50 to 1 or 2.56 Ounces of oil per gallon of gas
Echo-branded oil is a 50:1 ratio and is available in bottles pre-measured to mix with certain quantities of gas.
40:1 is the original requirement but the Echo universal 50:1 oil can run it as well and will not the void any warranty.

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.
50:1 with Echo oil use 100ml of echo oil to 5 liters gas
The Gas/Oil ratio is 50:1
