Owning a weed wacker means knowing how to use and maintain one properly. However, it is possible that your weed wacker may need oil, and you ought to know what to do when it does.

Maintenance Basics: Do Weed Wackers Need Oil?
It depends on what type of weed wacker you have. If you’re using electric or battery-powered models then you don’t need oil at all, at least not in the usual sense. You may not need motor oil, buy you may eventually have to apply some grease to the bearings to maintain the lubrication.
Now if you’re using a gasoline-powered motor, then you certainly need motor oil. Some of the latest commercial-grade models are now using 4-stroke engines. These have separate compartments for your gasoline and for your oil. So changing the oil is very similar to what you have to do when you own a car. Usually the manual can indicate how often you need to change the oil to ensure that your weed wacker works properly.
Then there’s the typical 2-stroke motor. This uses oil too, so that the motor is properly lubricated. However, it’s not as simple as just changing the oil every now and then.
The Oil for 2-Stroke Engines
The main thing about these 2-stroke engines is that typically they don’t have a separate container for both the gasoline and the oil. Instead, there’s just a single container. So you have to add the oil to the engine, and that’s the mixture you pour into the fuel container. Eventually the oil separates from the gasoline and it lubricates the motor properly.
Gas Oil Ratio Mix for Weed Eater
You really don’t find “pre-mixed” gas and oil mixtures, so you have to mix the gasoline and oil together. The ratio of oil gas isn’t uniform, as it depends on your particular model.
- Most weed wacker manufacturers specify a 50:1 ratio. That means you need 2.6 ounces for every gallon of gasoline.
- Other brands such as “Weed Eater” require a 40:1 ratio. That’s a mix of 3.2 ounces of oil for every gallon of gas.
- Then there’s even the 32:1 ratio. This uses 4 ounces of motor oil for every gallon of gas.
Generally, you need the 2-cycle, air-cooled engine oil for your mixture. Fortunately, you don’t have to painstakingly measure out 2.6 or 3.2 ounces from your oil container to achieve your proper ratio for the mix. You can find the oil available in 2.6, 3.2, or 4-ounce containers. Just buy the right amount for your engine.
Why Does the Mix Have to Be Right?
You have to mix correctly with the right ratio to get optimal results. If you use too little oil, then the moving parts in your motor don’t get the lubrication they need. So the friction can lead to a sudden lack of power, and then the engine will overheat. Eventually, you’ll have serious internal damage to the engine.
You may be tempted to use more oil than necessary to avoid overheating, but that’s an approach that can lead to its own set of problems. With too much oil, your machine may emit an excessive amount of exhaust smoke. In addition, you may also have problems with exhaust carbon buildup.
Do You Mix Straight into the Weed Wacker Fuel Compartment?
NO! You have to get the mix right first, and then you can pour the mix afterward. To make sure you get the mix right, you need to buy the right amount of oil (and of course, a gallon of gasoline too). You should double check the manual to make sure of the oil container size you need.
- Now you start the mix, you need a clean and empty gasoline can. Pour in all the oil from your container into the can. Now gradually ease in the gasoline into the mixture can. This mixture can has enough space to handle the addition of up to 4 ounces of oil.
- Once you’ve emptied the gas can into the mix can, screw on the cap securely. Then shake and agitate the can to encourage the gas and oil to mix thoroughly.
- Only mix enough gas and oil that you will use for the next 30 days. That’s because most gasoline products these days contain various additives that may break down the gasoline when you store it for the long term.
If you try to mix the gas and oil in the fuel tank of the weed wacker, then you’ll likely end up with a disaster. You probably won’t get the mix right since you may not be able to pour the entire 1 gallon of gas into the gas tank. Even if you somehow get the ratio right, you still won’t be able to blend the oil and gas properly.
Does your weed maker need oil? If so, make sure you provide the right amount. Without lubricating oil, the engine can malfunction in just a few minutes, and you may even end up destroying the motor completely.
