Simplifying Two-Stroke Oil Mix Ratios

Depending on two-stroke equipment age, brand and owner preferences, keeping track of two-stroke oil mix ratios can be complicated. Professional lawn and landscape companies in particular face challenges when it comes to ensuring employees are using the correct mix ratio.

One oil for all your equipment

AMSOIL SABER® Professional Synthetic 2-Stroke Oil helps solve these problems by providing excellent protection against performance-robbing carbon and wear at any mix ratio up to 100:1.

Two-stroke mix ratios apply to two-stroke equipment that requires oil and gas to be pre-mixed. This is in contrast to two-stroke engines that inject oil into the engine, such as many snowmobiles and newer outboard motors. The mix ratio is the proportion of gas to oil, expressed as a ratio. For example, 50:1 means 50 parts gas to 1 part oil. The chart below shows the proportions and container sizes for conventional mix ratios (e.g. 32:1, 40:1 and 50:1) and the SABER Ratio™ (80:1 or 100:1).

Excellent performance at any mix ratio

Some operators prefer using the mix ratio recommended in their owner’s manuals. SABER Professional offers outstanding protection at conventional ratios. Check out how it performed at 50:1 in ECHO® string trimmers. Its ability to fight carbon and reduce wear help you get maximum power and operability out of your equipment.

Use the SABER Ratio to cut costs

But some people want the convenience of using one mix ratio 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.

  1. Can I run this oil in a old wankel artic cat and what ratio can I use without damage to my engine. parts are hard to come buy.

    1. Hi Ronald,

      Please call our Tech Services Department (715-399-TECH), and they’ll be happy to help you.

      Thanks.

  2. I love Amsoil products from using it in prostock drag bikes in the late 70s to using Dominator in motocross bikes from 2003 on. Working in the ultralight industry for many years I had great success with Saber in our two stroke aircraft engines. Those engines didn’t run as hard, as hot, and only turned half the rpm of a chainsaw.
    Looking at Saber oil for Chainsaws, I’m a bit put off on the recommended mix ratios. Saying you can run 50-1 to 100-1 is a pretty large spread. Too little oil isn’t good as is too much oil will cause ring sticking and build up of carbon etc. Why so non specific? Running too little oil may not show up as a seized piston, but might wear crank bearings, and piston skirts more over time. It would be good to see a test with two Identical chainsaws running under a load for a given amount of time at 50-1 vs say 100-1. The results of a simple test like this would answer so many questions. Considering the cost of a good pro model chainsaw, it would be nice to know at what ratio is too rich with too much buildup vs too lean showing added wear.. Somewhere in the middle we would find that answer.

    1. Hi Brian,

      Thanks for using our products. We’ve tested SABER Professional in our mechanical lab and in the field at 50:1 and 100:1 in different types and brands of two-stroke equipment, including string trimmers and backpack blowers. Time and again SABER Professional proves that it resists carbon buildup and wear at either mix ratio. In fact, check out how it compares to ECHO Power Blend. We’re also close to publishing a technical study that compares SABER Professional at 100:1 to ECHO Power Blend at 50:1. It should be ready in March, so check back to our blog or http://www.amsoil.com then.

      The bottom line is this: the oil is proven to work well at either mix ratio. If your manufacturer calls for 50:1 and you feel comfortable running that mix ratio, use 50:1. But, if you want to spend 50% less on oil without sacrificing cleanliness or power, use 100:1. It’s your call.

      By the way, I passed on your suggestion of testing in chainsaws to our Product Manager in charge of SABER Professional.

      Thanks again.

  3. This is excellent table. I would like to see if you include the table with liters and correct mixture with ml as in Canada we are using liters and not a gallons, this will help us to use exact mix without calculations into metric.

    1. Slavko, it’s great to hear from Canada. Thank you for the feedback, I’ll post a metric version of the table and you should see it by the end of the week.
