I think you guys should read this. Basically you want the lowest Xw number possible in order for the oil to warm up to it's proper viscosity. Higher viscosity oils do nothing to protect your engine. In fact, you're harming your engine by using an oil that is too thick to properly lubricate your 4.6l. The only time you should use a different oil is if you have a built dedicated track car that sees unnaturally high temperatures. Either 0w-20 or 5w-20 is the way to go.

Some of the information in the stated post is good, but some is incorrect as below..
"Remember that oil flow is the only thing that does the lubricating"
Wrong, you can have all the flow you want but without pressure the bearings will not have an oil film between the bearing and journals and the bearings will wear out pretty quick.
