Why or Why Not?

Most of the premium gas at Sam’s Club comes with ethanol. Ethanol is a standard ingredient in most of the gasoline in the United States today.

In fact, over 98% of US gas contains ethanol. More specifically, most gas contains a 90% gasoline to 10% ethanol ratio which helps to oxygenate the fuel and reduce air pollution.

Even though most of the gasoline today has ethanol, there are some locations that sell 100% gasoline. 100% gasoline is free from ethanol, and it is clearly marked at the gas station. Any gasoline that is free from ethanol will say something like, “100% gas” or “Non-ethanol gas” on the pump.

So, how does this information pertain to Sam’s Club premium gas specifically?

Simply put, Sam’s Club regular premium gas contains ethanol unless it specifically says otherwise. Most Sam’s Club premium pumps contain ethanol.

If nothing is stated on the pump other than the fact that it is a premium grade, then the gas contains ethanol.

Non-Ethanol vs Premium

It’s important to note that the title “Premium Gas” has nothing to do with the ethanol content. Premium gas has a higher octane rating than unleaded gas.

Premium gas typically has an octane rating of around 91, whereas unleaded gas has an octane rating of around 87.

Ethanol is not related to the octane rating in any capacity. As such, there can be non-ethanol and ethanol varieties of premium gas. If you find 100% non-ethanol gas, you will also have to look at the octane rating to determine if you are dealing with premium gas.

It is possible to have 100% non-ethanol unleaded gas, just as it’s possible to have 100% non-ethanol premium gas.
