What Is Pure Gasoline?

What is Ethanol-Free Gas/Non-Ethanol Gas?

Non-Ethanol gasoline is a high-quality fuel without the addition of ethanol. Ethanol is a type of grain alcohol that is mixed with pure gasoline in order to be utilized in automobiles. Sugarcane, wheat, corn, barley, various grains, and high starch/sugar crops are among the feedstocks used to make ethanol.

Premium Non-Ethanol Gasoline is now available at over 280 Stewart’s locations. Classic cars and recreational vehicles such as snowmobiles, boats, and motorbikes, as well as snow blowers, lawnmowers, chainsaws, trimmers, and other similar items, benefit from Premium Non-Ethanol Gasoline’s improved performance and safer operation.

Advantages of Using Our Ethanol-Free Gas include:

  • The energy content is higher. More power = more energy
  • Gas mileage has improved (around 3-4 percent )
  • There is no reliance on ethanol crops.
  • Because ethanol attracts water, which can cause rust on an engine’s interior parts, it does significantly less damage to engines.
  • Ethanol can create vapor lock in a vehicle’s carburetor by increasing vapor pressure.
  • The engine is not corroded by it.
  • On smaller engines, this extends the projected life.
  • Producing costs are lower.
  • Reduces the use of fossil fuels.
  • Because small engines are not intended to handle high-ethanol-based gasoline, it is required for outdoor equipment.
  • For older car engines, this is the best option.
  • Prevents expensive outdoor power equipment repairs**
  • Always consult your owner’s handbook to determine the proper fuel to use.

Many of our rivals and gas stations sell non-ethanol gasoline with a 90 octane rating, whereas Stewart’s sells 91 octane PREMIUM non-ethanol gasoline. In general, higher octane levels are recommended for newer autos. Our Premium version offers optimal fuel efficiency, higher mileage performance, and is more gentler on your engine. Fill up at Stewart’s to give your engine the better gas it deserves, and don’t forget to fill up on coffee, grab-and-go food, and, of course, ice cream!!

Less Dependence on Ethanol Crops

Because ethanol is made from agricultural products like corn, ethanol production has an impact on corn crop prices. The maize business must create more ethanol-based fuel as the number of drivers who use it grows. Using non-ethanol gas relieves pressure on the maize business and reduces our reliance on agricultural output for energy.

Improves Mileage

Drivers get higher mileage when they use pure gas. Because of the added ethanol, gas mixtures like E10 and E15 contain less free energy. Regular and premium petrol can affect your gas mileage by up to 3%, according to Mike McCarthy, a Senior Energy Researcher for Toyota, and Ford spokesman Paul Seredynski. Even if three percent seems insignificant, it adds up over time. Non-ethanol gas is better for overall mileage than normal and premium gas blends.

What is the composition of pure gasoline?

) is a transparent, petroleum-derived flammable liquid that is predominantly utilized as a fuel in most spark-ignited internal combustion engines (see Etymology for nomenclature variants and local usage) (also known as petrol engines). It is primarily made up of organic compounds derived through fractional distillation of petroleum, which are then improved with various additions. Depending on the crude oil assay and what other refined products are recovered, a 160-liter (42 US gal) barrel of crude oil can generate up to 72 liters (19 US gal) of gasoline following processing in an oil refinery.

Is it possible for a car to run on pure gasoline?

This appears to be an odd question.

Is ethanol-free petrol harmful to your vehicle? Isn’t that the same gas we all used before the 2000s, when they started adding ethanol in our gas on a large scale? Yes, it is technically correct. I mean, it might not be identical (because there are all sorts of modern detergents and additives that get developed over the years). But, for the most part, it’s the same stuff.

So, why are you asking what appears to be a straightforward question? The contents of the human heart are unknown to us…. People ask these kinds of surprise inquiries all the time, after all. And it’s a question we’ve been asked before. People are accustomed to thinking of ethanol gasoline as the type of petrol they purchase. As a result, they now consider ethanol-free gas to be abnormal.

In a nutshell, no, ethanol-free gasoline is not harmful to your car. Most modern cars can run on both ethanol and non-ethanol gasoline mixtures up to E15 (15 percent ethanol). Flex fuel vehicles, on the other hand, can handle up to E85 (85 percent ethanol) without issue.

This isn’t to suggest that some types of gas aren’t harmful to your vehicle. At least one type has the potential to be problematic.

Ethanol Gasoline With Too Much Ethanol

As previously stated, if you have a flex fuel car, you can run up to 85% ethanol without issue. However, many people do not own flex fuel automobiles. For those folks, computers in their automobiles and trucks have been configured to expect ethanol levels of up to 10-15%. The computer manages the fuel injection and timing, attempting to make everything work as it should based on the premise that the fuel it burns contains just 10-15% ethanol.

However, some folks inadvertently put E85 in their non-flex car. Most of the time, they fill up with regular gas and are unaware that someone upstream (the folks who supply the gas to the gas station) has unintentionally added too much ethanol. They thought they were blending in 10%, but they may have blended in 16 percent, 18 percent, or even more than 20%. It occurs (and more often than you think). And no one knows when it happens because no one keeps track of that sort of thing.

When you put ethanol gas in your automobile with too much ethanol in it, strange things happen to the computer’s perception of what it’s seeing. The computer assumes the gas is 10% or 15% ethanol, but notices that the density (weight) of the gas and the emissions it produces don’t match up with what it thinks it’s seeing. The computer will believe the automobile is running on a “low” fuel combination (too much air and not enough fuel). As a result, the computer normally responds by injecting too much fuel (to address a problem that doesn’t exist), reducing your gas mileage and performance.

