According to the US Energy Information Administration (EIA), the 134.83 billion gallons of finished motor gasoline consumed in the United States in 2021 contained around 13.94 billion gallons of fuel ethanol, accounting for nearly 10% of total finished motor gasoline consumption. Fuel ethanol contains a denaturant, which is used to render ethanol unfit for human consumption. Fuel ethanol must contain at least 2% denaturant by volume according to federal legislation, however the actual amount in fuel ethanol may be higher.
Ethanol is currently found in nearly all gasoline sold in the United States. The majority of ethanol blending into motor gasoline in the United States is done to comply with the requirements of the 1990 Clean Air Act (RFG Fuel) and the Renewable Fuel Standard established by the Energy Independence and Security Act of 2007. The Renewable Fuel Standard Program is administered by the United States Environmental Protection Agency (EPA).
Ethanol-gasoline mixtures are divided into three categories: E10, E15, and E85. E10 is gasoline that contains 10% ethanol. E15 is gasoline that contains 15% ethanol, whereas E85 is a fuel that contains up to 85% fuel ethanol. The majority of motor gasoline marketed in the United States has less than 10% ethanol by volume. The Midwest, which has the highest ethanol manufacturing capability, sells the majority of motor gasoline containing more than 10% fuel ethanol. The fuel ethanol concentration of gasoline is frequently indicated on gasoline dispensing pumps.
E10 can be used in any vehicle with a gasoline engine. The EPA has only permitted the use of E15 in flex-fuel and light-duty vehicles with a model year of 2001 or newer. Ethanol-gasoline mixtures up to E85 can be used in flex-fuel cars.
Ethanol has about a third of the energy content of pure gasoline. Depending on how much denaturant is added to the ethanol, the effect on vehicle fuel economy varies. Denaturant has an energy content that is roughly comparable to that of pure gasoline. When compared to gasoline that does not contain fuel ethanol, vehicle fuel economy may fall by around 3% when using E10.

Is ethanol content in 93 lower than in 87?
On my blog, I write about many types of fuel on a daily basis. However, we have not yet addressed all of your concerns. As a result, we’ll utilize this blog to discuss how much ethanol is included in gasoline of various octane levels. Let’s begin with a quick response:
In the United States, gasoline with an octane rating of 8793 or higher contains 10 to 15% ethanol. E-10 and E-15 are the names for these grades of gasoline. E-85, on the other hand, usually has a 94 or higher octane rating.
However, this does not provide a complete response to the question. We’ll go through how much ethanol is in each type of gasoline in greater detail below. We’ll also talk about why these percentages were chosen, as well as why the number has risen. We’ll also go over the amount of ethanol in E-85 and the distinctions between E10, E15, and E85. Finally, we’ll determine which gasoline is ideal for your vehicle. Continue reading!
Is premium gas lower in ethanol than regular gas?
Premium gas has the same amount of ethanol as other grades and doesn’t provide any more power or have any better additives than regular gas. It simply outperforms lower-octane gas in terms of detonation (knock). There’s nothing more to it, and there’s nothing less to it.
Although some brands use somewhat more detergent ingredient in their premium grades than in their other grades, all grades fulfill the EPA’s basic standards. What’s the bottom line? Use the octane-rated fuel recommended by the manufacturer in your owner’s manual. If your engine requires or’recommends’ 89- or 93-octane fuel, use it to get the best performance and fuel economy. There is, however, an exception to the norm.
If your automobile is designed for 87-octane gas and it knocks when you press the accelerator, try filling it with 89-octane gas to see if the knock goes away. If this is the case, continue to use 89-octane to regain power and save your engine.
Is ethanol present in Shell 91 octane?
When used with ethanol-containing fuel, many vehicles, motorbikes, boats, planes, and tools have engines that operate worse or parts that deteriorate.
Ethanol also creates a residue on valves and other parts, which can reduce performance.

