Cub Cadet Trimmer Mix Ratio

Cub Cadet is an American firm known for its outdoor equipment, particularly lawn tractors. However, the firm also manufactures a number of different varieties of outdoor equipment including trimmers, chain saws, utility vehicles and snow throwers. Several trimmer models can be found including both 2-cycle and 4-cycle. Cub Cadet’s 2-cycle trimmers vary in features and instructions, including the mixing ratio of oil and gas. The operator’s manual for your Cub Cadet trimmer lists the proper fuel-to-oil ratio for your specific model.

Mix Ratio

The precise mix ratio for Cub Cadet trimmers varies, based upon the specific model. Cub Cadet’s ST 228 2-cycle trimmer model uses a mixture of 2.6 fluid ounces of 2-cycle oil blended with 1 gallon of unleaded gas or a 50-to-1 ratio. This equates to 20 milliliters of 2-cycle oil to 1 liter of gas. The Cub Cadet BC 210, on the other hand, needs a mixture ratio of 40 to 1, or 3.2 fluid ounces of 2-cycle engine oil to 1 gallon of unleaded gas.

Gas Considerations

When mixing fuel for a Cub Cadet 2-cycle engine, it is important to use the correct gasoline for the engine. Many of the fuels found today at gas stations contain gas and oxygenates like ethanol or methanol. Oxygenated fuel has the capability to absorb water, which will create the gas and 2-cycle oil to separate. While it may be inevitable to find non-blended fuel, do not use a fuel which contains over 10 percent ethanol, since it can harm the engine of their Cub Cadet trimmer.

Mixing Considerations

Always mix the fuel and 2-cycle oil in a separate container that is labelled to hold gas; do not mix the oil and fuel directly into the fuel tank of the Cub Cadet trimmer. When storing mixed gas and oil for use later, store it in a secure location rather than for more than 30 days. Prior to fueling the trimmer, agitate the gas and oil mix to make sure it’s properly mixed.

Oil and Additives

Cub Cadet recommends utilizing their new 2-cycle oil to get their 2-cycle trimmers. The oil contains an additive which prevents rust and gum residue. If you cannot locate Cub Cadet 2-cycle oil, then choose a 2-cycle oil designed for air-cooled engines with a gas stabilizer. Mix 0.8 oz of fuel additive a gallon of fuel when mixing the oil and gas mix.
