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.
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.
