Klassic - thanks for the info - I will try that today! Didn't know that option was there.

 

Exactly my point if that is correct. Leave it alone do the mileage calcs in your head and record less miles.

 

Glad to hear I'm not the only one with this issue. We have a radar stand setup at our govt. facility and in both my 2004 and 2005 it says I'm going 2-3 mph slower than what my actual speedo shows. I need to use my gps to see what it says, should be more accurate.

 

And when it comes around and your getting LESS MPG, dont worry, your putting less miles on your truck as well, there is always a sacrifice for a benifit.

So you either have...

Less miles on truck & MPG calculated wrong

Or

The right miles on truck & MPG calculated right
