as per the trip counter which was pressed when i tanked the car, I managed to get 327 miles from full to the first 'bong' - that's driving it on "running-in" style driving, trying to keep the revs down and on mainly town roads with stop/start at traffic lights, junctions and stuff. i think i may have even been driving on basic Asda semi-skimmed
I think after the engine has been run in, it will get a bit more efficient.
I think 400 miles could be quite easy as long as you
- use motorway at constant speed in 6th gear and minimal use of brake
- don't carry fat passengers
- turn off the heater
- watch the tyre pressures
Yes it is pretty boring to drive like that, but with fuel prices sky high and looking like they are on the increase, saving pennies now will all add up. That's the way I see it anyway. I guess if you do want to floor it the odd time that's up to you.
