Don,

I don't have that fancy VMSpc stuff. I have to do it the old fashion
way on each fill up, dividing miles by gallons with pencil or
calculator...... From what I read, I believe that you, Leroy and
others really like it, and it seems fairly accurate based on the posts
I have read.

Just out of curiosity, what has been your experience double-checking
the VMSpc box on mileage? I know my Jeep GC read-out on mpg isn't
even close. It's always waaaay optimistic by 3+mpg.

Thanks,

commonly West-to-East is better than East-to-West, because of
prevailing winds, but also due to wind anomalies and of course
gradient direction. A good head wind can knock a full mpg off, as a
tail wind can add an mpg, for a difference of 2.
