I have a Honda Civic Hybrid 2008, with 150,000 miles. I live and drive in Miami, where the temperature is high, so I use AC a lot. I took 2 measures. On the first one, I used AC most of the time, but not always, and the consumption was 37.80 miles per gallon. On second one, I almost always used AC and the consumption was 32.44 mpg.
Is this normal?
