Now I know some guys on here are gonna bash me cause I drive a dodge but my truck has been good to me. I haven't had the tranny problems others with dodges have but I don't know if its the oxygenated gas or what but lately my gas mileage has sucked. I usually get about 155 to 165 miles to a have tank which comes out to be about 12 mpg but this last tank I got about 135. I haven't changed my driving style. I don't put my foot to the wick I just drive normal. I just wnated to know if anybody experienced this in the winter.
