TDIwyse, that is excatly what my Garmin Ecoroute shows me. Also shows higher engine load with A/C on.

Over past 2+ years my average MPG has gone up in the winter months and down in the summer months, even though traffic is theoretically lighter in summer with the kids out of school.

It's the A/C. I'm sure of that.
