Upgrading to larger wheels will kill your mileage because of the increased unsprung weight (more metal & more rubber) and the increased rolling resistance (wider footprint). There is a built in volume to the fuel tank to allow for expansion. If you fill-up using your slow/rock'em/sock'em method and fill until you see it at the top, you have not left enough room for heat related fuel expansion. Now do this on a HOT day and then let it sit in the sun you are asking for trouble. Liquids are not compressable at all. That is why any time you see a bottle of liquid there is always a space for expansion. Pumping gasoline stored underground that is cool into your vehicle your way does not leave any room to expand. It may take a while before something in the system weakens from the repeated expansion stressors but someday something will give somewhere--like a gasket or a weld seam, maybe split the fuel line or rupture the fuel filter. Can't say because I am not an engineer but I've taken several physics courses and I have slept at numerous Holiday Inn Express motels! As far as the manual calculation, it's the average of many fillups that will give you a truer fiqure. Years back they didn't just take one person's temperature and call that normal...they did thousands and at different times of the day to come up with 98.6. The recommended procedure is to fill at same station, same pump, (if you are super anal--same time of day) allow 3 click-offs and stop. Record your volume and miles, reset and take off. After doing this for several tankfuls and you will begin to see a more accurate average value develop. Want take it a step further? Also record driving conitions with each fillup...all city, mixed and mostly highway. If you group your averages under these headings you can then see the 3 different trends emerge. Cheers.

Hi Everyone, My wife has an '09 Edge Ltd and she found these same spots on her liftgate and other areas. The service manager and the dealer himself looked at it and said that it was not rust and that it came from parking under something! Well my wife doesn't park under anything except trees and the garage roof! But, her brother is an engineer for Ford and here is the story... Back in 2001 some higher up yuckity yuck thought that this particular brake pad was the best pad ever and ordered that this pad be used on all vehicles when it was possible. Well, the brake dust is the cause of these rusty looking spots. Why is it not happening on all vehicles?...when it was possible and the fact that this guy has since been canned. The dealers all know about it but no one wants to be the guy that starts a brake pad replacement under warranty avalanch. Since it is not safety related it will not shoiw as a recall. I am not sure if a tech bulletin exists, probably not. Cheers
