Narrative:

I had total fuel exhaustion after three hours fifteen minutes in flight. Aircraft burns 12.2 gph with 55 gallons total; 53 usable; for 4 hours 18 minutes of fuel. Flight computations showed max fuel burn would be 45 gallons for 3.7 hours of flight. I ran the plane 50 degrees rich of peak egt. Subsequently I have learned the egt gauge was out of calibration. I was burning nearly 15 gph. Lesson learned; get familiar with any new aircraft. Aircraft was landed without incident and upon landing called FSS and had them call the center with landing information.

Title: C182 pilot reported fuel exhaustion in flight when fuel was burned at a higher than normal rate due in part to an inaccurate EGT gauge.
