Yup. My 98 Civic is the same. I've been driving this car every day for ten years. I have come to understand the gauge distortion this way: the low-fuel light comes on at 9.5-10.0 gallons burned, though the tank is 11.9. I have run it close to 11 gallons burned, all the while looking at the needle below "E" and the fuel light on and pumping problems developing (I don't recommend this experiment). So the needle will be on "E" when there are still about 2 gallons in the tank, while it will show over "F" without filling past the first click of the station pump.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
