If your chainsaw is using too much bar oil, you may need to clean the bar and chain and rid it of built-up dirt and debris. You can do this by spraying a degreaser onto the bar and chain and letting it sit for a few minutes before wiping them clean with a rag.
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. This mixture equates to one gallon of gasoline to 2.6 ounces of the two-stroke motor oil.
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.
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.
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.
In all but very exceptional cases there is nothing wrong with the chainsaw and what appears to be an oil leak is simply oil that has sprayed from the chain as it rotates at high speed, draining from the saw body and guide bar.
With a narrow flat-tipped screwdriver, adjust the oil flow. To increase the oil flow, turn the automatic oiler adjustment screw counterclockwise.

Dripping oil from the exhaust is an indication of several things that could be going on. Most commonly either the fuel is stale or mixed incorrectly or incorrect oil. Next is maintenance of the unit, air filter restricted, spark arrestor, carburetor adjustment.

How to take out the piston in my chain saw – Echo CS400 18" Chain Saw
ANSWER : The cylinder must be removed from the crankcase (be sure to clean the exterior of the engine and all parts with compressed air first). That involves removing the carburetor, muffler, cylinder head, and possibly the entire outer case parts. If the piston/ring(s) requires replacement due to scuffing, the cylinder will likely need to be replaced also. Many modern engines use a chrome plated lining for the cylinder interior and any piston damage will affect the cylinder plating also. Use great care when installing the new piston in the cylinder as the ring(s) are quite fragile. Also look for direction marks on the piston as some engines use an offset pin. Be sure to lubricate everything as you go with saw oil to prevent start-up damage. Hope this helps!
