I have the same engine and I am switching to Mobil 1 on the next change. Again....it comes down to availability for me.

Nope. Just the vanilla Mobil 1.
 
I should also say that I could easily run conventional with my oil change interval. I choose to use synthetic, I buy the jugs at wally, because the price is so cheap and to me the price difference is negligible.
 
I think it depends on the interval you are going for. Maybe wemay can chime in. I follow a shorter interval because of how far and how I drive. I also have fuel dilution from the GDI. I follow the severe oil change schedule on my car.
 
I have a short-ish drive of 10 miles each way. No true highway for me. I have a stretch of road that is a tad over 6 miles that is flat, straight, 65mph, and no stop signs or lights. I honestly don't know if my oil get up to temp or not? I doubt it.

I am currently using PP. I am doing an oil change this weekend. I went in to get my usual jug and my local Wally was out of the Pennzoil. I went to the next closest Wally and the same thing happened. I just purchased the Mobil 1 instead. It was on the shelf at both stores. Seems to be the story for me around here. Mobil is everywhere. You can find it at any Wally, Sam's Club, O'Reilly, NAPA, AZ, AAP, and even Pep Boys. I will take convenience, good price, and a high quality product every time. Mobil 1 it is.
 
If most synthetics are hydrocracked petroleum based oils. Whats the difference between hydrocracked Syn and dino? Are they not the same?

No, not exactly the same but the gap between conventional and group III has closed quite a bit since SN. Group III is altered to create similar sized molecules and flows easier during colder temperatures as well as supposedly holding up better under heat and longevity which means less deposits for extended OCI runs as well as lower volatility. I choose to run group III over conventional for better flow more than anything else but it wouldn't bother me one bit to stick Pennzoil Conventional in my Ram 3.6L. My truck recommends 5w-20 (go figure), Quaker State Ultimate Durability in the 20w's has a heavy dose of the friction modifier Moly, which in my opinion can offset any lubrication difference between 20 and 30w oil, but it may not really matter in the real world. 30w Quaker State Ultimate Durability has the standard amount in it.
