The automotive industry is constantly evolving, giving birth to numerous gas types. With the availability of various options on today’s market, many drivers question whether mixing no-ethanol gas vs ethanol in their vehicles is safe and acceptable. Dive into this article to dispel common misconceptions and make an informed choice at gas stations.
Ethanol Vs Non-Ethanol Gas: What Are The Differences?
True to their name, ethanol and non-ethanol gas feature distinct chemical compositions. The former is a liquid derived from sugar cane or corn grain, going through fermentation and distillation. Ethanol gas has various variants, including E85, E15, and E10. The number followed by the letter “E” represents the percentage of ethanol content when mixed with gasoline.
On the other hand, non-ethanol gas is produced from petroleum without any additives. Their distinct composition sets the stage for differences in their properties as listed below:
| Category | Ethanol | Non-ethanol |
| Gas mileage | Lower (On average, it reduces the gas mileage by 3%) | Higher |
| Corrosion-resistance | Poor (can cause corrosion) | Don’t cause corrosion |
| Emission | Fewer | Greater |
| Shelf life | Short (~ 3 months) | Long (~ 6 months) |
| Production & transportation cost | Cheap | Expensive |
| Availability | Popular | Less popular |
Can You Mix Non-Ethanol Gas With Regular Gasoline (Ethanol Gas)?
Yes, you can mix non-ethanol and ethanol (regular) gas, thanks to a minor difference in chemical composition. Most modern vehicles are designed to handle a blend of the two types safely. In fact, there is at least 10% of ethanol in gasoline sold in the US.
That said, the mixture of ethanol and non-ethanol gas is not the best practice. This habit may increase emissions and fuel consumption. Instead, stick to the fuel option recommended for your specific vehicle to ensure optimal performance.
However, if you accidentally put non-ethanol gas in your car, do not panic. It is unlikely to cause any immediate or severe damage to your cars.
Potential Risks Of Mixing Ethanol And No Ethanol Gas
Decreased Gas Mileage
Ethanol has a lower energy density than gasoline, meaning it contains fewer BTUs (British Thermal Units) per unit of volume. As a result, vehicles running on ethanol-blended fuel may experience a slight decrease in fuel efficiency compared to using non-ethanol gas alone.
Fuel System Corrosion
Remember that ethanol is a form of alcohol that can dissolve rubber and plastic. If you use ethanol gas for an extended time, the substance can corrode critical components such as gaskets, rings, fuel lines, etc.
As a result, your vehicle will suffer from leaks or clogged filters. Regardless of the situation, it hinders the engine’s performance, leading to serious damage.
Environmental Pollutions
Using solely ethanol gasoline can cut down on certain harmful emissions, such as carbon monoxide and greenhouse gasses. However, mixing it with the non-ethanol type will result in different characteristics. Depending on the specific ratio, the amount of released carbon and other harmful agents increases, leaving serious consequences for the environment.
Engine Damage
Using blended fuel can affect your car’s health in the long term, particularly if it is designed to run on a certain type of fuel. Most mechanics do not recommend blending non-ethanol and ethanol gas for older cars, as they might not be able to handle renewable biofuel.
Tips To Minimize Risks When Mixing The Two
If you are considering mixing ethanol and non-ethanol gas, here are some tips to keep in mind:
Check your vehicle’s compatibility
Most modern vehicles, especially those manufactured since the late 1980s, are compatible with E10. However, referring to your vehicle’s owner’s manual is always a good idea, or contact the manufacturer to verify the recommended fuel types and the accurate ratio for your car.
Start with a small amount
Start with a small portion of ethanol first and gradually increase the blending ratio. This approach allows you to observe any potential effects on the overall performance, fuel efficiency, and emissions to adjust the ratio accordingly.
FAQs
Is Ethanol Free Gas Good For Your Car?
There is no perfect choice, and ethanol-free fuel is no different. Consider its advantages and disadvantages for making better decisions.
Pros
- It boosts fuel economy
- It minimizes potential harm to your engine
- It has a longer lifespan
Cons
- It releases more pollutant gasses to the environment
- You must pay a higher price
- It is not always available at all gas stations
Is Ethanol In Gas Good Or Bad?
Similar to its counterpart, ethanol gas has two sides.
Pros
- It is environmentally friendly
- Users can save on their gas cost
Cons
- It may cause corrosion to fuel system components
- It reduces fuel economy
Can Any Car Use Ethanol-Free Gas?
Not all cars are designed to use ethanol-free gas. Several old models cannot operate smoothly with this fuel type, such as:
- Ford Focus 2002 – 2004
- Suzuki Cars 2008 and earlier
- Mazda 3 and 6 before 2005
- Audi A3 from 2000 and before
Conclusion
For most modern vehicles, mixing ethanol and non-ethanol gasoline is generally safe. Still, it is worth noticing the risks and considering your vehicle’s compatibility.
Remember that certain older or specialized models may have specific requirements. It is always recommended to consult your owner’s manual or contact the manufacturer to determine the suitable fuel for your car.
