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 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.
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.

100 | 1.3 | 2.6 | 3.2 | 6.4 |
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.

The chart below 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.
Metric Mix (ml of Oil Per Liter of Gas |
Mix Ratio to 1 | 5 liters | 10 Liters | 20 Liters |
20 | 250 ml | 500 ml | 1000 ml |
30 | 167 ml | 333 ml | 667 ml |

Use the SABER Ratio to cut costs
In any case, some people want the ability of using one blend proportion in all their equipment. They also want to spend less on oil to cut costs. AMSOIL SABER Professional’s top-grade synthetic bases oils and advanced additives help prevent wear across all ratios, providing the ultimate in convenience, protection and value.
Its ability to cut costs while delivering rock-solid protection helps lawn and landscape professionals simultaneously boost their bottom line and build their reputation for reliably producing professional-looking lawns and grounds.
Mixing AMSOIL SABER Professional at the SABER Ratio reduces oil costs up to 50 percent compared to using a 50:1 ratio.
