MPG

[Ldub]

I then remembered the adjustment I had to do with my Trooper and oversized tires, and sure enough--each mile marker I was only clocking 9/10 mile, so that improved my mileage. (though don't know if I am going faste or slower than speedometer reading...)

If your odo is registering less miles than actual, then your speedo is registering less than actual too.

If your margin of error is 10%, 60 mph registered = 66 mph actual.

Well, THAT would explain all the slow-*** people in the left lane!

thought is was the opposite; if it said 60 I was only doing 54...