Under the same brand names, all gasoline brands sell both pure and ethanol-containing gasoline.
Shell V-Power, for example, has an octane rating of 91 to 93, depending on whether or not ethanol is added.
It just varies from station to station, and whether or not to sell pure gas is entirely up to the station owner.
In fact, there is a Shell station in Madison, Wisconsin, that offers 93-octane V-Power with ethanol at most pumps but has a single pump that dispenses pure 91-octane gas for a higher price.
Yes, and it’s fairly simple to accomplish.
Fuel-testing kits are commonly available for a low price, or you can do it yourself:
- Fill a narrow jar halfway with water (an olive jar works well) and use a Sharpie to indicate the water level.
- To get a 10:1 fuel:water ratio, add the fuel.
- Shake vigorously and leave aside for a few minutes.
- Check to see if the water level has climbed higher than the mark.
- It has mixed with ethanol from the fuel if it has risen.
It’s possible, thanks to federal and state tax breaks. We buy it because we want to utilize it to fuel our vehicles. This site is useless if you want to save money on gas because it will not display gasoline prices. They change daily, and this website isn’t about saving money. It all comes down to acquiring pure gasoline for your vehicle.
Because gasoline has more free energy than ethanol, it delivers better mileage than E10 and considerably better than E85.
Gasoline has a free energy of 34.2 MJ per liter.
Ethanol has a free energy of 24.0 MJ per liter.
The free energy of E10 (10 percent ethanol) is 33.2 MJ per liter, while E85 (85 percent ethanol) is 25.6 MJ per liter.
As a result, when you use E10 instead of regular gas, your mileage drops by 3%, and when you use E85 instead of regular gas, your mileage drops by 25%.
If your engine doesn’t run as well on E10, as is commonly the case with older vehicles, your mileage will be even lower.

Is ethanol present in Shell V-Power?
You can use Shell V-Power gasoline, which contains no more than 5% ethanol. After E10 is introduced, Shell V-Power will be accessible at the majority of our service stations; just be sure to check the label when you fill up.
Is ethanol present in 94 octane gasoline?
This is critical since using lower octane fuels can cause engines to knock and ping, potentially causing damage. Is ethanol present in Ultra 94 Premium Fuel? Yes. Ultra 94, like all Sunoco fuels, includes up to 10% ethanol.
Is ethanol present in Chevron 94?
Chevron gasolines may contain up to 10% ethanol to meet BC’s Renewable Fuel Standard. Chevron Supreme Plus 94 octane is available at all Chevron stations in British Columbia and is ETHANOL FREE. Q.
Is ethanol present in 87 octane gasoline?
Ethanol (CH3CH2OH) is a colorless liquid with a clear appearance. It’s also known as EtOH, grain alcohol, and ethyl alcohol (see Fuel Properties search.) Ethanol has the same chemical formula whether it is made from starch or sugar-based feedstocks, such as corn grain (as in the United States), sugar cane (as in Brazil), or cellulosic feedstocks (such as wood chips or crop residues).
Ethanol has a higher octane number than gasoline, making it ideal for mixing. Gasoline with a minimum octane number prevents engine knocking and ensures drivability. To get the usual 87 octane, lower-octane gasoline is combined with 10% ethanol.
Ethanol, to variable degrees, provides less energy per gallon than gasoline, depending on the volume proportion of ethanol in the blend. Denatured ethanol (98 percent ethanol) has around 30% less energy per gallon than gasoline. The impact of ethanol on fuel efficiency is determined by the amount of ethanol in the fuel and whether the engine is designed to run on gasoline or ethanol.
Is there ethanol in super unleaded?
Unleaded gasoline is available in two octane ratings: 85 and 87.
The octane rating will be determined by state legislation. All major automakers have accepted this product, which contains up to 10% ethanol. In Iowa and Nebraska, this product is labeled as “super-unleaded.”
What is the name of the non-ethanol gas?
REC-90 is an ethanol-free, 90 octane unleaded gasoline mix developed for use in recreational/marine engines that are sensitive to ethanol.
It can also be used in some aircraft and automotive engines, though it has not been properly tested in automobiles or trucks.
Unlike most stations in the Plains states, which sell ethanol-free 87 octane unleaded alongside 10% ethanol 87 octane unleaded, numerous states sell ethanol-free gasoline formulated exclusively for maritime equipment and small engines.
