Welcome!
Congrats on your new ride!
Most people run an extra half quart to a quart of oil in their Duratec. There can be an oil starvation issue on sweeping right hand turns and this helps to prevent that.
Read up on the individual forums (stickies at the top) and you will learn a great deal about your new tour. Also, check out the "Main Site" (top of page), there you will find all sorts of information, where to buy parts, aftermarket parts, how-to's, etc.
Enjoy the site and your Contour.
