Some brands, such as the Echo trimmers, use a 50 to 1 ratio, which means 2.6 ounces of oil for every gallon of gas. Keep in mind that the oil should be formulated and car motor oil should not be used because it can potentially damage the engine. This equals 1 gallon of gas to 3.2 ounces of oil. Most weed eaters use a 40 to 1 ratio of gas to oil.
Gas-powered trimmers use a ratio of gas to oil and it’s important to get the right combination. What is the correct mixture of gas and oil? Of course, always go with what the manufactures recommend. It is advised not to use 87 octane gas, but I know others who have done this by mistake and haven’t had issues.
You need to make sure that you are using 89 octane gas, with no more than 10 percent alcohol, which is what manufacturers recommend. If you have a weed wacker that is powered by gas, it uses a 2 cycle engine that is cooled by air and has a reservoir for gas and oil. What type of gas do you use with a weed wacker?
