- Leave Space: Leave some space at the top of the container to avoid spills during mixing.
3. Add the Two-Stroke Oil:
- Precise Measurements: Carefully measure the appropriate amount of two-stroke oil using a measuring cup.
- Pour Gradually: Add the oil to the gasoline slowly, making sure it mixes well.
4. Mix Thoroughly:
- Shake or Stir: Shake or stir the container vigorously for at least 30 seconds to ensure the gasoline and oil are completely blended.
- Check for Consistency: The mixture should have a uniform appearance with no visible oil droplets.
5. Store Properly:
- Label the Container: Clearly label the container with the date and the fuel ratio to avoid any confusion.
- Keep It Secure: Store the mixed fuel in a cool, dry, and well-ventilated place.
Safety Precautions
Mixing gas requires utmost care. Remember these safety precautions:
1. Personal Protective Equipment:
- Gloves: Wear protective gloves to prevent skin contact with gasoline.

Frequently Asked Questions
What is the correct gas mixture for my lawnmower?
The correct gas mixture for your lawnmower is typically a 50:1 or 40:1 ratio of gasoline to two-stroke oil. This means that for every 50 parts gasoline, you will need 1 part oil. However, it is crucial to refer to your owner’s manual for the specific ratio recommended for your model. Ignoring these recommendations can lead to engine damage, costly repairs, and even safety hazards.
Why is it important to use the correct gas mixture?
Using the correct gas mixture is crucial for the proper functioning and longevity of your lawnmower engine. The oil in the mixture lubricates the moving parts inside the engine, preventing friction and wear.
