Better gas mileage in the summer is related to gasoline oxygenation for the most part. But the difference is usually about 10%… You have about a 25% decrease, and that seems high. What maintenance does the car get? How often do you change filters and oil? I assume that you are driving on the same roads with the same amount of traffic.
