What To Do If You Put E85 In A Regular Car

If you’ve accidentally put E85 fuel in your regular car, don’t panic. While it’s not an ideal situation, there are steps you can take to minimize damage and prevent future incidents. It’s important to act quickly, but also cautiously to avoid further complications.

First and foremost, it’s crucial to understand the implications of using E85 fuel in a regular car. E85 is a blend of ethanol and gasoline, with a significantly higher ethanol content than regular gasoline. This means that it can cause serious problems if used in a car that’s not designed to run on it.

If you’ve accidentally filled up with E85, it’s important to take immediate action to prevent damage to your engine and other components. In the following paragraphs, we’ll outline the steps you can take to minimize the damage and prevent future incidents, so you can get back on the road as soon as possible.

Understand the Implications of Using E85 in a Regular Car

If you put E85 in a regular car, you’ll likely imagine yourself stranded on the side of the road with a sputtering engine. This is because E85 is a blend of ethanol and gasoline, and regular cars are designed to run on gasoline alone.

Using E85 in a regular car can cause compatibility concerns, such as engine damage, fuel system problems, and reduced fuel efficiency. However, there are fuel alternatives that can help you avoid these issues.

The first option is to drain the tank and fill it with gasoline. This will remove the E85 from your car’s fuel system and prevent any further damage. Another option is to use fuel additives that can stabilize the ethanol and prevent damage to your engine.

These additives can also improve fuel efficiency and reduce emissions. Whatever option you choose, it’s important to act quickly to avoid costly repairs and ensure the safety of your vehicle.

Avoid Starting the Engine

Don’t even think about starting that engine! You’ll only cause more damage.

When you put E85 in a regular car, it can cause fuel system damage due to its high ethanol content. The fuel lines, fuel pump, and injectors in your car are not designed to handle the corrosive properties of E85. If you start the engine, you risk damaging these components and causing potentially hazardous situations.

Starting the engine with E85 in the tank can cause a variety of problems. The ethanol in the fuel absorbs water from the air and can create a sludge-like substance that can clog the fuel injectors. This can lead to decreased engine performance and potential hazards while driving.

It’s crucial to avoid starting the engine and to have the fuel system flushed and cleaned by a professional mechanic to prevent further damage.

Seek Professional Help

It’s important to seek professional assistance immediately if you’ve accidentally filled your vehicle with E85. The corrosive properties of ethanol can cause significant damage to your fuel system, leading to expensive repairs and potential safety hazards. Attempting to fix the problem yourself could make matters worse and cost you more in the long run.

When seeking professional help, be prepared for potential cost implications. The process of draining and cleaning your fuel system can be time-consuming and require specialized equipment, which may result in a higher bill than a typical fuel pump replacement.

However, it’s essential to prioritize your safety and the longevity of your vehicle by seeking expert assistance as soon as possible. With the help of a professional, you can avoid further damage and get back on the road with confidence.

Do Not Attempt to Siphon the Fuel Yourself

Attempting to siphon the fuel yourself can lead to further damage and potential safety hazards, so it’s best to leave it to the professionals. Siphoning fuel requires specialized equipment and knowledge, and without these, you may end up causing more harm than good.

Moreover, siphoning fuel from your car can lead to environmental impact, fuel compatibility problems, and safety precautions that you may not be aware of. If you try to siphon the fuel yourself, you could end up damaging your car’s fuel system.

It’s possible to introduce air into the fuel lines, which can cause problems with your car’s engine. Additionally, if you don’t have the right equipment, you could end up spilling fuel all over the place, creating a safety hazard. Fuel spills can cause fires and explosions, so it’s important to take proper precautions.

Therefore, it’s best to leave the job to the professionals who have the necessary equipment and expertise to do the job right.

Take Preventative Measures to Avoid Future Incidents

To prevent future incidents, you should take proactive measures such as regularly maintaining your vehicle and using high-quality fuel.

Fuel system maintenance is crucial to ensure that your car continues to run smoothly. This includes changing the fuel filter, inspecting the fuel lines, and checking the fuel injectors. Ethanol fuel compatibility is also an important consideration. E85 contains up to 85% ethanol, which can cause damage to certain types of fuel systems. To avoid this, you should consult your car’s owner manual to determine if it’s compatible with ethanol fuel.

In addition, using high-quality fuel can help prevent future incidents. Low-quality fuel can contain impurities that can clog fuel lines and cause damage to the fuel injectors. Using a reputable gas station can help ensure that you’re getting high-quality fuel.

Finally, if you do accidentally put E85 in your regular car, it’s important to have it drained and refueled with the appropriate fuel as soon as possible to avoid any further damage to your car’s engine.


In conclusion, putting E85 in a regular car can have serious implications on the vehicle’s performance and longevity. It’s important to understand the risks associated with using this fuel and take appropriate measures to rectify the situation.

If you’ve accidentally filled your car with E85, avoid starting the engine and seek professional help immediately. Attempting to siphon the fuel yourself can be dangerous and cause further damage to your car.

Taking preventative measures to avoid future incidents, such as double-checking the fuel type before filling up, can save you time, money, and potential safety hazards. By following these steps, you can ensure the proper functioning of your vehicle and prevent any detrimental effects caused by using the wrong type of fuel.
