There is one more scenario I see on my morning commute. There is a long downhill area that I drive every day, it is not a steep hill so when I am driving, coasting is actually more efficient. If I leave it in gear the engine breaking combined with drag is too strong and I cannot maintain speed so I inevitably use more fuel preventing the engine breaking while at a relatively high RPM than idle. It should be noted that I drive a diesel that has more engine breaking power than most spark ignition engines, so some cars may not see this same effect.
Lol
What about when you’re not going downhill?
E.g. You accelerate to the speed limit, then see red light in the distance, no cars behind, and you just let off the brake or coast to the red light (assume perfectly even road surface)?
You may not be using any fuel when engine braking but you will slow down much sooner and will have to re-apply the throttle Whereas if you coast, you will be using idle fuel, but you will be able to reach the red light without touching the throttle
?
Is putting it in higher gear considered as coasting? When I’m going down a hill and I want to save gas I ussually put it in a higher gear and not touch the throttle. I ussually get good FC when I do that.

What costs the least fuel? Switching to a Tesla!

I prefer engine brake mostly to keep it “leashed” the car just gets no trotthle imput
Only an idiot would put a car in neutral when driving it. That’s a recipe for disaster, no matter how much fuel you’re allegedly saving.
Oh there will be more soon! I run methanol when its on boost! Its got an AEM water/meth kit in it!
its the same but engine braking consumes less braking pads duhhhhhhh!!!!! without watching the video a 10 year old boy knows it
