The Toro Company provides two gas-powered trimmers, frequently referred to as weed whackers, to assist homeowners maintain their lawn trimmed. Both lightweight models feature a complete crank, 25.4-cc two-cycle engine layout for balanced handling. The trimmers use a blend of two-cycle and gas engine lubricant, held in an 18-ounce gas tank.
Mix up it
The proper proportion of gas and oil is 50-to-1, which means for each 1 gallon of gas, you need to add 2.6 ounces of two-cycle engine oil. Toro recommends having a premium quality synthetic lubricant that is two-cycle. Don’t use lubricants made for outboard motors or automobiles. Mix the oil and gas in a resealable container and do not prepare more than you can use in a 30-day period. (Ref 1, p. 14)
