Earl is earl
I've used 'em all in my 3.6L, all brands, all weights, conventional, semi-synthetic, synthetic - latest OIC was 4 quarts of 5W-20 Castrol Edge w/ Titanium I found on clearance for $4 (it's got TITANIUM!!) and topped off with some Castrol GTX Syn-blend 5W-30 - and it's all worked great. No problems, no issues, nothing...and that's while hitting the redline on the tach multiple times a day, every day.
I'm gonna let you in on little secret: it don't make no damned difference what oil you use as long as you use oil and keep it changed. And I don't mean every 3K miles, that's a BS OIC. Any conventional oil will do 5K easy, and in the Pentastars, they'll do 8K (we have an oil cooler, hooray!!).
If you are going to run a synthetic, run it 7-10K miles to get your money's worth out of it. Or don't, I've changed many a synthetic oils at 3K just for peace of mind...did I get my peace of mind, yes. Did I hurt anything, hell no. Did I spend money on expensive oil that should have been spend elsewhere instead, most likely. No harm, no foul. It's your money, spend it however you please.
The main thing to remember is when in doubt, get a UOA...they will help paint a picture of what's going on with the engine and with the oil being run in it. And for christ's sake, join up on the BobIsTheOilGuy forum and do some reading. You'll get all the info you can handle, and then some.
But I digest...what was the question? Oh yeah, favorite beers...mine is Blue Moon! I'm on my 4th one now, working toward #5...it's got brain-enlarging goodness at the bottom, so be sure to shake it up!
Nuke, OUT!!
