Accidents happen, but there are a few things you can do to ensure you don't fill up your car with the wrong fuel:
1. Pay attention while putting fuel - When you get to the pump, try to avoid distractions.
2. Look at the nozzle size - The diesel nozzle is bigger than the neck of a petrol tank, making misfuelling a petrol tank more difficult. A petrol nozzle, on the other hand, fits perfectly in a diesel filler. Before pulling the petrol trigger, double-check the fuel type if the nozzle feels extra loose.
3. Fuel cap labeling - Inside or near the fuel cap, place a sticker with the name of the fuel
4. Identifying hose color - Typically, petrol nozzles, triggers, and hoses are green, while diesel nozzles, triggers, and hoses are black, but this isn't always the case. If the colors aren't clear, it is better to ask the person who manages the gas station.
5. Read pump label - Always take time to read the pump labels before fuelling.
