Jeez, 13 mpg that must be awesome. I can put alot of blame on the remote start. I don't like to wear my coat when I drive, so it has to be warm during the winter. I actually get better mileage during the summer months I average about 9 mpg with no highway driving at all. I came from a lifted TJ so this is surprisingly an upgrade in the mileage department.
tinted, remote start, slightly debadged, HID's, lockpick camera, truxedo deuce, Volant, linex ,more to come, just have to convince wife!
