What's the absolute maximum range of your Duster?

Cruiser, I vaguely remember that the manufacturers would put a gas tank on a car that had the capacity of fuel to give a mileage range between 225-250 minimum. The range would be larger for the more fuel efficient engines when compared to the high performance ones.

During the gas crunch we would alter our driving habits to squeeze better gas mileage. There were an abundance of aftermarket vacuum gauges that had a color efficiency indicating face. Using such a gauge would allow a driver to cruise with a light gas pedal. There were other practices that were discussed in previous threads. One particular set of practices was called “hyper miling”.
