FWIW, I now use Mobil 1. After 15,000 miles ( you read right ) the oil was still dark tan in color and semi-translucent. Not see-thru, but still allowed sunlight to pass.
After 3 changes, ( @5,000 miles, dealer comp. ) ( @8,500 miles, switch to Mobil 1 ) ( @20,000 miles Mobil 1 ) my hex drain plug became "round".
Just recently, at 35,000 miles, I did another oil change and had to leave the hex drain plug in, and just unscrew the entire filter. It was not any messier, and actually, the times it worked, I didn't find the hex drain plug all that helpful. So yes, I changed the big O-ring, but had to leave the small one in. Hey, no leaks, and that's all that matters. If the small ring ever does leak ( doubtful for at least 5 years ) then I hope I can take a dremel and cut the hex into a slot for a standard screwdriver.
I was not able to find a "cap" or socket type filter wrench that fit at any auto store, and I was not about to get one from a dealer. I got something that looked like giant pliars or "channel locks" shaped for a round oil filter. Worked great. Very easy to use. Yes it is steel "teeth" on plastic, which will leave small marks, but who cares!? No one will know but you and perhaps a mechanic. The ease of use is worth it.
This is not the exact one, but you get the idea. One size fits (nearly) all.

-Anyone know the exact diameter for the oil filter "cap" that holds the filter & screws into the block? Is there a special tool since it is made of hard plastic, so as not to round it or scar it?
-Finally, is the smaller hex drain plug a true MM size, or a poorly machined SAE? Anyone know what size for sure? I seem to recall 6mm, but it was not a snug fit?
Thanks for the info on the oil as well. Since the '02 Stang also uses 5w-20 I go thru it a bit quicker than I'd like.
And yes after 5K of primarily fwy driving in LA, the oil was black! Back up to 29.6 mpg so it beats my '05 Exploder.
