17Is it true that cruising in gear in your car does not consume fuel?

My car’s fuel computer says I am consuming 0.0 litres per kilometer when I am cruising in gear with my feet off the accellerator (gas) pedal (e.g. going downhill, coming up to a junction, or roundabout etc.) Is this true? How is it done? The engine is still running. I can hear it! Is the computer wrong?
If it makes any difference, the car is powered by a diesiel (gas oil) engine.

If the engine is running then it is consuming fuel. Nowhere near as much as when your floored but an egine burns fuel to run period.
yes, if the engine is running its using fuel, u happen to have lots of momentum at those times so the computer calculates it all wrong… did you notice that when you hit the gas again to get back up to speed the milage goes way way down then balances out
the computer calculates the qty of gas by making an average of ur speed and miles
as long as the engine is running…it still consumes gas…
it is true, fuel is only injected into the engine when your foot is on the gas….
As long as the engine is running, the car is consuming fuel. Those trip computers are only an estimate and not an exact measurement. When going down hill with no input to the accelerator, you will be burning very little fuel when compared with your speed at that moment. Probably not enough for the computer to show a measurable litres/km so it displays a 0.
The computer is wrong. You’re still using gas.
It all depends upon what type of car you have. If you have something like a hybrid, then you might not be consuming any fuel when cruising. If you do not have a hybrid, then yes, you are still consuming gasoline. If the engine is running, you can tell by the RPMs being performed, you are consuming fuel.
Think about it! Does the engine not consume fuel if it is idling. It’s called common sense.
The computer can not display a negative number
if your coasting at a rate that is faster than what the engine
should be producing the computer doesn’t know what to do and displays zero….
Lets say your costing at 40mph but you have your foot off the pedal.
the resulting mpg is less than 1/10mpg so the computer shows 0
Depends on the car. Some cars have fuel cut off when coasting. Some cars ,Dodge Caravan, use more fuel even though the engine kind of freewheels. It is to keep the catalytic converter hot. you can thank your friends at the EPA for poor auto economy. But the cars don’t stink as bad as they used to.
as long as your engine is running you are consuming fuel only less very much less than when your foot is on the accelerator.
I can’t imagine if it is in gear it would not use gas, but I have been told that if a car is in neutral it isn’t using gas although that doesn’t seem possible either.
