Misfueling is a common mistake that can lead to expensive repairs and vehicle downtime. The good news is that with a few simple precautions, you can significantly reduce the risk of putting the wrong fuel in your car. This article shares seven practical tips to help you avoid misfueling, whether you're at a petrol station or renting a vehicle.

First, pay attention to pump colour codes. In New Zealand, petrol pumps at Z Energy, BP, Gull, and Mobil often use colour coding to distinguish fuel types—green for petrol and black or yellow for diesel. Always double-check the pump label before filling. Second, look for clear signage and labels on the pump itself. Many stations have prominent warnings or colour-coded labels to help you identify the correct fuel.

Third, consider using the misfuel cap or sticker. Some vehicles have a fuel cap with a label indicating the correct fuel type. If your vehicle doesn’t, you can add a small, removable sticker as a reminder. Fourth, develop a habit of checking the fuel type before inserting the nozzle. Make it part of your routine to verify the label and pump colour each time.

Fifth, be cautious when renting cars. Rental companies often provide vehicles with clear fuel instructions. Always read the rental agreement and check the fuel cap or instructions on the vehicle. If unsure, ask the rental staff for guidance. Sixth, avoid distractions while fueling. Turn off your phone and focus on the task to prevent accidental misfueling. Lastly, if you’re unsure about the fuel type, don’t hesitate to ask station staff for assistance.

What to do right now: If you suspect you’ve put the wrong fuel in your vehicle, the most important step is to keep the engine off. Do not start or attempt to drive the vehicle.
