When mixing 2 stroke (2 cycle) fuel the mixture is expressed as a ratio of fuel to oil. For example to mix you use 50 parts fuel to 1 part oil. When operating a unit with a two stroke (or 2-cycle) engine, you need to ensure that you create a mixture of fuel and two stroke oil for the fuel tank. As engine materials improved and specific two-stroke oil were developed, fuel-oil ratios became leaner, and a ratio became common for many powersports.
Manufacturer's instructions regarding the correct mixing ratios can be found in the engine manufacturer's handbook or the owner's manual. The 2 stroke mix ratio. Most STIHL gasoline-powered equipment runs on a mixture of gasoline and 2-cycle engine oil. Knowing the proper way to mix your fuel is the first step. Two stroke fuel is basically unleaded petrol mixed with 2 stroke oil. The oil to fuel mix ratio should be specified in your engines instruction manual.
Most newer 2-cycle engines us a gas to oil ratio. Older 2-cycle engines may use a different ratio. Two common ratios for older machines is and For 2-Stroke outboards that require a premix of oil/gas we've put together the following chart to simplify the calculations. Use ONLY 2-stroke outboard. Our line of Two Cycle engine oil is designed for the specific needs of hard-working Two-Cycle engines. Two-cycle Fuel Mix is available as a or
