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.
Product Details. The ECHO Power Blend 16 oz. 2-stroke Engine Oil with Fuel Stabilizer blends with 89-octane gasoline at a 50:1 gas-to-oil ratio for clean-burning, steady performance.
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.
The fuel and oil mixture should always be 2% (50:1).
Tips for properly mixing fuel for a chainsaw:

Always mix the petrol and oil in a clean container intended for fuel. Always start by filling with half of the petrol to be used, then add all of the oil, mix (agitate) the fuel mixture and add the remaining petrol. Do not mix more than one month`s supply of fuel at a time.

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.
The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
Mid-grade unleaded gasoline with a minimum octane rating of 89 is recommended for your mixture. Fuel with a lower octane rating may increase engine temperatures, increasing the risk of piston seizure and damage to the engine.
Both use high-quality materials. Echo chainsaws are designed to be lighter in weight than Stihl. This is done by incorporating aluminum into the build of their saws making it a more comfortable chainsaw to operate. In review of the engines for Echo and Stihl, there really is no comparison between them.
It`s clear that the Stihl is the more powerful string trimmer when compared to the ECHO. At the end of the day, both are more than enough power for residential use. But if you have any brush in your backyard that you want to slice down, the Stihl FS 56 RC is going to get it done faster.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas.
