I made a quick excel sheet which calculates how much the aircon is costing in mpg under certain situations.
- For busy traffic city driving it is costing me just over 3mpg which is around 10% of my fuel economy!
- For sitting at 70 on the motorway it costs me just over 1mpg which is a more respectable 3%
- Anthony566, it would cost you almost 2mpg to run the aircon if sitting at 60 on the dual carriageway (which is around 4%).
I guess I should start to use my aircon less especially in town.
(these figures are assuming the aircon uses 1/20 gallon per hour as roughly indicated by the DIS)
