Increasing mileage efficiency. How do you do this?

almillar

The engine is stalled when you use engine braking. Fuel is not running the engine, moving along the road is. Drive along the road in gear, take your foot off the accelerator pedal - engine braking.

But its not stalled though is it. The engine is still running, there's still compression etc. 
Your point seems to be "if" you need to accelerate then there has been a waste of fuel? Is that not just reading the road and would be the case if engine braking or coaasting was used? Reading the road is one of the best ways of saving fuel.

Do you know how to bump-start a car? Push it along the road to get it to start? That's what you're doing when you're engine braking. No fuel going in = stalled, or maybe I should actually be saying stalling.

You're absolutely right, reading the the road is one of the best ways of saving fuel. Doing this well means rarely having to brake. But you can't predict everything of course, and you can't catch every green light. So having read the road, you have different tools available to you  - coast, slow down in gear (engine braking) or actually brake.

Let's say you and I are driving along a dual carraigeway round my way. We're doing the same speed (50mph) driving beside each other. I know the phasing of the lights, you don't. You use engine braking to slow to a stop at the red light. Whilst doing that, you've used barely any fuel. I know the light is going to turn green, so I coast. When you come to a stop, you've used less fuel than me. But when I am able to coast through, at say 40, and you're stopped, you have to accelerate again, from 0 to 50. I only need to accelerate from 40 to 50. I have used less fuel.

The above example is not a failing on your part as a driver - you should stop for red lights! It's just local advantage.

How can a differing opinion not be an opinion LOL and coasting life and death?? do you actually drive? and if so you really should consider giving up!

Because its not a opinion that you are not in full control of your car. Its a indisputable fact for the reasons I've given and why its quoted by authority which I am not. I do drive, I do it to the average standard. You sound like you do it just under that standard, you may never come to harm, you also may. What I do suspect is quantifiable is the fuel saving you believe you make, I suspect very strongly it is simply not worth doing.

You assume too much! 
Maybe some people are not in full control of their cars and based upon the p**s poor standard of driving I see most days I can understand why you would think that, these type of drivers wont have any interest in fuel efficiency though we cannot assume everyone is in that bracket. As a bike rider of 30 years who rides a hyper sports bike, my road senses are far more heightened than your 'average' car driver, they have to be because this is where life or death unlike coasting genuinely does exist and. These advanced senses are of course transferred over to my car driving skill set, I'm not saying I'm a better driver because I'm also a bike rider but based upon what I see on the roads I definitely am way above average. 

To clarify further I am a regular attendee of the Isle of Man TT where ironically the car drivers are much better!!, the national speed limit on the Island is NO LIMIT! where if I CHOOSE TO I can legally reach speeds of 170mph and this tests ability and skill levels, I enjoy track days too and therefore by virtue of all my riding skills, my DRIVING skills benefit, my reaction times are faster, my ability to read the road ahead and my overall road awareness is far better than most car drivers. I don't really care about fuel efficiency on my bike but I BELIEVE the way I drive (including coasting) saves me fuel, of course it goes a lot further than just coasting as others have stated, as I've said differing opinions but still all just opinions.

Oh you've been to track days. Why didn't you say.....anyway that changes nothing, your driving remains below standard. But you won't change and I won't care.

Good reply, must have took a lot of thought to come up with that LOL and of course you wont care, your the type of driver I watch out for and avoid like the plague!!

You have no idea what type of driver I am, you have told us one of your driving failings, I have some but haven't mentioned them.

Just common sense, most cars speeding are late for something. So leave early.

There is one light I can never beat so I go straight to neutral when approaching.

Complete redex cleaners are cheap I know at £3 but these are more intensive. Safer to use once every 2 or 3 years, though use cataclean before mot.

Neutral whilst rolling? That would be a bit naughty, and with modern engine management no benefit.

Luckily for me there definitely is a benefit to coasting as the last owner of my car was Fred Flintstone, no need to worry about modern engine management fueling, lol 

Just a lack of car control then, hence the naughty bit.

Not really, nothing hard about coasting!

No, not hard at all, neutral isn't soposed to be "hard" but quite simply you have no engine braking and have to change gear before accelerating if needed, there fore poor car control. I also suspect doing it saving you next to nothing anyway.

It'll waste fuel - when you're in neutral you need to burn fuel to keep the engine running. If you're coasting in gear, you don't.

The Weber DCOE carburettors on my car will pump fuel in while the engine is running, whether it's in gear or in neutral.  They'll pump in more fuel in gear because the rpm will be higher than idle.

Also, since someone mentioned engine braking, I'd hope that any car manufactured since cable and rod braking stopped being a thing has sufficient braking from the pedal to lock all four wheels from 70mph.
