What's a good average for the miles per kw/hr

[jlv]

The miles per kw/hr goes between 4.5 and 4.6 per the gage on the car. Does anyone even use this reading and Is this something that can truly reflect your efficiency?

Just remember to reset it once in a while; at least once per season. That way you can get a real feel for your efficiency in the winter months vs. the summer, etc.

If you have an SV or SL, there are actually two such gauges: one on the dash and one on the center display ("status"). I reset the center display each season and the one on the dash weekly.
