What Happens If You Put Petrol in a Diesel Car?
Petrol in a diesel engine is serious because diesel fuel acts as a lubricant for the high-pressure fuel pump. When petrol enters the diesel system, it strips away this lubrication, causing metal-on-metal contact within the fuel pump and injectors. Within minutes of running, this contact causes severe wear and can lead to complete fuel pump failure.
Petrol in diesel car, what happens next depends on whether you started the engine:
- Engine not started: Simple drainage prevents all damage, immediate call saves everything.

Tips to Prevent Wrong Fuel in Perth
Double-Check Before Refuelling
Always confirm the fuel type your vehicle requires by checking the owner's manual or the label inside the fuel cap before you start refuelling.
Use Visual Reminders
Place a sticker or tag near your fuel cap or dashboard indicating the correct fuel type. This is especially helpful if multiple people drive the vehicle.
Pay Full Attention at the Pump
Avoid distractions such as using your phone or engaging in conversation while refuelling. Take your time and focus on selecting the correct pump and nozzle.
Read Pump Labels Carefully
Don't rely solely on the color of hoses or nozzles. Always check the pump's trigger label and fuel grade indicator to ensure you're choosing the right fuel.
Consider a Misfuelling Prevention Device
Invest in an aftermarket fuel filler cap or adapter that only allows the correct nozzle to fit your vehicle's tank.
Inform All Drivers
Make sure anyone who drives your vehicle knows the correct fuel type and follows these precautions.
Avoid Refuelling When Rushed or Distracted
If you're in a hurry, stressed, or preoccupied, wait until you can give refuelling your full attention to minimize mistakes.
By following these simple steps, you can greatly reduce the risk of misfuelling and avoid the need for fuel rescue services.
