The fuel gauge never changed! Just filled it up again at a local pump, and it took about 5 gallons. Really topped it off. Gauge is still at one dot below full. The gauge has seemed quite accurate over the past 6K miles.

Is it temperature related? This weekend is the first weekend where I've owned the car in actually hot weather, 95+ degrees.

Is the "stuck" gauge the same cause as the "won't-read-full" problem?

Looks like I'm in for my first Nissan 370Z service.
