Where to Find Ethanol-Free Gasoline

Finding gasoline that does not contain ethanol can be challenging, especially in regions where almost all gasoline is blended with ethanol. Despite the prevalence of ethanol-blended fuels, there are still options available for those who need pure, ethanol-free gasoline. In this guide, we will explore various locations and methods to find your ideal fuel.

Common Retailers and Locations

For lawnmowers, chainsaws, and small engines, ethanol-free 2-stroke and 4-stroke petrol is available from lawnmower shops and agricultural suppliers in the UK. These locations often provide this specialized fuel, but it comes at a premium price. A 5-liter container can cost as much as ￡20.

A Google search for "ethanol-free gas" combined with your local address will likely show nearby stations that sell this fuel. Marinas typically stock straight gasoline, which is also free of ethanol. Additionally, airports with fuel stations often offer leaded avgas, which is always ethanol-free.

Specific Retailers and Stations

For those in the United States, retailers with blue-colored pumps often sell ethanol-free gasoline. Walmart, for instance, offers this fuel in many locations, making it a convenient choice. In the southern states, many stations near water bodies, such as marinas, sell ethanol-free gasoline, which boaters commonly use to protect their engines from ethanol-related issues.

The prevalence of ethanol-free premium gasoline varies by region, but you can often find it at service stations and retail stores, especially in areas with significant traffic. These stations usually have at least one type of fuel that is completely free of ethanol, making it worth paying the premium price for its use in small engines such as lawnmowers.

Australia's Ethanol-Free Fuel Market

While the United States sees almost all gasoline contain ethanol, the situation in Australia is quite different. Out of the four commonly available petrol/gasoline fuels, only one contains ethanol, and it is clearly marked as E10. This fuel is less popular, leading to many stations no longer stocking it. In contrast, Australia's ethanol-free gasoline is widely available and preferred for its purity and performance.

History and Issues with Ethanol in Gasoline

The use of ethanol in gasoline dates back over a century. Initially, it was suggested as a way to improve the anti-knock properties of gasoline, with Thomas Midgley proposing up to 20% ethanol. However, because ethanol could not be patented, the approach was not commercialized. Instead, tetra-ethyl lead was developed, which could be patented. While ethanol does have a higher natural octane rating and burns cleaner, it is less efficient and more harmful to engines in the long run.

Ethanol is not a suitable fuel for spark ignition engines due to its lower energy density. It requires more fuel to produce the same power as gasoline, and it can attract water from the atmosphere, leading to fuel dilution and corrosion. For aviation, ethanol is entirely banned as an additive, while tetra-ethyl lead still remains a legal octane enhancer.

Conclusion

Finding ethanol-free gasoline may require a bit of research and planning, but it is not impossible. Whether through specialized retailers, stations near marinas, airports, or certain types of retail stores, alternatives are available. For those who prioritize performance, purity, and the well-being of their engines, taking the time to find a station that offers this fuel will be well worth the effort.
