• Toro Weed Wacker Fuel Oil Ratio Chart

Dec 19, 2018 All Weed Eater brand two-cycle gas trimmers use a 40:1 ratio of gas to oil. That’s equal to 3.2 ounces of oil to 1 gallon of regular gas. The gas should be 87 octane with no more than 10 percent. To mix two-cycle fuel, start by putting the correct amount of oil in the gas can. Then slowly add the correct amount of gasoline. Do not try to mix the gas and oil directly in the gas tank of the equipment. IMPORTANT: Do not use any fuel that is over 30 days old. Do not mix more fuel than you are likely to use in a month.
