Hey everyone, Im brand new to the forum and this is my first post. After taking my 96 Explorer to the desert riding dirt roads for a day. The roads werent bad, I never even needed 4 wheel drive, however, the conditions were extremely dusty. Since that day I have been getting 30-40 miles less per tank of gas. Im not very knowledgeable about engines so im wondering can dust in an engine take away from gas mileage? clog a fuel filter? fuel pump?
