Hi,
I commute 104 miles a day and as such I decided to see how easy it was to increase my MPG while still living in the real world. My commute comprises of driving two different routes, the drive to work is around 17 miles on an A road and the remainder on the M27. The return journey is Motorway and dual carriageway. This is because when I go to work at 0600 the A road is quiet but on the way home the morning route would travel through Salisbury and the rush hour traffic is stop and start so it is easier but longer to stay on the motorway/Dual carriageway.
The basic theory is to keep the car moving at a uniform speed so basically very little stopping and starting.
I tried the journey so that when I was on the Motorway and Dual Carriageway I would use cruise and stay at 70 MPH. I filled the car and reset the trip monitors. By doing the journey for the week at 70 MPH the car was averaging 47.9 MPG. Not bad at all for a large saloon that is automatic.
The next week I refilled the car and reset the trip monitors but this time when on the Motorway and Dual Carriageway I set the cruise at 60 MPH. The car sits at about 1700 rpm but when I looked at the average the car was showing 59 - 61 MPG!! I will try a few weeks at 60 MPH to see what this levels out at but by simply dropping 10 MPH I have gained nearly 14 MPG!! Fantastic!!
