Increasing mileage efficiency. How do you do this?

Philipp_Bach

Regarding to using fuel additives and cleaners - this post is a good way to know what manufacturers proposed, what efficiency guaranteed or not guaranteed.
I think even if the car relatively new, e.g. 1-3 years, non-frequent using of fuel system cleaners can help to get rid of some potential malfunctions in the future.

If a light in front of me looks like it has been on green for a while, I will ease off the gas because it's bound to change soon.

Well yes the driver that got through the light would save fuel but if your a good driver you can 'gauge' when lights will change and adjust your driving to suit. If I'm approaching traffic lights and I can see (cant always see that far ahead of course) that they're on green I still carry on at same speed no flooring it to get through and if they stay green no problem, IF I see them change to red I immediately dip the clutch (not technically driving standard I know) and coast to a stop.

This is what I do. One thing I remember from my engineering degree is that diesel engines are most efficient when idle.

Also it's very satisfying if you've read the road ahead so well that the lights change whilst you're still rolling, and the idiot who raced past you to only then have to slam brakes to stop has to do a standing start as you pass them.

This thread really emphasis that a statutory 10 yearly retest is maybe not such a bad idea (unfortunately)

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!

Driving instructors are divided on it.  One of my instructors actively encouraged me to do it, but told me not to do it in a test and  another said it was dangerous as you don't have full control of the car, plus it isn't good for the clutch.
