The Echo SRM-225 trimmer typically operates on a fuel mixture of 50:1, meaning 50 parts gasoline to 1 part two-cycle engine oil. For example, this would translate to using 2.6 ounces of oil for every gallon of gasoline. It's essential to use the correct oil-to-gas ratio to ensure optimal performance and longevity of the engine. Always consult the manufacturer's manual for the most accurate specifications.
Echo-branded oil is a 50:1 ratio and is available in bottles pre-measured to mix with certain quantities of gas.
