Well I have been doing some eco driving since Saturday evening. Well almost, filled up 49 litres(lucky i got to the petrol station) then for the first ten miles i was revving quite a bit past 3000k.
Anyway after that i drove properly, didnt rev over 2500rpm, got into high gears quickly, when coming up to lights just using the brake with foot off the accelerator and then dipping the clutch when revs dropped. No speeding, highest speed was 65mph on the motorway.
Same on Sunday apart from a few instances of spirited driving
But so far 200 miles on half a tank of petrol! Best ever for my car anyway, it works.
