When to refuel when your gas tank is half full?

On the flip side, the less fuel you’re carrying, the better your gas mileage (at the expense of traction). Half full seems way over the top. I normally refuel somewhere between 1/4 and shortly after the low-fuel warning coming on. If I were out in the back of beyond I would always make sure I had plenty of fuel to reach the next filling station.

Can a car run with an empty gas tank?

You probably shouldn’t continually try to crank a car with an empty gas tank, but I doubt a second or two of fuel-free running would overheat a pump. Water can get into your fuel tank in two ways: mixed into the pumped gas when filling, or as humid air being pulled in as fuel is being pulled out and used.

What makes a car stall when the gas tank is half full?

The car stalls out when the fuel tank becomes half empty and yes, gets worse as more fuel is consumed. Slowing down doesn’t seem to cause a problem but coming to a hard stoop at the bottom of a hill will make it stall after braking.

What happens if you empty your gas tank twice?

For the latter, as cbeleites noted, emptying a tank halfway twice pulls in exactly as much air as emptying a tank completely once, so again you’ll get the same amount of water pulled in no matter how you split that up into fillings. As freeman noted, OEM fuel tanks these days are plastic, not metal, so corrosion isn’t going to be an issue.
