We’ve all been there: rushing to fill up the tank, distracted by a phone call or a thought about that upcoming deadline. In that moment of distraction, it’s easy to make a mistake, especially at the gas station. But what happens if you accidentally put the wrong type of fuel in your car? The consequences can range from minor inconvenience to a major, expensive repair. Understanding the potential damage and knowing what to do if it happens can save you a lot of trouble down the road.
The Fuel Dilemma: Why It Matters
Gasoline and diesel fuel are not interchangeable. They have different chemical compositions, designed to work with specific engine types. Putting the wrong fuel in your car can disrupt the delicate balance of your engine’s internal systems, leading to a range of problems.
Engine Damage: A Chain Reaction
Gasoline engines are designed to burn gasoline, a highly volatile liquid that vaporizes easily. Diesel engines, on the other hand, are built to handle diesel fuel, which is thicker and denser. When you put the wrong fuel in your car, the engine struggles to ignite and burn it properly. This can lead to a chain reaction of damage:
- Fuel Injectors: Gasoline injectors are designed to atomize gasoline for efficient combustion. Diesel fuel is too thick to be properly atomized, clogging the injectors and preventing fuel from reaching the engine.
- Combustion Chamber: Diesel fuel can leave behind a gummy residue in the combustion chamber, hindering the engine’s ability to ignite and burn fuel effectively.
- Piston Rings: The improper combustion of diesel fuel in a gasoline engine can cause excessive wear and tear on the piston rings, leading to oil leaks and reduced engine performance.
- Fuel Pump: The fuel pump is responsible for delivering fuel to the engine. Diesel fuel can be too thick for the gasoline pump to handle, potentially damaging the pump and leading to fuel starvation.
Performance Issues: A Rough Ride
Even if the engine doesn’t suffer catastrophic damage, putting the wrong fuel in your car can cause a host of performance issues:
- Difficulty Starting: The engine may struggle to start or crank, as the fuel doesn’t ignite properly.
- Loss of Power: The engine may lack power and acceleration, as the combustion process is inefficient.
- Rough Idling: The engine may idle unevenly or shake, indicating a problem with fuel delivery or combustion.
- Stalling: The engine may stall unexpectedly, especially at low speeds or when accelerating.
What to Do If You Put the Wrong Gas in Your Car
If you realize you’ve put the wrong fuel in your car, don’t panic. Here’s what you should do:
1. Stop Driving Immediately
The most important step is to stop driving as soon as possible. Continuing to drive with the wrong fuel can cause serious damage to your engine. (See Also: Does Car Waste Gas When Parked? Find Out)
2. Turn Off the Engine
Once you’ve stopped driving, turn off the engine to prevent further damage.
3. Call a Roadside Assistance Service
Contact a roadside assistance service or a qualified mechanic. They can help you drain the wrong fuel from your tank and refill it with the correct type.
4. Do Not Attempt to Start the Engine Again
Do not try to start the engine again until the wrong fuel has been drained and the tank has been refilled with the correct fuel.
Preventing Fuel Mix-Ups: A Few Simple Steps
The best way to avoid the hassle and expense of putting the wrong fuel in your car is to be extra cautious at the gas station:
- Pay Attention: Take a moment to carefully read the fuel pump labels before you start filling your tank.
- Check Your Owner’s Manual: Your owner’s manual will specify the type of fuel your car requires.
- Use the Right Nozzle: Make sure you are using the correct nozzle for your car’s fuel type.
- Double-Check Before Filling: Before you start pumping fuel, double-check the fuel type and make sure it matches your car’s requirements.
The Cost of a Fuel Mix-Up
The cost of putting the wrong fuel in your car can vary depending on the severity of the damage. Minor issues, such as clogged fuel injectors, may only require a few hundred dollars in repairs. However, major engine damage can result in thousands of dollars in repair costs or even require a complete engine replacement.

Frequently Asked Questions
What happens if you put diesel in a gasoline car?
Putting diesel fuel in a gasoline car can cause serious damage to the fuel system, including the injectors, fuel pump, and engine. The diesel fuel is too thick to be properly atomized and burned in a gasoline engine, leading to incomplete combustion, engine misfires, and potential engine seizure.
What happens if you put gasoline in a diesel car?
Putting gasoline in a diesel car can also cause damage, although it may not be as severe as diesel in a gasoline car. The gasoline can evaporate too quickly in the diesel engine, leading to poor combustion, engine misfires, and potential damage to the fuel injectors and fuel pump.
Can you drive a car after putting the wrong fuel in it?
No, it is not recommended to drive a car after putting the wrong fuel in it. Driving with the wrong fuel can cause further damage to the engine and fuel system. It is best to stop driving immediately, turn off the engine, and call a roadside assistance service or a qualified mechanic.
How much does it cost to fix a car after putting the wrong fuel in it?
The cost of fixing a car after putting the wrong fuel in it can vary depending on the severity of the damage. Minor issues, such as clogged fuel injectors, may only require a few hundred dollars in repairs. However, major engine damage can result in thousands of dollars in repair costs or even require a complete engine replacement.
Can I drain the wrong fuel myself?
It is not recommended to drain the wrong fuel yourself unless you are experienced in working with automotive fuel systems. Draining the fuel incorrectly can be dangerous and could cause further damage to your car. It is best to call a qualified mechanic to handle the fuel draining process.

Recap: Fueling Up Safely
Putting the wrong fuel in your car can be a costly mistake. Understanding the potential consequences and taking preventive measures can help you avoid this common pitfall. Always double-check the fuel type before filling your tank, pay attention to the pump labels, and consult your owner’s manual for specific fuel requirements. If you do accidentally put the wrong fuel in your car, stop driving immediately, turn off the engine, and contact a qualified mechanic for assistance.
Remember, a little bit of caution at the gas station can save you a lot of trouble and expense down the road.
