Are you thinking of buying a GPL or methane-fuelled vehicle or you want to turn your car by installing a system to reduce fuel consumption? Would you like to know the real savings by using one of these fuels? iFuel Economy is the application for you as it allows you to estimate the potential savings using the GPL or methane compared to conventional fuel. Enter the price of gasoline (€ / l), GPL (€ / l) and methane (€ / kg), enter the distance (for example, 1000 km), and finally the average consumption (km / l) of your car. Well ... you just have to execute the calculation! It is also possible to save both the characteristics of different cars and different prices of petrol, GPL and methane. Moreover the refuelling stations, for GPL and methane in Italy, are shown through a map and can be reached using the indications thanks to the GPS signal.
