Markuss,

At 100,000 miles you should check the O2 sensors (actually you should probably just change them out). The TPS or throttle position sensor may also be off a bit and the computor will richen the fuel across the board. Also the Mass air sensor (if it has one) may be dirty and getting a false reading.

Did you check the odometer for accuracy? Some are off.

Best of luck getting the most mpg -
