When I was a young boy, when my Dad got a different car one of the first thing we did was to put mudflaps on it.
This cut down on the rocks and sand thrown up to the side of the car.(Minnesota the land of ice & snow)
Now I do the same thing with all my cars.
But putting mudflaps on my 2013 Volt would add to much drag and lower my mileage????????????
Would like to know everyone opinion who has added mudflaps and did it change the mileage?
