Many drivers commit the frequent error of filling up a diesel vehicle with petrol. If left untreated, it may result in serious harm to the car’s engine and other parts.  Petrol and diesel are two different types of fuel that have different chemical compositions and properties. Petrol is a lighter fuel than diesel, and it ignites more easily. Diesel, on the other hand, is heavier and more viscous, and it requires more pressure and heat to ignite. The two fuels are not interchangeable, and putting petrol in a diesel car can have severe consequences.

The effects of putting petrol in a diesel car can vary depending on the amount of petrol added and the engine’s type. In general, the more petrol that is added, and the more severe the damage can be. 

Here are some of the effects that can occur:
  • Fuel system damage: 

When petrol is added to a diesel car, it can damage the fuel system components such as the fuel pump, injectors, and fuel lines. Petrol acts as a solvent, which can cause rubber and plastic components to break down and become brittle. This can cause leaks, blockages, and other problems in the fuel system.

  • Engine damage: 

Petrol is not a lubricant, and it does not provide the necessary lubrication for the engine’s moving parts. This can cause excessive wear and tear on the engine components, leading to damage and potentially catastrophic failure.

  • Emissions: 

Petrol has a higher octane rating than diesel, which means it burns more cleanly. When petrol is added to a diesel car, it can increase the emissions and cause the car to fail emissions tests.

  • Performance issues: 

Petrol and diesel have different combustion characteristics, and mixing the two fuels can cause the engine to run poorly. The car may experience reduced power, decreased fuel efficiency, and other performance issues.

If you realize that you have put petrol in a diesel car, the first thing you should do is not start the engine. Starting the engine can circulate the petrol through the fuel system and cause further damage. Instead, you should immediately stop the car and call for assistance.

Depending on the amount of petrol added and the engine’s type, you may need to have the car towed to a garage for repairs. In some cases, the fuel system may need to be drained, and the components may need to be replaced. The engine may need to be rebuilt or replaced in extreme cases.

The best way to avoid putting petrol in a diesel car is to avoid it at all costs. Here are some pointers to help you avoid making this mistake:

Check the fuel pump:

Before filling up, check the fuel pump to make sure it is labeled as diesel. If it is not labeled, ask the attendant to confirm that it is diesel.

  • Be mindful of the nozzle size:

 Petrol nozzles are generally smaller than diesel nozzles. If you find that the nozzle is not fitting correctly, do not force it. Instead, double-check that you have the correct nozzle before proceeding.

  • Double-check the fuel type: 

Before starting to fill up, make sure that you have the correct fuel type selected. Many cars have fuel type indicators near the fuel filler cap, so be sure to check this before starting to fill up.

  • Be aware of distractions: 

Filling up a car can be a routine task, but distractions can occur. Make sure to stay focused while filling up your car, and avoid using your phone or engaging in other activities that can distract you.
