Accidentally using the wrong fuel in your Volvo can cause serious problems for your vehicle. Whether it is petrol in a diesel engine or diesel in a petrol engine, this mistake can lead to costly repairs if not addressed quickly. Knowing the effects of misfuelling and how to respond can help protect your car from long-term damage.
Understanding Diesel and Petrol Engines
Diesel and petrol engines are designed to operate with specific types of fuel. Diesel fuel acts as a lubricant in diesel engines, reducing wear and tear on components. Petrol, on the other hand, is more volatile and suited to the combustion process of petrol engines. When the wrong fuel is introduced, it disrupts this process and leads to mechanical issues.
Petrol in a Diesel Volvo
If petrol is added to a diesel Volvo, the lack of lubrication can increase friction between the engine parts. This often results in damage to components such as the fuel pump and injectors. Petrol can also degrade seals and other internal parts of the engine.
Once the engine is started, you may notice irregular performance, loud noises, or smoke from the exhaust. Continuing to drive in this condition risks severe engine damage, which could lead to costly repairs or a full engine replacement.
Diesel in a Petrol Volvo
Diesel fuel is heavier and less flammable than petrol. When used in a petrol engine, it can clog filters and fuel injectors. This often leads to the engine stalling or failing to start.
If the engine does run, you might notice unusual smoke or poor performance. Over time, the presence of diesel can damage the entire fuel system, requiring extensive repairs. Prompt professional help is the best way to address this issue and prevent further harm.
Signs You've Used the Wrong Fuel
Recognizing the symptoms of misfuelling early can help minimize damage. Common signs include:
- Difficulty starting the engine.
- Unusual noises during operation.
- Excessive smoke from the exhaust.
- Poor acceleration or engine stalling.
If any of these occur after refuelling, stop the vehicle immediately and seek assistance.
Steps to Take If You Misfuel
If you realize you have used the wrong fuel, do not start the engine. Turning on the ignition circulates the incorrect fuel through the system, which can make the damage worse.
If you have already started the car, stop driving as soon as it is safe to do so. Turn off the engine to prevent further harm. Contact a professional service provider to drain the incorrect fuel and inspect your vehicle.
Preventing Misfuelling in the Future
Staying focused at the fuel pump can prevent mistakes. Always double-check the type of fuel before filling your tank. Some cars have clear labels near the fuel cap, making it easy to confirm the correct type. Avoid distractions during refuelling, such as checking your phone or multitasking.
