Ethanol-Free Gas: Pros & Cons, What It Is, How Long It Lasts, Can You Mix

“What does ‘Ethanol-Free Here!’ signage mean?”

You may have wondered after seeing it at a gas station or other establishment with similar signs. How does this type of substance affect your engine and mileage?

There have been several disputes concerning how beneficial non-ethanol gas versus ethanol-based is. Of course, it has its bad side. It is like every other substance in that regard. You will understand its component and their pros or cons. We’ll go through how long it lasts and if you can mix it with other elements.

What is it?

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

Despite the fact that most drivers are used to seeing this type of petrol in their routinely delivered fuel, there has been a movement in recent years. People want to bring back “pure” gasoline. Thus, this “pure” substance is becoming more frequently available due to increased demand. It often contains no additives, including the commonly found ethanol.

Does it Absorb Water?

One of ethanol’s features is that it can absorb water from dampness or other sources when let sit for some time. This is why ethanol-free is perfect for boat owners and motors like lawnmowers. Keep in mind that the ethanol petrol won’t go bad for another three months. Most car owners will go through a tank of petrol in a reasonable amount of time. It is why ethanol fuel has become a commonly embraced alternative for automobiles to minimize carbon dioxide emissions.

Why Should You Use It for Your Classic Cars

Metal gasoline tanks are common in vintage cars, and they can be leaky. If moist air enters the tank, the ethanol will absorb the moisture. It results in running issues and oxidation. It can also destroy fiberglass and rubber, which are commonly present in historic automobiles.

We recommend filling up your historic car with this petrol type to maintain it in good repair. 

Many consumers also prefer this fuel since it improves overall mileage. While the other one lowers the cost per gallon of gasoline, it also lowers the burn efficiency. It leaves less free energy for combustion and efficient movement. Over several years, a 3% drop in average mileage can mount up quickly.

This substance also has a longer shelf life than ethanol mixes. It benefits individuals “prepping” or preparing for disaster situations. It has become increasingly popular due to the unstable political and economic atmosphere. This gasoline can last up to six months, whereas a 10% ethanol combination lasts about three months at most. This makes it a better buy for those planning for possible shortages and emergencies.

Lastly, users frequently purchase it for their minor equipment needs. The other petrol combinations can damage smaller engines in lawnmowers and chainsaws. It’s also great for trimmers and other equipment. Since they cause gasoline to burn hotter, manufacturers advise owners to use a 10% or less ethanol blend to avoid damage. Otherwise, it may cause damage to the engine.

How Long does it Last

It lasts much longer than traditional blends like E10. If properly kept, this type can survive up to six months. It has a lower oxidation and evaporation resistance. E10 has a three-month shelf life. This makes it preferable for storage when compared to E10.

Can You Put it in Your Car?

Yes, this gasoline is safe for your vehicle. Most modern cars can run on this type and other fuel mixtures up to E15 (15 percent). Flex-fuel vehicles can handle up to E85 (85 percent) without issue. 

Can You Mix This Petrol and Other Gas Substance in a Car?

Apparently, yes. There are several factors that you will need to consider before doing so. Below are some facts that might assist you:

If you mix this fuel with other fuel blends, you should expect to reduce the percentage of ethanol in the gasoline. You will thin its layer in the gasoline. 

When you only add this petrol to other fuel mixtures, the result is an ethanol-mixed fuel. 

Most gasoline marketed in Canada and the United States is an ethanol blend, usually containing 10%. They improve the octane rating by blending gasoline with it. It also contributes to the reduction of carbon monoxide emissions.

Gasoline-burning cars can use 10% blended fuel. If its component level rises significantly, the engine must be modified to use this higher blend of petrol properly. Vehicles labeled “flex-fuel” can run on any gasoline blend up to 85 percent.

Maybe you’re putting other fuel mixtures into gasoline and don’t have a vehicle that’s certified as “flex-fuel.” You’ll want to be mindful not to go beyond 10%.

Where Do You Buy This Fuel?

It’s not always easy to find this type of gasoline. Jubitz has four locations in Southwestern Washington near Portland. If you are near to the area, you may visit them.

Remember that this petrol is rare to find this may not be available in your locality.


Pros & Cons: Is it Better?

This petrol is often known as pure oil. It is a fuel that can replace other fuel mixtures. Most automobiles will operate properly with a 10% blend in their gasoline. Some car drivers are moving to this type of fuel for several reasons, while others avoid it. It would be best to learn the advantages and disadvantages of utilizing this petrol. Continue reading to learn about the benefits and drawbacks of it and decide for yourself if switching to this fuel is worthwhile:

  • Less Reliance on production crops

  • Great mileage

  • Great for the engine

  • Great shelf life
  • More dangerous emissions

  • Reliance on foreign oil supplies

  • Expensive

  • Hard to come by
  • The Advantages of Pure Petrol

    • Less Reliance on Crops

    This fuel production impacts corn crop rates compared to other petrol blends made from agricultural products like corn. The maize sector must create more of this fuel as the number of drivers who use it grows. Using pure petrol relieves pressure on the maize business and reduces our reliance on agricultural output for energy.

    • Mileage Improvement

    Drivers get higher mileage when they use pure gas. Due to the sheer added ethanol, fuel 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. He’s a Senior Energy Researcher for Toyota and Ford spokesman Paul Seredynski. Even if three percent seems insignificant, it adds up over time. Pure petrol is preferable for overall mileage to regular and premium blends.

