    I drive a 2010 prius and get good mpg summer (50-51) winter (46-49). I am thinking of buying Weatherteck side window Deflectors and I would like to know if this would affect mileage. Thank you.

    Depends where you are and where you use the car. If you mainly use it in a city then I'd say go for the window deflectors as I appreciate the benefits they give regarding draught free fresh air. I can't imagine they affect economy that much and probably cost more to buy than the increased fuel consumption.

    Just go for it. I believe the forum shop offers them for sale, but if not, you can find them on ebay.
