Back when I was a young 'un, I drove an old beater with an
unreliable gas gauge. I got in the habit of setting the trip
odometer every time I filled up and noting the miles I'd used on
that tankful. I knew when I'd put about 250 miles on, it was
getting close to time to fill the tank. It's now a habit. I never
look at the gas gauge, I check my trip odometer.

The gas guage causes me to look at the trip odometer. That decides
if It's time to get gas. The trip odometer is a way more accurate
indicator of how much gas is in the tank.

Unless you left the vehicle idle, or it sprung a leak, or someone used
a "mexican credit card", or your brakes started to drag, or you pulled
a heavy load or had heand - all of which will cause the vehicle to run
out of gas sooner than the odo would indicate.

I don't do the first few thing, and if I'm driving with unusual loads, I'm smart
enough to compensate. I'm not trying to use every last drop in the tank either.
The fact is that in my experience, gfas gauges are very inaccurate and
non-linear.
