Putting the wrong fuel in your car is a surprisingly common mistake with potentially serious consequences.
If you happen to put kerosene in a gasoline-powered vehicle, the effects can range from minor to critical, depending on how much was added and how long the engine runs with it.
Gasoline engines are designed to run on a specific type of fuel, and kerosene can cause damage to the fuel system and engine.
Kerosene has different combustion properties than gasoline, including a lower volatility which affects the engine’s performance.
When kerosene is introduced into a gasoline motor, it doesn’t burn as cleanly or effectively. This can lead to issues such as the engine producing smoky exhaust, stalling, choking, or in some cases, failing to start at all.
These symptoms can occur because kerosene does not combust properly in an engine designed for gasoline, which relies on precise fuel mixtures for smooth and efficient operation.
In the event of mistakenly adding kerosene to your vehicle’s gas tank, immediate action should be taken to mitigate the risk of damage to the environment and your car.
Stop driving as soon as you realize the error. Continuing to operate the vehicle may harm the engine and the environment due to improper combustion and emissions.
The fuel system will usually require draining and cleaning by a professional to remove the kerosene and prevent any further issues.
It’s our responsibility to avoid such mistakes not only to protect our vehicles but also to minimize potential environmental harm due to improper exhaust emissions.

Fuel Types and Choices for Your Vehicle
When we fill up our vehicle at the gas station, we’re faced with a few choices: regular gasoline, premium gas, and sometimes alternative fuels or additives. Each has different properties that affect our vehicle’s performance and fuel economy.
Regular Gasoline vs. Premium Gas
Regular gasoline is typically rated at 87 octane, while premium fuel has a higher octane rating, usually between 91 and 94.
The octane rating indicates the fuel’s ability to combust properly within the engine.
Using regular gas when your car requires premium can lead to knocking and pinging noises, which may damage the engine in the long run.
Conversely, if your car is designed for regular gasoline, using premium won’t necessarily improve performance or fuel economy.
It’s essential to know what your car manufacturer recommends.
| Fuel Type | Octane Rating | Recommended Use |
| Regular Gasoline | 87 | Most vehicles |
| Premium Gas | 91 – 94 | High-performance engines |
Alternative Fuels and Additives
Alternative fuels like E85, which is a blend of ethanol and regular gasoline, have become more popular.
E85 can offer a more eco-friendly option and it has a higher octane rating, which means it can provide some benefit to performance.
However, not all vehicles are equipped to handle E85 and using it in a non-compatible vehicle can harm your engine.
Similarly, additives tend to promise improved fuel economy or cleaning action, but we should be cautious since some may not live up to the expectations and can even cause damage to fuel lines and sensors.
Fuel System Components and Maintenance
In maintaining your car’s fuel system, it’s crucial to ensure that all components function optimally to prevent fuel contamination and maintain engine performance.
Role of Fuel Injectors and Pumps
Fuel injectors and pumps are heartbeats of our vehicle’s fuel system.
Injectors have the precise job of delivering fuel to the engine – a mist finely sprayed for optimal combustion.
Conversely, the fuel pump reliably sends fuel from the tank to the engine.
The fuel pump, usually electrically driven in modern cars, maintains a constant flow.
Pumps can wear out or clog, especially if improper fuel like kerosene is introduced, causing inefficient fuel delivery.
We regularly check pumps for pressure and flow to ensure they’re up to spec.
Identifying Common Fuel System Issues
Using incorrect fuel like kerosene can cause extensive damage to the fuel system.
Observing the fuel system, we look out for symptoms of trouble – hesitation during acceleration, a rough idle, or a sudden decrease in fuel efficiency.
These can be signs that our fuel injectors are clogged, or our fuel pump or fuel filter is failing.
Fuel lines also play a crucial role, and any leak or crack can lead to contamination and reduced engine performance.
A diligent maintenance routine helps us spot these issues before they escalate.
Regular maintenance of the fuel filter, replacement when necessary, and inspection of the fuel lines for signs of wear can prevent contamination.
By keeping these components in check, we ensure the longevity and efficiency of our vehicle’s fuel system.
Impact of Fuel Quality on Engine Performance
The right fuel is like optimal nourishment for your car’s engine, directly influencing its performance and power output. Our discussion will revolve around the consequences of using incorrect or contaminated fuel and how the right fuel selection can optimize engine functions.
Effects of Wrong or Contaminated Fuel
Engine Misfires and Knocking: When kerosene or another incorrect fuel enters a diesel engine, power output declines due to improper combustion. Misfires often occur as the engine’s electronic control unit (ECU) cannot correctly adjust the fuel-air mixture, leading to reduced engine performance. Knocking is another adverse effect, causing stress on engine components, particularly on the cylinders.
Wrong fuels like kerosene lack essential lubricants found in diesel, increasing the wear on fuel injectors and possibly leading to costly repairs. This mismatch can also clog fuel filters, further diminishing engine efficiency.
Optimizing Performance with Proper Fuel Selection
We recognize that each vehicle design accommodates a specific type of fuel.
Selecting the proper fuel ensures peak engine performance, as the ECU is programmed to maximize the use of the tailored fuel-air ratio for the fuel type it’s designed for.
| Fuel Type | Potential Issue | Impact on Engine |
| Kerosene in Diesel Engine | Poor lubrication, low cetane number | Reduced power, potential engine damage |
| Gasoline in Diesel Engine | Contaminated fuel, improper combustion | Engine knocking, misfires, sensor damage |
Using the recommended fuel, be it premium or regular, diesel or petrol, we ensure smoother operation and sustain the integrity of the engine.
This meticulous approach to fuel selection is key to maintaining both power and performance over your vehicle’s lifespan.
Dealing with Fuel-Related Issues
When kerosene is mistakenly added to a vehicle’s fuel system, it can lead to a range of issues, particularly for gas engines. We must act promptly to minimize the risk of extensive damage.
Steps When Fuel Problems Occur
Immediate Measures:
- The moment you realize the mishap, turn off the engine to prevent kerosene from circulating through the system.
- Do not attempt to start the car or continue driving, as this will increase the risk of engine damage.
Kerosene in the fuel system can hinder proper combustion, affect spark plug function, and potentially cause reduced vehicle performance or engine damage. Smoking exhaust is a telltale sign that the fuel mixture is incorrect.
Professional Services and Immediate Action
When faced with fuel contamination, a mechanic’s expertise is critical. Let’s understand what they’ll do to resolve it:
| Professional Service | Action Required |
| Inspection and Assessment | A mechanic will assess the extent of potential engine damage. |
| Draining Contaminated Fuel | They’ll drain the fuel tank and clean the fuel lines. |
Do not delay taking immediate action.
The longer the contaminated fuel remains in the system, the higher the chances of sustaining serious engine damage.
Taking quick steps to get to a professional can save us time and money, and helps ensure that our vehicles remain reliable.
After the contaminated fuel is removed, our mechanic will advise us if more extensive repairs are needed.
