How to Mix Two-Stroke Oil: The Best Method

Mixing two-stroke oil correctly is essential for maintaining the performance and longevity of your engine. In this comprehensive guide, we will explore the best method for mixing two-stroke oil, focusing on the use of Amsoil Saber which can be mixed at a ratio of 100:1. This innovative approach not only eliminates gunk associated with oil buildup but also reduces the need for oil, making it a more economical choice. Additionally, we will cover the use of fuel stabilizers and upper cylinder lubricants to ensure your engine runs smoothly.

Why Choose Amsoil Saber?

Amsoil Saber is a high-performance two-stroke oil that stands out due to its ability to be mixed at a lean ratio of 100:1, compared to the more common 40:1 or 50:1 ratios specified by most manufacturers. Here’s why Amsoil Saber is the best choice for your two-stroke engine:

    • Reduced Oil Buildup: Mixing at 100:1 significantly reduces the buildup of gunk in the engine, crankcase, and exhaust.

    • Economical: Using less oil per gallon of gas translates to cost savings over time.

    • Enhanced Engine Performance: Cleaner engines run more efficiently and have a longer lifespan.

Mixing Amsoil Saber: Step-by-Step Guide

Step 1: Start with Ethanol-Free Premium Gasoline

Using ethanol-free premium gasoline is crucial as it prevents issues related to ethanol, such as water absorption and phase separation, which can harm your engine. Always ensure your fuel is fresh and stored in a clean container.

Step 2: Measure the Amsoil Saber

While the Amsoil Saber can be mixed at 100:1, many users find a comfortable balance at 70:1, especially if they are accustomed to the more common 50:1 ratio. Here’s how to measure it accurately:

    1. Use a Measuring Cup: Invest in a measuring cup with markings for 1 gallon, 1.5 gallons, 2 gallons, and 2.5 gallons. While it might not have a 100:1 mark, it will typically have a 70:1 mark.

    1. Calculate the Amount: For a 70:1 mix, you’ll need approximately 1.8 ounces of oil per gallon of gasoline. For a 100:1 mix, it’s 1.28 ounces per gallon.

Step 3: Add Star Brite Star Tron Fuel Stabilizer

Fuel stabilizers like Star Brite Star Tron are essential for preventing fuel degradation. Add one capful per gallon of gas to stabilize the fuel and improve engine performance.

Step 4: Include Marvel Mystery Oil

Marvel Mystery Oil acts as an upper cylinder lubricant and helps keep the carburetor clean. Add half an ounce per gallon of gasoline for optimal results.

Step 5: Mix Thoroughly

After adding all the components, seal the container and shake it well to ensure the oil and additives are evenly distributed throughout the gasoline.

Step 6: Use the Mix in Your Engine

This mix is suitable for both two-stroke and four-stroke small engines. For four-stroke engines like weed whackers, chainsaws, and blowers, simply add the 70:1 or 100:1 mix of Amsoil Saber as needed.

Benefits of This Mixing Method

Cleaner Engine Operation

Using Amsoil Saber at a leaner ratio ensures that your engine remains cleaner for longer periods. The reduced oil content minimizes deposits and buildup, leading to smoother operation and fewer maintenance issues.

Cost-Effective Maintenance

By mixing at a 70:1 or 100:1 ratio, you use significantly less oil, which lowers your overall maintenance costs. Purchasing Amsoil Saber in quart sizes and using a precise measuring cup further enhances cost efficiency.

Enhanced Longevity and Performance

A cleaner engine runs more efficiently, leading to better performance and extended engine life. The addition of Star Brite Star Tron and Marvel Mystery Oil further contributes to this by stabilizing fuel and lubricating the upper cylinder, respectively.

Additional Tips for Optimal Engine Care

    1. Regularly Check and Replace Spark Plugs: Clean or replace spark plugs periodically to ensure optimal ignition and engine performance.

    1. Clean the Air Filter: A clean air filter is crucial for efficient engine operation. Check it regularly and clean or replace it as needed.

    1. Monitor Fuel Quality: Always use fresh, ethanol-free premium gasoline. Stale or contaminated fuel can cause significant engine problems.

    1. Store Equipment Properly: When not in use, store your equipment in a dry, clean place to prevent moisture and dirt from affecting engine components.


By following these detailed steps for mixing two-stroke oil, you can ensure your engine runs smoothly, efficiently, and economically. Amsoil Saber offers a superior solution with its ability to be mixed at 100:1, reducing oil buildup and maintenance costs. Coupled with Star Brite Star Tron and Marvel Mystery Oil, this method provides comprehensive care for your engine, enhancing its performance and longevity.
