I have been using aCar Pro since couple of years now. I love this app however since Fuelly bought it not much have changed. Now I'm about to move to another app (Fuelio) because aCar is lacking major feature for dual fuel vehicles
There is a huge number of vehicles with dual fuel systems in Europe. Those vehicles have two tanks. One for petrol and one for LPG. Those tanks are filled independently and fill-ups usually overlap. There is no way to log this type of vehicle accurately in regards of fuel usage and running costs.
I have been told couple of time this feature will be available in the next update. But so far nothing...
I do not have an ETA to report. At the moment, we're focusing our efforts on integrating aCar with Fuelly which is priority number one.
We're hoping to have it released later this year and then after the dust has settled we'll be able to start tackling our growing list of suggestions/feature requests.
