A quick trip to the salvage yard and that cap can be replaced by a 5W-30 cap, or better yet, a 10W-30 cap.
Do you pay any attention at all here or what?
Look at FX's myriad of used oil analysis and tell me if it's going to get any better than that.
Real data,not your methane infused opinion.

Totally ignore this bovine scatology and use what Ford specified for the engine. 5W-20 will have the engine FAR outlast the chassis in which it is installed. It depends it you want to extend your OCIs or not. If 7,500 is the maximum you will go on an oil change, I would recommend Mobil Super 5000 and a MC FL-820s for an oil filter--very reasonable cost and runs well in these engines. If you are going to extend to say 15K or so, I recommend Mobil 1 (5W-20 or 0W-20) and a Fram Ultra XG2 filter.
If you want to see (in general) how these two oils perform in a 5.4L (and also Pennzoil Ultra); have a look
here .
ha.
Beat me to it.
