If it isn't the Duratec, stick with the recommended amount.
I have been running 5 qts for a long time now in my zetec, I do however have a very slow leak in the oil pan seal or the rear main seal. I used the valvoline high milage for awhile and it stopped then it came back worse, I put coventional oil back in and it seems as it was before
also I thought part of the 5w-20 change was the fact that Ford could claim beter fuel milage on the highway. since as you know they have to sell a certain number of "clean" cars from an emmisions stand point to be able to sell all those SUVs and trucks that are not as "clean"
