My best mpg EVER..

Yeah, if you were coasting with the stick in neutral or with the clutch depressed, it would need to idle which would burn fuel.

If you drive like a normal person with the car in gear and with the gear engaged, it won't burn any fuel if you lift off the accelerator totally.
 
All good points, but if I coast, although I'm burning fuel, I'll 'roll' further/faster because when I simply take my foot off the accelerator the engine starts to slow my car down noticeably.
 
I can't think of many situations where i'd 'want' to be coasting that don't involve me slowing down anyway, so i'm not sure that's really a huge problem is it?

There are a number of roads near me where if you put it in neutral at the start you will maintain speed for ages without needing to use the accelerator, if you were in gear you would need to depress the throttle to maintain your speed.

Yup, this is why coasting isn't even more economical :p

Yeah that was the point I was going to make, if the OP meant that. A lot of people think it saves fuel but it doesn't really (unless you fail in using the right gear) and isn't exactly safe for most people.

Just turn your engine off, then it can't use fuel. :)

For maximum economy, remove the keys from the ignition too.

If it was in 5th though, how much would you need to depress the accelerator and would it in fact use more fuel than forcing the car to idle?

I suppose it depends on the road but I can't think of anywhere round here where you'd use less petrol coasting along in neutral idling compared to holding a constant speed in top gear.

Travelling at 60 mph on a road which is, overall, downhill but is composed of many up and downs driving in a shopping trolley with a low 5th gear means that it is more economical to be in neutral rather than on the throttle the whole way down. Als it's more fun to coast :p
 
i used to get around 47mpg out of my old fiesta doing 10 min drives to and from work.

my dad gets 60mpg in his 2.0 audi A3SE TDI(or what ever letters it is) up and down the motorway quite easily.
 
pfft 40 mpg over the last 15000 miles out the vectra taxi

this includes lots of time spent idling on cold mornings and is made up of 90% local trips to tesco and ferrying junkies around the schemes of glasgow
