Should i use ethanol free gas in my jet ski?


Owning a jet ski is all about experiencing the thrill of the open water and the wind in your hair. But with ownership comes maintenance decisions, including the choice of fuel. Should you use ethanol-free gas, or is ethanol-blended gas a better option for your jet ski? In this article, we’ll delve into the pros and cons of using ethanol-free gas and help you make an informed choice for your watercraft.

Understanding Ethanol and Its Effects on Jet Skis

Ethanol, a renewable biofuel derived from corn, is often blended with gasoline. While it’s touted as an eco-friendly option, it can pose challenges for jet ski engines. Ethanol has a propensity to absorb moisture, which can lead to engine corrosion and fuel system issues. This is particularly concerning for jet ski owners who may not use their watercraft frequently.

The Benefits of Using Ethanol-Free Gas in Jet Skis

1. Enhanced Engine Performance

Ethanol-free gas can provide better combustion and performance, as it lacks the moisture-absorbing qualities of ethanol. This can lead to smoother acceleration and improved throttle response.

2. Reduced Engine Maintenance

By using ethanol-free gas, you can help prevent issues like fuel system corrosion and clogged fuel lines, which can lead to expensive repairs and maintenance.

3. Longer Fuel Shelf Life

Ethanol-free gas tends to have a longer shelf life compared to ethanol-blended gas. This is beneficial for jet ski owners who may not use their watercraft regularly.

Considerations When Using Ethanol-Blended Gas

1. Cost-Effectiveness

Ethanol-blended gas is generally more affordable than ethanol-free gas. If you frequently use your jet ski and consume fuel quickly, the cost savings may be worth the potential downsides.

2. Ethanol Content

Ethanol-blended gas usually contains up to 10% ethanol. While this percentage is generally safe for most jet ski engines, it’s essential to be mindful of potential moisture-related issues.

How to Decide: Ethanol-Free or Ethanol-Blended Gas?

The decision between ethanol-free and ethanol-blended gas depends on your jet ski usage and priorities:

  • Choose Ethanol-Free Gas If: You’re concerned about engine performance, infrequent usage, and long-term maintenance costs.
  • Choose Ethanol-Blended Gas If: You prioritize cost savings and use your jet ski regularly.

FAQs About Using Ethanol-Free Gas in Jet Skis

1. Does using ethanol-free gas improve fuel efficiency? Yes, ethanol-free gas can contribute to better fuel efficiency due to its improved combustion properties.

2. Can I switch between ethanol-free and ethanol-blended gas? Yes, you can switch between the two types of gas, but it’s recommended to run the tank almost empty before switching to avoid fuel mixture issues.

3. Can ethanol-free gas help prevent engine damage? Ethanol-free gas can reduce the risk of moisture-related engine damage and corrosion.

4. Is ethanol-free gas widely available? Ethanol-free gas is available at certain gas stations, particularly those near recreational boating areas.

5. Are there any downsides to using ethanol-free gas? The primary downside is the higher cost of ethanol-free gas compared to ethanol-blended options.


Deciding whether to use ethanol-free or ethanol-blended gas in your jet ski involves considering factors like engine performance, maintenance costs, and usage frequency. By understanding the benefits and drawbacks of each option, you can make an informed choice that enhances your jet skiing experience and prolongs the life of your watercraft.
