You can run 5W30 no problem.
I ran 5w20 Mobil 1 in my 4.6 2005 Ford Crown Vic for 300K miles in Miami Beach jungle heat. At one time my entire family had Panthers and we only used 5w20 M1. We did 5-7K miles OCI or 6 months. Probably could have gone longer but there is 24/7 gridlock in my neck of the woods.
I don't bother with 20weight oils down here in this sauna.

I do and have in 2 cars that call for 0w20 and 5w20. Been over 300k between the 2 vehicles so far so not to worry.
The 4.6 was originally specified for 5w-30...which is what I'd be using.
As far as brand, that will depend on your planned OCI as well as your driving habits.

I would (& do) use Castrol Magnatec, in 5W20 (me) or 5W30 (you)-it really does help with cold start noise, along with an XG2 or other quality silicone ADBV filter. My '03 is looking like three 7500 OCIs to one Ultra is going to be easily doable.
I'd run this down in that Tx heat.

Either 5w-20 or 5w-30 would work fine. My choice would be 5w-30. Run it in my Ranger which is spec's for 5w-20 and no change in mpg or anything.

When I had a 99 Mercury Grand Marquis and using 5W30 Motorcraft I always had to add a quart of oil between oil changes. Then Ford back spec'd it to 5w20 Motocrcraft Blend. I used zero oil between oil changes. Soon after changed my oil to 5w20 Mobil 1 AFE. Used zero oil between changes.
I have no idea why so many people here keep pushing HM oil on vehicles that do not need it and will probably never ever need it. I put between 200-300K miles on all my vehicles and never used HM oil.
The 4.6 Panthers were the best vehicles ever made. There will never be such a low maintenance vehicle [that road like dream] ever again.
Of coarse all that just IMHO.

I ran a Ford F150 with a 4.6 out to over 250k using mostly QSGB 5w30. The engine was still running great when I sold it
Well I'm definitely glad to hear about the reliability in the 4.6 V8 that's exactly why I chose a panther platform vehicle. It will be a Texas Highway cruiser for me as I do travel often for Dallas-Austin-Houston.
Think I will be going with a 5w-30 Castrol Synthetic oil w/ Wix filter.

Yeah I was looking at the latest year lowest mileage panther platform car I could afford and ended up with a 07 Mercury Grand Marquis with 89k, After owning a 05 Cadillac SRX that turned into a problem after problem money pit I now want a reliable hwy cruiser.

That should work just fine. Good choices all
