iceberg phase 2 172
keeping the revs low , no harsh braking etc , plan ahead if that makes sense ? the harder u brake , the more momentum u lose , where as if u give plenty of time to just slow slighty etc . what mpg u getting atm ?
172 Cup
Clean your throttle body and remap the ECU, this has helped add a couple extra mpg to mine.
I used to get 50mpg in my old 1.2. Big difference from 36-38.
Not pressing the brakes is the key thing, so try and drive looking a long way ahead so you can minimise your need to come to a stop or slow a lot.
Racing line on roundabouts etc to carry more speed again to avoid losing energy is good too.
Putting in neutral on downhills will use more fuel than coasting, unless you turn the engine off, as on the over run no fuel is injected anyway, but in neutral it needs some to keep the engine running.

DCi would probably nearly double that after a remap!
Not so much fun on a trackday though of course.
You got 50mpg from a D7F? You must have been driving slow as f**k. My 1.2NA gets on average 36 to 40mpg, as does our TCE.
And yes, I also thought coasting will take more fuel as the engine will being using fuel to keep the engine running. When your in gear and not accelerating, the fuel supply is halted.
Alright ok. Happy with that then. I've worked out a tenner will get my 50 miles ish

PMSL! Dullest comment of the day.
I do about 33 miles a day half Dual Carrige way with a million roundabouts then a big town, then the rest twisty B roads. I give it a sensible amount changing at 3.5k ish on the Duals and most days give it hell on the B roads and still getting 33-34 mpg, if i drive like a granny i can get about 37 but thats just not fun, and fun is why i bought a RS instead of keeping the 1.2. Got 34mpg from that giving it hell everywhere.
You can't really compare how many miles you get to £10. The price of fuel constantly fluctuates so £10 of fuel today is not the same amount as £10 of fuel tomorrow.
I've tested this coasting rule a lot but I'm pretty certain my dci100 is more efficient accelerating on the downhill and then using as little throttle on the up hill. This is because its uses less energy to gain momentum going down the hill.
But I find on a long hill coasting in gear is more efficient IF the hill is steep enough to keep you coasting at a steady speed without slowing down to much. So sometimes it depends on the situation.

This +1
You can't "use energy", it's a transfer of energy. Going downhill you have a mixture of chemical energy from the engine combined with gravitational potential energy pulling the car down the hill transferring to kinetic energy (movement). This means the car needs to provide less energy to travel at a faster velocity as the GPE is acting in the same direction. On uphill sections, the GPE is acting in the opposite direction and pulling the car back down the hill so the engine needs to provide enough energy to cancel this out and more to pull the car up the hill hence using less fuel by accelerating down the hill to gain enough momentum to get up the hill without needing to apply extra energy to overcome GPE again.

Do you think they are accurate? I've seen that in my mates 330
And nope I don't put 10 quids in at a time I usually Brim it then run it down to notch above the red before filling again

'Coasting' in gear isn't coasting.
I normally put 30 in a week. But near end of month. A fiver or tenner is all I can afford.
Never fill it right up. Incase it dies. Then it's just more money down the drain lol