    • Less Damage to Engine

    Other combinations of E10 and E15 can harm your engine. It’s mainly if you drive an older model automobile that is not compatible with running on other blend fuels. Some drivers have complained that the rubber seals on specific sections have failed. Others may experience increased vapor pressure, leading to carburetor vapor lock. Ethanol also can draw water. This can cause rust on the interior of the car or the engine.

    • Extends Shelf Life

    Pure petrol lasts far longer than typical blends like E10. This type can last up to six months if properly stored. It is less susceptible to oxidation and evaporation. E10 has a shelf life of three months. In comparison to E10, this makes pure petrol preferable for storage.

    • Preferable for Lawn Mowers and Outdoor Power Equipment

    Other mixture fuels may damage lawnmowers and chainsaws. Outdoor equipment owners must ensure that their petrol does not include any ethanol. Otherwise, they must make sure it contains no more than 10%, especially as E15 becomes more widespread. Excessive heat and rusting can occur to these tools if exposed to too much of them. Small-engine equipment cannot handle other gasoline blend fuels in high concentrations. E15 burns substantially hotter than E10 and may overheat tiny engines. You will notice that most outdoor machine tools will come with instructions stating that you should not use blends above 10%.

    The Drawbacks of Pure petrol

    • It Can Cause More Dangerous Emissions

    This type is more damaging to the environment even though pure petrol has some advantages, particularly for individual drivers. Air pollution and global warming are both exacerbated by pure oil emissions. One of the main reasons why manufacturers blend ethanol with gasoline is this. As public awareness of global warming grows, mixed petrol and other alternative fuels become increasingly popular.

    • The Need for More Oil Supplies from Other Countries

    As our country’s reliance on oil grows, we’ve become more reliant on petrol imports from other countries. The usage of pure petrol makes us more reliant on fossil fuels in general. Petrol costs will eventually rise as a result of this dependence.

    • It Is Hard to Find

    This substance is more challenging to come by than E10 or E15. Most petrol stations will make other gasoline mixtures a top priority. Those who opt for the pure stuff may have to go out of their way to locate it. Several drivers find it challenging to devote themselves to using this type due to a lack of availability and the potential of the hassle.

    • It Is Expensive

    Yet compared to ordinary gasoline, pure petrol might cost somewhere between 10 to 15 cents more per gallon. That is if you’re lucky. It could cost as much as a dollar more per gallon. For drivers, this additional expense per gallon can soon pile up. If you choose this type, you’ll have to calculate whether the savings in mileage justify the upfront costs.

    Is it Good for your Car? 

    Definitely, yes. It isn’t harmful to your vehicle. Most modern cars can run on pure petrol and other fuel mixtures up to E15 (15 percent). On the other hand, flex-fuel vehicles can handle up to E85 (85 percent) without issue.

    Other gasoline compositions like E10 and E15 might damage your engine. It’s mainly if you operate an older model car that is not suitable to run on these types of fuels. The rubber seals on certain portions have failed, according to some drivers. Others may notice a rise in vapor pressure, which might cause a carburetor vapor lock. You may also use them to pull water. This can result in rust on the car’s interior or powertrain. Thus, I highly recommend using this fuel for your car to avoid time-by-time damage to your vehicle parts.

    Does Pure petrol Need Stabilizer?

    Suppose you have a small supply of this gasoline that you plan to consume within the next six months. In that case, you can effectively protect it without adding any stabilizer. Since gasoline is alcohol-free, it will not absorb dangerous water or moisture.

    However, it is critical to keep fuel in a sealed container at ambient temperature. In most circumstances, keep it away from direct sunlight, and 15 meters from any possible ignite sources.

    Water is the most common cause of damage. Exposure to extreme temperature changes and heat sources can quickly degrade the petrol’s composition and effectiveness.

    There’s one more thing to know. You may use pure petrol without adding stabilizers after six months. You should combine the oil and petrol just two weeks before the day you expect to utilize your machine.

    What Fuel is Harmful to your Car?

    Other gasoline containing too much ethanol is harmful to your vehicle. 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. Sensors are set in their automobiles and trucks to expect up to 10-15% ethanol levels for these folks. These sensors manage the fuel injection and timing, attempting to make everything work as it should. It depends on the premise of the fuel it burns to contain just 10-15% ethanol. 

    Suppose you own a car that does not have these sensors and accidentally put too much ethanol as fuel. In that case, you are in the worst-case scenario. Ethanol can harm your vehicle’s engine in a variety of ways.

    It may also damage components of your vehicle’s gasoline intake system. Furthermore, ethanol might damage the pump in your car. To effectively take care of these repairs and replacements, it can cost anywhere from a few hundred dollars to over $1,000.

    In this aspect, cars built after 2003 have less to worry about. However, many of us keep our vehicles for longer and longer periods. The number of vehicles older than ten years on the road is higher than ever. These automobiles have a lot more to be concerned about. That’s not all, though.

    If the ethanol concentration in your fuel is too large, it can harm your engine. One of the reasons AAA opposes the new 15% blends is this. Only the most modern automobiles are allowed to use them. Many people are unaware of the significance. There will undoubtedly be numerous instances when people may use E15 in a vehicle that cannot handle it. 

    In certain circumstances, the cost of replacing a vehicle’s engine is higher than the cost of buying a new car. The vast majority of insurance companies do not compensate for these types of damages and losses. You’re on your own if something like this happens to you.

    Therefore, ethanol-free gasoline isn’t harmful to your vehicle. Petrol containing too much of it is.
