Tips: reducing fuel consumption

[Christophe]

Zac, I hope bobone does not frequent the forum because if she sees that you are passing the big dog before her ... ouch ouch ouch

The bad languages

Zac put the big dog before bobonne because the big dog must be heavier than the bobonne in question.

Is not it Zac that it is a compliment for your blanket?

[zac]

Should we buy a big dog then?

[/ nina mode off]

you do not buy it you must adopt it and after you drag it everywhere because when you're not there it's all sad

Ps: for conso better pantone than a big dog

I didn't see that on my car, Christophe. But for the moment I am not "full": I have just redone a consumption at 6,4 l / 100 Not bad for a liner!

# Use the inertia of your vehicle (disengage) rather than the engine brake! So you can win 10 at 20% in town by anticipating well. But beware of your safety that comes first!

To qualify ...
If the slope or the slowdown zone allows it, the use of the engine brake on fuel oil allows less consumption than a period of "freewheeling", because in engine braking, the consumption is zero, which is not the case when you disengage.

Whatever!
That makes 10 years and more of 200000km that I use freewheel in descent straight line.
I tried during a period to ride like everyone else because I was told that it was useless and I clearly saw my cons that increased. I speak by experience and not with what can be read on books or learn to courses in mechanics.
By cons it would certainly not be as effective on other types of vehicles.
I would add that I have never changed the brake pads and that freewheeling must apply only under certain conditions and with a little experience.

hello, I agree for laz freewheel slope, I tested for a lot of km, but I always wondered if it does not eat my clutch even if I treat it like a baby, it is new and I wants to keep it.

4L 4,5L 100 for a twingo, it's really good! I thought that twingo was famous for consuming a little much compared to its small size. You use it on what type of trip, and is it changed? (except the rear seat lol)

Hello,

Freewheeling is questionable
first see what engine generation, on the old engines
even multi-point injection, the injection remains idle even decelleration, and idle consumption is rather disastrous on a gasoline engine (try to let idle a gasoline engine one hour and measure its consumption!
If I understand correctly you talk about engine freewheel stopped?
In the latest carburettor engines there is a small electric valve that cuts the fuel, (to avoid auto-ignition) it would be more sensible and safe to cut the fuel downhill.

For more recent vehicles (not all) in a downhill engine brake injection is completely cut so freewheel or not it does not change much in these engines. (just more speed)

Now in America most of the cars have an automatic transmition and put the transmission to the neutral in a descent is not recommended even to tow a car with an automatic transmition over a long distance there is risk of damage to the transmission.

For those who use this method according to the sort of mountain bike or long winding descent, there are risks for driving you must be sure to have brakes that will withstand the heat.

Hello
Freewheeling is a method of driving that remains attached to many parameters.
The first, the driver whose vigilance must be increased at this time, no question that it becomes a routine.
The vehicle, rather older generation that does not have a fuel cut engine brake.
Visibility and traffic (not too busy, see no charge at all).
Terrain, slope less than 3% or if more than short distance with recovery after.
But also as Christophe said in anticipation of a stop or a fire, an entry in built-up areas.
Engine stopped no, too risky.
but it works, the maintenance of a conso 5L / 100 on short courses enough to convince me.
Winter with the cold it becomes more delicate.

Totally agree with what delnoram has just said. For André, obviously I do not cut the engine because otherwise I would have more power steering and more brakes.
For antoinet111, there I remain perplexed; I was actually told that the clutch could patir:
When I say freewheeling it's at a standstill of course, but when I go back to speed it's at that moment that the clutch might be suffering.
Mine did 140000km but it is a utility vehicle so that is under load at this level.
