Have you ever wanted to know if what you have been charged for filling your fuel tank is actually what you should be charged? “Fuel Check” is an app designed to be simple and quick to use. It will determine and check whether the fuel bowser has calculated the correct fuel cost given the fuel price per litre and the number of litres transferred. It will also allow you to apply any fuel discount you may receive to check that the final fuel cost at the cashier is correct. If you then wish to track the fuel economy of your vehicles in litres per 100km (L/100Km), “Fuel Check” provides a tool to do this for multiple vehicles. You will then be able to produce economy reports for all your vehicles. The fuel economy report will show the average fuel economy (L/100Km) for a given period along with all the entries for that period. This can be useful in determining if there is a developing issue with your vehicle that needs to be addressed (i.e. Requires a tune up). “Fuel Check” is an app that has the potential to save you money by either making sure that you are not overcharged when filling your vehicle or tracking your vehicles fuel economy and showing you trends that may cause you to use more fuel.