So, no, ethanol-free gasoline isn’t harmful to your vehicle. Gas containing too much ethanol, on the other hand, is not.

Is it necessary for me to use pure gasoline?


You may have noticed a few stations selling “ethanol-free” gas while driving around the Denver metro region.

It’s pure gasoline, not the corn-based ethanol found in most gas stations around the country.

Pure gas, while less popular than ethanol mixes, may be preferable for older car engines, boats, lawn mowers, and other tools.

“In general, the more ethanol in gasoline, the poorer the fuel economy,” DeHaan explained. “If you go up to E85, for example, there’s around 20% less energy in E85 than there is in 100% gasoline, therefore you’ll get a 20% worse fuel efficiency,” says the author.

Most drivers, however, utilize E10 or E15 blends, which contain 10-15% ethanol. Only about 5% of gas mileage is lost due to the ethanol content. When you consider that ethanol-free gas can cost anywhere from 30 cents to more than a dollar more per gallon, the ethanol blend will cost you less per mile.

DeHaan also mentioned that gas stations receive government rebates for selling ethanol, which lowers the price even more. Ethanol emits fewer hazardous gases and is often seen as being better for the environment.

So, what can you do if you can’t lower your gas prices by switching fuels? Driving slowly, rolling down windows instead of using the air conditioner, checking tire pressure, and keeping your vehicle as light as possible are all suggestions made by experts.

What is pure gasoline’s octane rating?

In recent years, more car manufacturers have required or recommended the use of premium gasoline (a high-octane type of fuel) in their vehicles. The price differential between premium and lesser octane types has widened as well. As a result, more individuals are interested in learning more about octane and what the numbers on gas pumps signify.

Fuel stability is measured by octane ratings. The pressure at which a gasoline would spontaneously combust (auto-ignite) in a testing engine is used to determine these ratings. The octane rating is essentially a simple average of two octane rating techniques. The main difference between the motor octane rating (MOR) and the research octane rating (RON) is the operating conditions. The more octane a fuel has, the more stable it is. In the United States, retail gasoline stations sell three different types of gasoline based on the octane level:

  • Typical (the lowest octane fuelgenerally 87)
  • Grade in the middle (the middle range octane fuelgenerally 8990)
  • High-end (the highest octane fuelgenerally 9194)

These grades of gasoline are referred to as unleaded, super, or super premium by some marketers, but they all refer to the octane rating.

Is ethanol a worse alternative than gasoline?

According to a new analysis published in Proceedings of the National Academy of Science, the process of harvesting and producing corn-based ethanol emits more hazardous pollutants than regular gasoline.

  • According to Reuters, the five-year study, which was partially funded by the National Wildlife Federation and the US Department of Energy, concluded that ethanol is at least 24% more carbon-intensive than gasoline.

What’s at stake: The findings contradict the goals of the Renewable Fuel Standard (RFS), a government program established in 2005 to cut U.S. emissions and reduce dependency on foreign sources of energy.

  • It necessitates the addition of billions of gallons of ethanol to the nation’s gasoline supply by oil refiners.
  • Furthermore, Iowa’s agricultural sector is strongly reliant on ethanol sales. The state produces half of the country’s grain, with half of that harvest going to fuel.

According to Reuters, ethanol produces more carbon emissions than gasoline due to the quantity of cropland required to cultivate maize crops and the tillage that goes along with it.

  • Corn cultivation rose by over 7 million acres in the United States as a result of the RFS between 2008 and 2016, representing a 168.7% increase.
  • According to Reuters, tilling the land releases carbon into the soil, and fertilizers also cause emissions.

The other side: According to Geoff Cooper, president of the Renewable Fuel Association, the writers of the article assembled “a series of worst-case assumptions” and “cherry-picked facts” for their analysis.

  • Past studies have shown that even with tillage, maize ethanol produces fewer emissions than gasoline, according to the association.

The big picture: As the Iowa Legislature explores implementing E-15 at gas stations, the state continues to invest big on biofuels.

  • However, its future in the United States is in doubt, as President Joe Biden expresses an interest in electric vehicles instead.

Is ethanol gasoline preferable to conventional gasoline?

Depending on the energy differential in the blend utilized, the influence on fuel economy varies. E85, for example, offers around 27% less energy per gallon than gasoline because it includes 83 percent ethanol (the impact to fuel economy lessens as ethanol content decreases). Gasoline cars, especially flexible-fuel vehicles (FFVs), have gasoline-optimized engines. Fuel economy would presumably increase as a result of increased engine efficiency if they were designed to run on higher ethanol mixes.

Ethanol also has a higher octane rating than gasoline, resulting in more power and performance. Because of its high octane, Indianapolis 500 racers frequently utilize E98 to fuel their race cars. Several ongoing efforts, such as the Co-Optimization of Fuels and Engines initiative, aim to better understand the potential for ethanol blends and other high-octane biofuels to improve engine efficiency.

Is premium petrol better for mileage?

Is it true that higher octane fuel is more efficient? In a nutshell, no. Paying more for premium fuel does not guarantee that your car will operate better or achieve better gas mileage. Giving your automobile the fuel it needs to function smoothly and efficiently while avoiding engine damage does affect your gas mileage.

What are the four different sorts of gases?

Regular gas has an octane rating of 87, with an average of 85 to 88. This is the type of gasoline you’re most likely to use. It’s also what a lot of auto companies recommend.

The 87 octane gasoline keeps your automobile running smoothly, albeit it may not provide the same level of performance as higher octane gasoline. Certain car models and manufacturers, on the other hand, demand higher octane gas, while others do not.

If you’re on a budget, normal gas is the cheapest option and will help you reach your primary goal of going from point A to point B.
