Sorry if this has been discussed before, but I'm curious about the accuracy of the mpg readout. I just today finished a drive on the first tank of our new CRV. The trip was about 170 miles downhill to the coast and the readout was an amazing 37.6 mpg. I'm having some trouble believing that's for real. My Hyundai Elantra GT regularly reads about 2 mpg high. Is the CRV equally optimistic? Of course I'll know when I fill up, but figured someone already had a good idea about the general accuracy. Thanks.
