AMSOIL SABER Professional Synthetic 2-Stroke Oil - One oil for all your equipment

Simplifying Two-Stroke Oil Mix Ratios

Two-stroke mix ratios apply to two-stroke engines that require oil and gas to be pre-blended. This is as opposed to two-stroke motors that inject oil into the motor, for example, many snowmobiles and more current outboard engines. The blend proportion is the extent of gas to oil, expressed as a proportion or a mix ratio. For example, 50:1 means 50 parts gas to 1 part oil.

To calculate mix ratio of 32:1, One gallon of gas contains 128 ounces. Take the number of ounces in a gallon of gas and divide by the mix ratio. 128 (oz) divided by 32 (mix ratio) = 4 oz of two stroke oil. Same calculation can be used for other mix ratios.

The chart below shows the proportions and container sizes for the most common mix ratios in ounces of oil per gallon of gasoline. (e.g. 32:1, 40:1 and 50:1) Chart also includes the AMSOIL SABER® mix ratio of 80:1 and 100:1.

How To Mix Gas With 2-Stroke Oil?

  • Into a clean gas can, pour the correct amount of 2-stroke oil.
  • Next, pour the correct amount of gasoline into the gas can.
  • No need to stir or shake the gas can since the 2-stroke oil will have been mixed into the gasoline. However, if the two steps above are reversed then stir the contents in the gas can, or give the can a good shake.
  • Gasoline degrades over time, try to use the mixed gas in the next 30 days. If this is not possible, add a fuel stabilzer to extend the gasoline life. Another option is to use a 2-Stroke oil that contains a fuel stabilizer.

The next chart shows the proportions and container sizes for the most common mix ratios in milliliters of oil per liter of gasoline. To calculate mix ratio of 32:1, One liter of gas contains 1000 ml. Take the number of ml in a liter of gas and divide by the mix ratio. 1000 (ml) divided by 32 (mix ratio) = 31.25 ml of two stroke oil. Same calculation can be used for other mix ratios.

Warnings To Consider

Do not use passenger car motor oil for 2-Stroke mix. This 4-stroke motor oil contains additives that can cause damage in 2-cycle engines and most importantly is not designed to be mixed with gasoline. Try to avoid using gasoline that contains more than 10 percent ethanol. Ethanol attracts moisture which is known as phase separation. This can affect engine performance and also internal damage due to a lean mixture condition and also degrades fuel. To combat the effects of ethanol in gasoline, use a fuel additive designed to prevent the effects of ethanol in pump gas.

Why Not One 2-Stroke Oil Mix Ratio For All Your 2-Cycle Equipment

Depending on two-stroke equipment age, brand and owner preferences, monitoring blend proportions of two-stroke oil mix ratios can be complicated. Professional lawn and landscape companies in particular experience challenges with regard to ensuring employees are using the correct pre-mix ratio.

AMSOIL SABER® Professional Synthetic 2-Stroke Oil provides a solution by providing excellent protection against performance-robbing carbon and wear at any mix ratio up to 100:1. That's correct, designed, tested and proven at a pre-mix ration up to 100:1.

Excellent performance at any mix ratio

Some operators prefer utilizing the mix ratio prescribed in their owner’s manuals, and that is prefectly acceptable. SABER Professional offers outstanding protection at conventional ratios. Check out the study to see how it performed at 50:1 in ECHO® string trimmers. Its ability to battle carbon and reduce wear help you get the greatest power and operability out of your equipment. SABER Professional also contains fuel stabilizer.

Re: ,

You can definitely use AMSOIL Outboard Synthetic 2-Stroke Oil at 50:1 mix ratio without harming your Mercury outboard. Once you are comfortable using this AMSOIL product, you can try mixing at 60:1. Replied by Tech Admin
