Decrease MPG in 2011 Camry

[Neuteredbynature]

Took the car to the dealership to get checked. I guess because I wasn't dressed like a mechanic they chose to ignore everything I told them. When I finally got my car back they told me someone would explain what was wrong--there was no one. A mechanic who didn't work on my car gave me my car back; he had no clue what was going on with my car. The notes they wrote were common sense "AC on can cause fuel consumption, traffic, or difference from winter to summer fuel". Yeah because after 3years I wouldn't know the difference. Silly me. They only checked the electrical aspect of the car and they said it was fine. They didn't check anything else. I will continue to monitor my car. Thank you all for your helpful tips. You guys were a bigger help than the Toyota people.
