Anahymbrid,

My light might have come on at 2 bars if I drove more. I still had 2 bars left on the display, but I filled up and never saw the light. Can you really fit another 1.8 gallons in after first click? I put in another .6 gallons, but then got timid as I did not want to overflow the tank. I still would like confirmation from somebody who has pushed the tank further on how much is the real capacity left over when the light comes on.
