Can You Mix Ethanol And Non Ethanol Gas In Car?

Can you mix ethanol and non-ethanol gas in your car? This is a common question among car owners who may be curious about fueling options or find themselves in a situation where they have both types of gasoline available. 

While it may seem like a simple solution to blend the two fuels together, there are important considerations to keep in mind before doing so. 

In this article, we will explore the potential effects of mixing ethanol and non-ethanol gas in your car and provide guidance on the best practices for fueling your vehicle.

Can You Mix Ethanol And Non Ethanol Gas In Car

Can you mix Ethanol and non-Ethanol gas in a car?

You can completely mix these two types of gasoline together without worrying too much about them damaging your engine. The burning oil due to gasoline fuel will also not appear in this case.

In fact, both ethanol and non-ethanol are two common types of gasoline for cars. The percentage of ethanol present in gasoline can be 15% in E15 gasoline and 85% with E85. 

The mixing of these two types of gasoline is perfectly fine and there are many users who have combined it, providing high performance.

Currently, most commercial fuels are mixtures of many different compounds. In which, the main yeus is gasoline and ethanol. 

This makes it easy for car users to refill the fuel tank in any area. They don’t need to worry too much about mixing ethanol with gasoline with other fuel compounds will damage the engine as well as incorrect air/fuel ratio.

And make sure your car will still work normally. It not only does not affect but also helps users to improve the grinding ability of the fuel in the engine system. 

As a result, the car can operate and operate more stably. In addition, the mixing also helps you to save significantly on gas costs.

What is Ethanol and Non-Ethanol Gas

What is Ethanol and Non-Ethanol Gas?

Ethanol and non ethanol are 2 different fuels, it can be considered as premium gas ethanol free used in cars. You can flexibly replace these 2 types of gasoline for your car. And make sure it will not clog the fuel tank and fuel delivery system. As a result, you will need to use less lacquer thinner during cleaning of these parts.


It is a fuel produced from corn and some other plants. It is renewable and widely used throughout the United States. In most gasoline containing ethanol compounds will be about 90% gasoline and 10% ethanol.

Mixing these two mixtures will help the fuel burn completely when the engine is running. With this advantage, ethanol gasoline is now commonly used in engines that require high performance: lawn mowers, chainsaws, trimmers, ….

Non ethanol

It is also known as virgin oil. Because there is no 10% ethanol like conventional gasoline, non-ethanol will improve fuel economy significantly, minimizing harmful effects on car engines. 

At the same time, the shelf life of this gasoline can be up to 6 months. You can apply it in many different devices: trimmer, chainsaw, and lawn mower.

What Happens If We Mix Ethanol And Non-Ethanol Gas In Car?

 Fuel System Corrosion

The mixing of these two gases can cause corrosion to take place. In it, Ethanol contains alcohol, it will negatively affect the car’s fuel system. This will interfere with the system’s ability to function properly over time, causing the fuel filter to clog.

Fuel economy has changed

Fuel economy changes when you choose to change between ethanol and non-ethanol. for example, when you choose to switch from ethanol to non-ethanol, you will save more than 3% in fuel use.

Engine damage

During use, you can flexibly change between ethanol and non-ethanol. When moving, the selection non ethanol gas near me is quite possible if you are using ethanol. But this frequent change back and forth can cause engine damage after a period of use.

Therefore, you should follow the car manufacturer’s recommendations for use. Do not overdo mixing these two fuels together for the purpose of improving engine performance.

Things can get out of your control if you don’t follow the rules that have been given before. This will lead to a series of consequences, seriously affecting the car engine.

What To Do If You Mix Ethanol And No Ethanol In Your Car

What To Do If You Mix Ethanol And No Ethanol In Your Car?

Your mixing of these two gas mixtures will be based on the following two criteria:

Lower Ethanol content

Mixing ethanol and non-ethanol requires you to reduce the ethanol content of your car. This will produce more harmful gases. 

Also, if you completely mix ethanol with a non-ethanol fuel, you will end up with an ethanol blend fuel. This combination will help produce less harmful emissions.

Mix the right ratio

What problems will you encounter when using gases other than ethanol? Over time, it will dissolve the residue present in the car’s fuel tank. At this point, you will face many different problems. Therefore, please balance and mix the appropriate ratio for the car to minimize the effects and possible problems.

What is Octane Rating?

The octane rating on gasoline grades is a measure of fuel stability. The higher this index, the more stable it will be. At this time, gasoline fuel will be able to resist effects such as knocking, premature ignition that occurs during combustion.

In addition, the octane number in gasoline is averaged by two methods:

  • Octane number under no-load condition
  • Engine octane number at higher engine speed

At this point, you will see the octane number formula in small letters on the yellow buttons displayed on the gas pump (R+M)/2. Typically, commercial gasoline products will have 3 octane numbers.

What gas or fuel should I put in my car

What gas or fuel should I put in my car?

One of the basic principles of car maintenance is to follow the manufacturer’s instructions. At this point, you will see the minimum octane rating required for your car. 

In addition, the book will also outline the recommendations and octane requirements you need to know. Prepare yourself a guidebook so you can take advantage of the lookup whenever you need it.


What happens if you mix ethanol with non-ethanol?

The fact that you mix ethanol and non-ethanol will not bring any danger to the car. Because it is both fuel that can be used for the vehicle. 

However, this mixing needs to be done according to the correct mixing ratio. If you switch from non-ethanol to ethanol, the fuel economy will decrease by about 3%.

Can I mix ethanol gas and regular gas?

You can completely mix ethanol with regular gas without having to worry about the car’s engine performance decreasing.

Is non-ethanol gas better for your car?

In fact, you use non-ethanol or ethanol are both commercial gasoline products. However, the use of non-ethanol will bring about 3% better fuel economy than ethanol and produce less harmful emissions.

Will ethanol damage my engine?

The use of ethanol is not dangerous to your car’s engine. But after a long time of use, it will also appear dirty and you need to clean the engine and injectors.

How long does non ethanol gas last?

The shelf life of non-ethanol can be up to 6 months.


Hopefully, the article will help you answer the question: “Can You Mix Ethanol And Non Ethanol Gas In Car?“. Mixing ethanol and non-ethanol won’t harm your car. It will help the engine run better. 

But you should not overdo it, the mixing needs to be in the right ratio to reduce the corrosion that takes place after a period of use.
