50:1 regardless what the prior manuals say, thats what my manual from echo says as of 1/4/2013
what is the gas mixture for an echo leaf blower P B260 L
Valvoline 2cycle oil ^^^^^^^^^^^^^^^^This does not answer the question... idiots.. smh. The answer is 50:1.
50:1, or 1 gallon of GAS to 2.6oz. of 2-stroke oil
Echo-branded oil is a 50:1 ratio and is available in bottles pre-measured to mix with certain quantities of gas.
50:1
Echo brand
The ECHO PB770H leaf blower uses a 50:1 fuel-to-oil mixture, which means you should mix 2.6 ounces of 2-stroke oil with one gallon of gasoline. It's important to use a high-quality, ethanol-free gasoline and ensure the oil is specifically formulated for air-cooled 2-stroke engines. Always refer to the owner's manual for any specific recommendations or guidelines.
Leaf blowers or leaf blowing VACs can be purchased from stores stocking outdoor and garden related hardware and appliances. Alternatively, such products might be purchased through online vendors such as Amazon.

I have a pb 2100 made in 2000 all my echo prouduct's call for 89 octane fuel and echo two stroke oil mixed 50-1 . I run the same mixture in my pb 2100 , pb 251, and pb 250 leaf blower and even my srm 225 weedeater. So this is the correct mix to use in anything that has a two cycle motor.

About 1/8 inch is close enough
