaller is the amount of oil needed.
Your Echo chainsaw is a two-stroke engine that takes a mixture of unleaded gasoline and two-stroke motor oil at a ration of 50 to 1.
If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
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.
The safest bet for any concrete mix is four-two-one: four parts crushed rock; two parts sand; and one part cement.
If you have a 1:3 dilution, i.e., a 1:3 dilution ratio, this means that you add 1 unit volume of solute (e.g., concentrate) to 3 unit volumes of the solvent (e.g., water), which will give a total of 4 units of volume.
The components typically need to be combined in the ratio 1:2:3:0.5 to produce concrete with the highest strength. In that ratio, there is 1 component of cement, two parts sand, three parts gravel, and 0.5 part water.
Echo chainsaws have two-stroke, air-cooled engines that require a mix of unleaded gasoline and two-stroke motor oil with a ratio of 50:1.

What oil ratio to petrol do I use?
ANSWER : 40:1 is the recommended ratio for this type of engine.

If you cannot measure accurately you should tend towards more oil rather than less. That will protect your engine and the only downside will be a slightly smokier exhaust and possible oiling of the plug over time.
