At 60 mph (indicated by speedo) I am actually going 64-65 mph. Pretty big error. Anyone else have this problem? Tires are stock size. All I can think of is someone at some point put a different speedo gear in or the gauge itself has a poor calibration.
The upside is that I have been getting better gas mileage than I thought. Today I filled up, went an indicated 237.3 miles on 7.23 gallons. Multiplying the mileage by 1.075 to correct it gives me 255.1 miles. Divide that by the gallons and I got 35.3 mpg. Not bad for still having bad rear wheel bearings.
