How to use our Petrol Calculator
Our petrol calculator is super-easy to use. All you need to do is enter these details into the calculator:
I need to drive: Enter the distance you need to drive in this box. For example, if you need to drive 100 miles, just enter figure 100.
Miles or Kilometres: Choose the measurement you require. The calculator is set to miles by default. It’s very important that you choose the correct measurement because this will affect the calculations for the price and the quantity of fuel required.
My car’s MPG: Enter the MPG of your car into this box. If you don’t know your car’s real MPG, you can use our MPG calculator to work this out.
Petrol price (Pence): Enter the price you’re paying per litre of petrol, in pence. For example, 172 or 175.
Round trip required: Choose whether or not you would like the petrol calculator to include a return cost. If you choose yes, this will double the price and fuel quantity automatically.
