What is ethanol free gas?

Ethanol-free gasoline, also known as pure gasoline, is gasoline that does not contain any ethanol (ethyl alcohol). Standard gasoline in many regions is a blend of gasoline and ethanol, typically containing 10%, but sometimes up to 15% ethanol (E10 and E15 respectively).

Here's what you should know about ethanol-free gas:

Pros:

• Better for small engines: Ethanol can damage or corrode certain types of small engines, like those found in lawnmowers, chainsaws, and other outdoor power equipment. Ethanol-free gas is the recommended fuel for these engines to prevent problems.
• Longer shelf life: Ethanol absorbs moisture from the air, which can lead to phase separation and the formation of harmful acids. This reduces the shelf life of ethanol-based gasoline. Ethanol-free gasoline lasts much longer without degrading.
• Potentially better fuel economy (debated): Some users report slightly better gas mileage with ethanol-free gasoline, particularly in older vehicles. However, this is not universally agreed upon and depends on various factors including the vehicle's engine and the specific blend of gasoline.
• May preserve fuel system components: Ethanol can damage certain rubber and plastic components in older fuel systems, leading to leaks or malfunctions. Ethanol-free gasoline reduces this risk.

Cons:

• Higher cost: Ethanol-free gasoline is generally more expensive than gasoline containing ethanol. The production process and lower demand contribute to the higher price.
• Lower octane rating (sometimes): Some ethanol-free gasolines might have a slightly lower octane rating than their ethanol-containing counterparts. This could be an issue for high-performance engines requiring higher octane fuel.
• Limited availability: Ethanol-free gasoline is not as widely available as regular gasoline. You might need to search for specific gas stations that carry it.
• Environmental concerns (debated): While ethanol is often promoted as a renewable fuel source, its production and use can have environmental drawbacks, including impacts on food production and greenhouse gas emissions. The environmental impact of ethanol-free gasoline also depends on the methods used to produce it.

In summary: Ethanol-free gasoline is beneficial for small engines and may offer other advantages, but it comes at a higher price and with reduced availability. Whether or not it's the right choice for you depends on your specific needs and priorities. If you're unsure, consult your vehicle's owner's manual and consider the age and type of engine you're fueling.
