Have you ever accidentally put diesel in a gasoline engine? We’ve all made mistakes – and this is one of them. While it may seem like an innocent mistake, putting diesel fuel into a car that runs on gasoline can cause serious damage to your vehicle.
From structural damage to costly repairs, the consequences may be far more severe than you would expect. In this blog post, we’ll explore what happens if you put diesel in a gas car and how to prevent such accidents from happening in the future.
Diesel vs Regular Gas: The Basics
When it comes to fuel for your car, the choice between diesel and regular gas may seem puzzling. Diesel fuel, derived from petroleum, is crafted for diesel engines and packs higher energy levels compared to regular gas.
This means it can deliver more power and torque—making it a prime choice for vehicles requiring substantial engine output. Diesel’s higher flash point makes it less prone to unexpected ignition when encountering high temperatures. Also, diesel is denser than regular gas.
On the other hand, most vehicles rely on regular or unleaded gas. Unlike diesel, regular gas is a concoction of various hydrocarbons, designed specifically for spark-ignition engines. Though it has lower energy levels than diesel, it’s more susceptible to combustion if exposed to elevated heat due to its lower flash point.

What Happens If You Put Diesel In A Gas Car?
When diesel enters a gas car’s engine, it doesn’t combust properly. Gas engines rely on spark plugs to ignite the fuel-air mixture. However, diesel has a higher flashpoint and needs high compression to ignite. In a gas engine, the diesel fuel won’t ignite, leading to misfiring or, in some cases, it might not start at all.
The immediate consequence is the clogging of the gas car’s fuel system. Diesel is denser and oilier compared to gas. When it enters the fuel injectors and the combustion chamber of a gas engine, it leaves behind residues that can clog the system. This can lead to the engine running rough or stalling.
Moreover, if the car is started and driven with diesel in its system, it can cause significant damage to the engine. Diesel can act as a solvent, stripping away the oil that lubricates the fuel injectors and pump. Without lubrication, these parts can suffer significant wear and tear.
The cost of rectifying the mistake could be high, especially if the car was driven for a longer period. This would involve draining the entire fuel system and cleaning out the residues. In worst-case scenarios, parts of the engine may need to be replaced, turning a simple mistake into a costly affair.
Nevertheless, it’s worth noting that the impact is not as dire if the diesel is mixed with gas. If there’s more gas than diesel in the tank, the engine might run poorly, but it would not cause as much harm as pure diesel would. However, it’s always best to avoid mixing fuels.
In summary, feeding diesel to a gas car can lead to serious issues, ranging from a rough-running engine to extensive engine damage. It’s important to pay attention when refueling, ensuring that the right type of fuel goes into your car.
What Should You Do if You Put Diesel in Your Car?
If you’ve accidentally filled your car’s gas tank with diesel, don’t panic. First and foremost, avoid starting your car. The damage starts once the diesel circulates through the system. Hence, the fewer the engine turns over, the less damage it will cause.
Contact a professional right away. Many roadside assistance services provide a fuel removal service. They can safely drain the diesel from your gas tank and flush the system. It’s crucial to not attempt this yourself as improper handling of fuel can pose safety risks.
If you’ve already started the car and driven a bit before realizing the mistake, stop driving as soon as possible. Depending on how far you’ve driven, you may have to get your fuel system cleaned and possibly replace the fuel injectors and fuel pump.
Remember, it’s always better to prevent such a mistake from happening. Always check the fuel type before filling up your tank. If you’re unsure, refer to your car’s user manual or consult a professional.
Lastly, keep in mind that this isn’t a common mistake. Diesel nozzle sizes are typically larger than those for gasoline, making it difficult to insert a diesel nozzle into a gas car’s tank. However, misfuelling can still occur, especially at unfamiliar gas stations or when you’re not paying attention. Always take an extra moment to ensure you’re using the right fuel.
In conclusion, putting diesel in a gasoline car can lead to significant damages and costly repairs. It’s essential to be mindful when refuelling and to contact a professional immediately if you’ve made this error. Prevention is the best course of action, but quick response can minimize the damages if the mistake has already occurred.
It’s common to have questions about the potential issues that can arise when diesel fuel is accidentally put into a gasoline engine. In this section, we will address some of the most frequently asked questions regarding this topic to help you understand the situation better and how to handle it.
What are the first signs if I’ve put diesel in a gas car?
If diesel fuel has been added to a gasoline tank, the engine will likely struggle to start or, perhaps, not even start at all. If the car does manage to start, it may run roughly or even stall. Diesel fuel is denser and oilier than gasoline, which can lead to clogging in the fuel injectors and combustion chamber, affecting the performance of the engine and causing it to run poorly.
Will a small amount of diesel in a gas car cause damage?
While it’s never ideal to mix fuels, a small amount of diesel mixed with gasoline may not cause serious damage to your vehicle, especially if there’s more gasoline than diesel in the tank. However, the car might run poorly due to the presence of diesel. If you suspect that diesel has been mixed with gasoline in your car, it’s advisable to have the fuel tank drained and cleaned by a professional to prevent potential issues.
Can a car be driven with diesel in a gas tank?
It is strongly advised not to drive a car if diesel fuel has been added to a gasoline tank. The damage starts once the diesel circulates through the system, stripping away the oil that lubricates the fuel injectors and pump. Driving the car could lead to significant damage to the engine, which can result in costly repairs and possibly the need to replace parts of the engine.
How can I prevent putting diesel in a gas car?
The best way to prevent such a mistake is to always check the fuel type before filling up your tank. Diesel nozzle sizes are typically larger than those for gasoline, making it difficult to insert a diesel nozzle into a gas car’s tank. But extra care should be taken, especially at unfamiliar gas stations. If you’re unsure, refer to your car’s user manual or consult a professional.
The consequences of misfuelling, specifically putting diesel into a gasoline car, can be quite severe. It can lead to an array of issues, from a poorly running engine to extensive engine damage. The outcome depends largely on the amount of diesel in the gasoline and how far the car has been driven post misfuelling.
The best course of action is prevention. Always ensure to use the correct fuel type when refuelling. Pay close attention during this process, especially when using unfamiliar gas stations. If you’re uncertain, it’s better to seek help or refer to the vehicle’s user manual.
However, if the mistake has already occurred, remember not to panic. Refrain from starting the car to avoid circulating the diesel fuel in the system, which can lead to more extensive damage. Seek professional help immediately. Roadside assistance services can safely drain the diesel from your gas tank and cleanse the system.
In conclusion, being mindful during refuelling can prevent expensive repairs and potential damage to your vehicle. But, if the misfuelling occurred, the quick response and professional help can minimize the damage. It’s a rare mistake, but awareness and understanding of the consequences can help manage and prevent this from happening.
