Fuel gauge: low fuel indicator

[Mittelklasse]

I got no bar at one time .
Battery was dead. I think that was the sign of the fuel pump not working, the motor couldn't even crank.

On topic: on my Yaris, the last bar starts blinking fast when there's about 12 litres (~3.2 gallons) of gas left.
I once drove for another 100 km (62 miles) and still had about 5 liters left in the tank.

However, I suggest refuelling as soon as possible, as you could potentially burn out your fuel pump driving extendedly with low fuel.
(Gasoline has a cooling effect on the fuel pump.)

400 MILES

I once got 380 miles on a tank, but that was a rarity.

I get over 500 miles on almost every tank. The official capacity of the tank is what, 11.1 gallons? However, the 'absolute' capacity (for lack of a better phrase) as demonstrated by CTScott's calculation (and my own 12.777 gallon fill up) is 12.8 gallons.

Are you guys going to empty?

The 12.777 gallon fill up = when I ran out of gas while pulling up to a pump to get gas. My usual fill up is probably between 12 and 12.5 gallons. I pay ettention to how many miles I'm getting from each bar on the current tank as well as the total miles so far on a current tank when deciding when to fill up.

Most are mine are in the 8-9 gallon range. Makes more sense now.

Also note nookandcrannycar fills the tank until he can see the gas.

What I would like to do is add more capacity to my gas tank. I have often toyed with the idea of getting a 20 gallon tank. You could go a long way or a long time without gassing up.

I wonder how hard it would be to drop the OEM tank and get an aftermarket tank. How would that effect the gas gauge?

Oops. I do know how to spell attention .

The fuel pump is actually submerged in gas. To run it dry means you would have to get every single drop of gas out of the tank first.
