Next time keep your car in gear when cruising, you will use no gas this way or less(up to a certain rpm)

No, the real moral of the story is that you should always know what your average consumption is, day in, day out and '0' your trip oddometer when you fill up each time - that way you will have a much better idea of how much further you can reasonably expect to be able to go. Also you need to fill your tank to the same point each and every time when calculating your average consumption - whether that is till the pump shuts off automatically or filling it to the top on a very slow fill ( I have found that the difference between the two represents about 5 ltrs (just over a gal. US) which represents about 50kms (30 miles)). The tank is 50 ltrs I believe. So now you have all the numbers you need to be able to calculate how far you can go at any point in your trip before you will run out of gas.

Wow. You have GOT to be an engineer. How about just fill the tank before hitting the highway?

Haha, this. I hate having less than 1/2 a tank anyways. I don't mind stopping for gas that often.

This is my method (Since I do long distance on highway quite often):
Fill up gas tank not too far from the highway
Set Trip to 0
Drive till the other destination's nearest gas station
Record the distance traveled, refill and check how much I used up

I tried a couple times, and the average is 8.84litre/100km (27.54mpg) with 0.49 sample standard deviation on the highway
Never did local though, which I should

haha, yes this has happened to us all. When there are about 4-5 bars left, those bars drop really really fast. I know and have heard of owners driving up to 30-40km, on zero bars, but I don't like taking those risks. I too now use the zero and average approach. I know when it hits around 370klicks, I fill her up stat.

Cruising in neutral uses gas since your car is idling.
Cruising in gear when not stepping on the gas, actually uses no gas.
In this case, your engine speed is driven by the wheels.

When you're not applying throttle, the car doesn't inject any fuel?

Nevermind, just looked it up. Many cars cut fuel on deceleration. The trick is to understand how to balance the saved fuel while in gear vs the deceleration cause by the engine braking. I only do it at night, since I'm not crazy about neutral coasting with other cars around, but my best results have come from neutral coasting.
