So much great info. Thank you all. I will switch it to a full synthetic in 5w20 and stick with the 5,000. Time for a trip to Walmart.
Severe service?

Im in Michigan,those who asked.
At only 5,000 miles (not hard to do with this Venerable 4.6 liter engine) -
I'd skip synthetic and just use what ever is cheap or rebate for 5,000 miles.
No synthetic needed at all.

Where did you find a 2004 Panther body with only 24,000 miles on it?!?!!?!?

Seriously, seems a lot of thin hate lately with absolutely no proof of any issues with it.
And the argument that "it was originally spec'ed for 5w-30" is not a valid argument, maybe engineers found that 5w-20 is a better oil for it (since 5w-20 was not around in abundance when the 4.6 modular was designed). And yes, CAFE played a part in it, but not all. I am still looking for the millions of 2v modular motors with engine failure due to 5w-20 being used.
This engine and engine family gets 5W20 on cheapo bulk in fleet use and the idle time in the desert is a lot more than the OP is stating for his vehicle. Then to top it off they are then immediately thrown into WOT after hours of idle.
I worked at a prison for a little over a year and we had a few crown Vic's that were used to patrol the perimeter of the complex, 24 hours a day they idled around, never exceeding 5 mph and never shut off not even during refueling, I'm unsure what oil they used but in my time there they only put around 600 miles on them
I worked at a prison for almost 26 years until I retired and our perimeter vehicles used recycled oil and they ran slowly or idled 24/7 except when they were taken off line for maintenance or repairs and I don't remember any of the vehicles ever having engine trouble. We did run some crown vics but mostly full size pickup trucks. I don't know what viscosity they ran though.
