How Much Ethanol Is In 93 Octane Gas?

93-octane gas lies under the premium grade, the umbrella term for gases with an octane rating above 91. Fuels of different grades may have ethanol added. The main role of ethanol is to aid in the oxygenation of the gas. It leads us to the question: how much ethanol is in 93 octane gas?

We will answer this question and show you the benefits of having ethanol in gas.

What Is The Percentage Of Ethanol In 93 Octane Gas?

how much ethanol is in premium gas

Before looking at the percentage of ethanol in 93octane, it is prudent to know its significance. As mentioned, ethanol helps in the oxygenation of the fuel to see that it burns completely. In the long run, it reduces emissions and conserves the environment.

Additionally, it raises the octane rating of the gas. Octane is a hydrocarbon that does away with engine knocking when added to fuel. Some time back, the lead played this role, but its effect on health and the environment does not make it a viable choice. Here is where ethanol steps in, sometimes substituted with methanol. 

The higher the octane rating, the better the fuel is in terms of engine performance. Ethanol-free gas comes short in this area and may compress fast, leading to detonation. High-octane fuels are the go-to options for powerful vehicles, such as those with a supercharger.

Back to fuel’s ethanol content, you realize that it varies depending on the country in question. For instance, the ethanol content in gasoline US does not exceed 10%, despite being one of the largest producers of this product.

European countries have less ethanol on fuel, with areas like the UK not going past 5%. On the contrary, you will find fuel in Brazil having an ethanol content of up to 27%, which is one of the highest worldwide. Looking at the figures, you have the answers to how much ethanol is in premium gas, considering that 93 octane falls under this fuel grade.

How much ethanol is in 87 octane gas? 87 octane gas falls under the regular category and many vehicles run on it. Similar to other gasoline grades with ethanol, it has a 10% of this alcohol, as per US regulations.

How Do You Know If Gas Has Ethanol In It?

Not all vehicles run on fuel with alcohol. If you own such a car, the best move is to go for ethanol-free gas. Many reputable filling stations have this option. However, you might find yourself in the awkward situation of fuel with ethanol that leads to issues like a car not starting after refueling.

The good news is that there is a trick to pull to know if the fuel has ethanol or not. You will need a graduated measuring cylinder. One with a capacity of 50 milliliters will do fine. Additionally, you should have protective gear, such as a facemask, goggles, and gloves to handle the fuel. Ensure your working area is far from open flames to prevent a fire hazard.

You now pour the fuel into the cylinder; measure about 10 milliliters. You then add 2 milliliters of water and cover the cylinder. Shake it gently and allow the contents to settle. Ideally, you can let the mixture rest for around 20 minutes for the best outcome.

When checking your results, you focus on the point of separation. If there is no ethanol, you will see the separation point at the 2-millimeter mark, indicating the amount of water. As you know, water is denser and will settle at the bottom of the cylinder.

If the separation line is above the 2-millimeter mark, it is an indication that the fuel had ethanol. The logic is that ethanol is miscible with water; hence, it will increase its amount. 

To get the percentage of ethanol, you subtract the volume of water from the mixture, which is 2 milliliters in this case. Multiply the value you get by 10. That is the ethanol percentage in the fuel.

Always ensure that you have a clean fuel tank to curb any issues to do with impurities.

Frequently Asked Questions(FAQs)

Q: Does 93 Octane Gas Have Ethanol?

93 octane is a premium gas, meaning it has a high octane rating. To achieve this rating, there may be the implementation of measures such as the addition of ethanol. 93octane has ethanol, though some companies have ethanol-free varieties.

Q: What Gas Has Less Than 10% Ethanol?

Some countries, especially in Europe, subscribe to gas with low ethanol content. Among them is E10 gas, which falls under the regular grade with an octane rating of 87. It has less than 10% ethanol and is suitable for standard vehicles.

Q: Which Premium Gas Has No Ethanol?

If looking for ethanol-free gas near me, you may consider premium varieties. Yes, there exists premium gas with no ethanol from renowned brands like Shell and Esso. The octane rating is mostly 91.

Q: Does Sunoco 93 Octane Contain Ethanol?

Sunoco is a reputable company with its headquarters in Dallas, Texas. In its vast catalog, you will find the premium grade 93 octane gas suitable for supercharged vehicles, as it burns efficiently. It has ethanol, which helps boost its octane rating and reduce emissions in the environment.

Q: Does Premium Gasoline Have Ethanol In It?

Ethanol is a standard additive in most premium gas brands. Its main purpose is to improve the burning of the gas and reduce knocking, which comes from its detonation. In the USA, premium gasoline has a 10% ethanol content. However, you will encounter some premium-grade brands with zero ethanol content.

Q: How Much Ethanol Does Shell Gas Have?          

Shell gas contains ethanol, but the quantity will vary depending on the country. For instance, the percentage does not exceed 10% in the US. In the UK and most European countries, the value is less than 5%.

Final Words

Ethanol is a crucial additive in gasoline, with an advantage over other additives such as aromatics and lead. It performs well in efficiency and emission control. Ethanol rating varies depending on the country, with places like Brazil having 27% ethanol content in the gasoline. The rating is 10% and below in the USA, whereas the UK is a maximum of 5%.
