What Oil To Mix With Gas For Weed Eater?

You can use premium two-cycle motor oil for air-cooled engines to mix with gas for weed eaters in the same ratio. Weed eater units run on 87 octane regular unleaded gasoline or blended with 10% alcohol. However, always read the manual to know the right weed eater fuel, like fresh gasoline, while avoiding E85 or diesel.

Alternatively, you can temporarily use engine and motor oil, but they don’t lubricate properly when mixed with gasoline. Hence, parts of the weed eater end up grinding on each other when the weed eater is in constant use.

However, engine oil pollutes the air more than 2-stroke oil, which burns clean. Unlike motor engines, 2-cycle products need oil added to gas for lubrication and smooth running. Hence, avoid using straight gas, as it will ruin the engine almost immediately.

The Weed Eater products have a two-cycle engine with a gas to oil ratio of 40:1. This ratio equals 3.2 ounces (oz) of oil to a gallon of regular gas. Ensure that the gas you use is 87 octane, a 10% alcohol concentration and not more.

Further, the oil must be recommended for two-cycle engines, and avoid automobile motor oil because it can foul the engine. Motor oil consists of noncombustible additives.

Exercise caution when mixing gas and oil, and if you mistakenly use an octane rating below 91, service the weed eater immediately. You’ll know all is not well with your weed trimmer engine if you hear heavy knocking.
