Motorway driving is generally considered to give high MPG. As for your MPG problem, WiNgNuTz, try replacing your fuel filter. When my fuel filter was blocked my MPG went down from 55 to about 40. But unless there are symptoms of having a blocked fuel filter perhaps that's not the problem anyway. The best thing to do from here would be to chuck the Bosch on.
