ALT Posted May 6, 2009 Share Posted May 6, 2009 Shown below is just over 12 months of mpg data calculated from the odometer reading and the number of litres added at each fill up. Averaging at 25.1mpg. I seem to be getting lower values recently - perhaps my right foot is getting heavier Quote Link to comment Share on other sites More sharing options...
bernmc Posted May 6, 2009 Share Posted May 6, 2009 Your car computer will do that for you though...? As long as you don't reset it or disconnect the bat for long. Think ours is sitting at 24-25mpg and has been for the three years we've had it. Quote Link to comment Share on other sites More sharing options...

It tracks the calculated mpg very closely, thus suggesting it is quite accurate. Quote Link to comment Share on other sites More sharing options...
maestegman Posted May 7, 2009 Share Posted May 7, 2009 On a far less sophisticated level, my car reads an average of 30.4 mpg over the albeit brief time of ownership (just over a month). Interestingly, I did a return trip to London yesterday (about 300 miles) and it registered 34.6 mpg. I can certainly live with 30+ mpg - a bit of a difference from my previous car though - a 1.4 TDCi Fiesta! Have you experienced any difference when using unleaded / super unleaded juice?

Chris`I Posted May 7, 2009 Share Posted May 7, 2009 Have you experienced any difference when using unleaded / super unleaded juice? I definately have. Using Tesco 99RON over their normal stuff, I see more than the extra cost returned in better MPG. I think last time I measured it, 99RON was 1p a mile cheaper than the 95RON stuff, which is more than enough to keep me going there! I have also noticed that when I fill up with BP Ultimax or whatever it is these days, I get slightly more, but not enough to cover the 4-5p/l more it is to buy Quote Link to comment Share on other sites More sharing options...

Nice work. Quote Link to comment Share on other sites More sharing options...

ALT Posted May 7, 2009 Author Share Posted May 7, 2009 It could be interesting to know when the car was serviced and if that made any difference to the figures. Nice work. It was last serviced in the middle of March. So a bit too recent to make a useful comparison. Like everyone else, I find the long motorway trips do a lot better than the short windy trips. In fact there is a strong relationship between the recorded average speed and the recorded mpg... Quote Link to comment Share on other sites More sharing options...
ALT Posted May 7, 2009 Author Share Posted May 7, 2009 Just noticed that if I extrapolate the line I get something interesting. If I drive around at 150 mph, I should be able to get 49 to the gallon.

S1 HNK Posted May 7, 2009 Share Posted May 7, 2009 if you averaging anything over 28mpg then your not driving it hard enough! Quote Link to comment Share on other sites More sharing options...

Its certainly more fun the closer you get to 20 mpg. Quote Link to comment Share on other sites More sharing options...
