Actually, checking your fuel economy on a regular basis is about the best way to monitor your car's performance. Once you establish a "baseline", if MPG changes in a way that's not "normal", it's a sign that something may be wrong. I do MPG every time I fill up, on all my cars, even the ones without flight computers.
