I drive the same commute each week (usually) and fill up each Friday.
They are mostly highway miles with city traffic in the morning 3 days a week.
My experiment consisted of using traction control on one week and off the next and just compared mileage.
Its not the most precise measurement as I have no charts or proof, but try it and you'll probably get results.
You just have to remember to turn it off each time you start up the car.

I haven't really noticed much of a handling issue.
