Reset the computer in Northampton services, set my self the challenge of getting back home (just south of Gatwick) with my best MPG so far. There were 2 of us in the car, half a tank of petrol and a boot full with suitcases so pretty heavy load for the Z. Petrol was V-Power Nitro. I honestly don't think I touched the brakes once until I pulled off the motorway close to home (must be close to 150miles). I very rarely changed lanes, stayed behind other cars for a bit of 'tow' effect. Most of the time I was aiming for 70ish mph but varied smoothly between 60 and 75. It probably sounds like the most boring drive ever but it was actually a lot of fun trying to move the throttle as little as possible and planning every move to avoid braking. The peak readout was 34.8mpg on a few long downhill stretches but I turned off the engine at home and the computer read 34.4mpg. How did I do? Im sure I could have gotten over 35mpg if I had travelled slower. What is your record for a journey (say over 100miles)?

If it was a 2.0, you did rubbish. If it was an M, then you're a true eco-warrior.
My record (3.0i) is 40.9mpg for a trip from Lincoln to Bishop Auckland.

Got 37 in my 3.0 last week. 100 miles of mixed A roads and then 50 miles on the A1. No silly driving but a few overtakes and then sitting with the traffic flow at normal speed on a very early Sunday morning...so not dawdling at 35. Very impressed after an RX8!
I tried once to drive as economically as possible and managed 51.3 mpg on a 25 miles run in town at night without much traffic mainly on a long straight road next to the beach. I mainly shifted early and drove at partial throttle. Regularly I achieve around 37-38 mpg. Decent economy from my 2.0 i believe.
In an M that's awesome. The best I've seen is 30 and the computer sits stubbornly on 26 now. That's more a reflection on it being a high days and holidays car.

It's relatively easy over short stretches, and I can get 34-35mpg, but I get bored after 5-10 minutes and the floor it, so that I end up with an mpg of less than I would have had if I'd stayed at my normal 80-85mph (GPS), 83-88mph (speedo) where I get 28mpg.
It's when you think you're doing well and then hit a long uphill stretch where you have to decide whether to labour the engine a little in 6th at 50mph or drop it to 4th/5th at slightly higher revs. Anyone know what's more fuel efficient - as anything I save on the average, means I can hoon a bit more at the weekend without spending so much on fuel.
I worked it out the other weekend that I spend about £120 a week on fuel (about 550 miles), and if I did 5mpg better by being bored out of my skull for 10 hours of driving (maybe more as the reduction in speed would cost time ∴ money), I'd only save about £15 a week.
Driving home from London to Liverpool last Thursday at 70-85mph I got 30.3mpg - but the traffic was flowing well, with no knob-ends on the road, so didn't feel the need to show my superiority to anyone.

Coming home from 'spirited' hoon around North Wales yesterday decided to crawl at 55-60 mph and travelling via A55 where i reset computer then Queensferry M56, Runcorn and M57 I managed 39.something mpg. Wonder if the car is more economical after it's been well and truly caned beforehand??

If your going to Le Mans, it will probably decrease. I went last year and it was awesome. Would have gone this year, but I'm on a stag do!
