Quick question re: revolutions per mile

I agree with Yaris Hilton, that you have been showing more distance than you've actually gone. What I do suggest is this......next time you go a long distance on a highway that has mileage markers, keep track of your odometer and what the highway markers shows. Very likely they will show different distances. The highway will show less miles than your odometer.

Another option, If you have a portable GPS, most will show your realtime MPH and you can use that instead of your speedometer. I have a Garmin Nuvi 255w and it shows my MPH on the main screen.

I do this check myself. I drive 10 highway miles ane compair that to the odometer. If the odometer showes 11 miles for every 10 miles driven than it is now 9% fast. If your speedometer showes 110 mph you are actually doing 100 mph.
