Putting diesel in a petrol car is a common mistake, especially at busy fuel stations in Nigeria. Acting quickly can prevent serious engine damage and costly repairs. Travo.ng helps drivers and businesses navigate these emergencies with reliable guidance and fast support.

What Happens When You Put Diesel in a Petrol Car?

Diesel and petrol engines work differently. Petrol engines rely on spark ignition, while diesel engines use compression. When diesel enters a petrol engine:

  • The fuel system becomes contaminated
  • The engine fails to start or misfires
  • Internal components may get damaged if the vehicle is driven

This is why quick action is essential.

Signs You May Have Put Diesel in Your Petrol Car

  • Rough idling or engine refusal to start
  • Strong fuel smell
  • Smoking exhaust
  • Sudden loss of power
  • Car shutting down after starting

If you notice any of these signs immediately after refueling, stop the vehicle.

What to Do if You Put Diesel in a Petrol Car

Do Not Start the Engine

Starting the engine circulates diesel through the fuel system, increasing the risk of major damage.

Disconnect the Vehicle if Already Started

If you turned the ignition before realizing the mistake, switch off the engine immediately.

Tow the Car if Necessary

What You Should NOT Do

  • Don’t try to dilute the diesel with petrol
  • Don’t keep starting the engine “to see if it works”
  • Don’t attempt to drain the fuel yourself if you’re not trained

DIY attempts often cause more damage.
