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

The Echo PB-413T leaf blower requires a fuel mixture of 50:1, which means 50 parts gasoline to 1 part 2-stroke oil. This typically translates to using 2.6 ounces of 2-stroke oil for each gallon of gasoline. Always use high-quality oil designed for air-cooled 2-stroke engines to ensure optimal performance.
