How to Mix Oil & Gas for a Ryobi Gas Trimmer

The Ryobi gas trimmer uses a fuel mixture with a ratio of 32:1 to power the engine. The 32:1 ratio is a mix of unleaded fuel with two-cycle engine oil. It is a good idea to keep a gas can set aside strictly for fueling your gas trimmer. This will prevent accidentally placing straight fuel into your trimmer and damaging the engine. Most trimmer malfunctions are a direct result of improperly mixed fuel in the engine.

Use a clean 1-gallon gas can specifically for fueling your Ryobi gas trimmer.

Pour a 4-ounce can of two-cycle engine oil into the clean gas can.

  • The Ryobi gas trimmer uses a fuel mixture with a ratio of 32:1 to power the engine.
  • Use a clean 1-gallon gas can specifically for fueling your Ryobi gas trimmer.

Pour 1 gallon of unleaded gasoline into the gas can.

Close the gas can lid and swirl the fuel mixture around to thoroughly mix the fuel in the can.

Pour a fuel stabilizer into the fuel mixture if the gasoline you are using is a blended gas. Ryobi recommends using STA-BIL as a fuel stabilizer for the fuel mix. Use the stabilizer according to the instructions on the can.

Oil-to-gas Ratio In A Ryobi Ss30 Lawn Trimmer

You can make a 50:1 fuel ratio by mixing one gallon of unleaded gasoline -- rated at least 87 octane -- with 2.6 ounces of two-cycle oil in a container approved for storing gasoline. Gently swirl the container to ensure the products blend thoroughly. This can create air bubbles. Make only as much fuel as you can use in 30 days. You can lengthen the life of gasoline for up to six months by adding a fuel stabilizer to it at the time you buy it. Use only two-cycle oil intended for oil-cooled engines in your weed trimmer. This signals that all the fuel has been used up. The unit is then ready to be stored safely.

  • Pour 1 gallon of unleaded gasoline into the gas can.
  • Pour a fuel stabilizer into the fuel mixture if the gasoline you are using is a blended gas.

Warning

Gasoline is highly flammable. Always stop the trimmer and allow the engine to cool before adding fuel. Never mix fuel directly in the Ryobi gas trimmer fuel tank
