My first car, we couldn't keep the gas gauge working reliably, so I had to reckon the mileage from the odometer to keep track of whether it needed to be filled.

My first car, we couldn't keep the gas gauge working reliably, so I had to reckon the mileage from the odometer to keep track of whether it needed to be filled. At least it did have dual gas tanks, so in the worst case, you'd notice the engine was chugging and trying to die, and have to flip the switch to the other tank in time. Filling up both tanks kind of sucked, back when gas was $3.50-4.00/gallon.
