So here's my ride: 2006 scion xb with 5speed. Since I started trying to increase mileage I've inflated to 45psi, put in a K&N filter, removed air box snorkel, and most important of all I have been using the scan gauge. Also more for aethetics I purchased alloy wheels for summer, but picked out the lightest ones I could afford which are about 5lbs lighter than stock steelies. I live in Alaska and in the winter it can be a challenge to get good mileage as I'm sure it is in any cold climate. This winter especially we've had some weeks of -10 to -20 below zero weather. I run studded tires since we get allot of ice on the roads. I think ICEBOX prettly much sums up the aerodynamic look of my car, although they actually do well, infact the drag coefficient is lower than a new VW Beetle. Can't say the same about frontal area though. Most of the year I drive 90-100% city. During the short Alaskan Summer I tent to get a mix of hwy and city. I bought this car because it's very practical and different. Gets great mileage, cheap price, loaded standard features like all pwr accessories, traction control, stability assist, and most important it can haul my biggest RC planes like my 33% scale aerobatic plane. It has more carrying capability than my previous s-10 pickup and gets more than twice the mileage! I've averaged close to 35mpg, but just recently have I actually tried to get more. Best tank this winter so far is 46mpg, that's with cold weather and studded tires, 100% city. Can't wait till summer!
