Simplifying Two-Stroke Oil Mix Ratios

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.

Why not one oil for all your 2-cycle equipment

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.
Two-stroke mix ratios apply to two-stroke hardware that requires 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.
The chart below shows the proportions and container sizes for the most common mix ratios. (e.g. 32:1, 40:1 and 50:1) and includes the AMSOIL SABER® mix ratio of 80:1 and 100:1.

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.

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.

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.
