Reliability of the engine itself is great, you more have to worry about that Chrysler transmission. If it is a 2014 or 2015 those might be better, but time will tell.
Ram truck transmissions have been very reliable for many years, including the 545RFE used in 1500s back to ~2003 or so until it was replaced by the ZF 8HP. The problems tend to be with the 42RE in some Jeeps (and its usually caused by a $2.00 part- not an excuse though). And then there is the front-drive junk- never get anything with a 41TE, and I've even been suspicious of the 61TE although it does as well in minivans as Toyota's Aisin and better than Honda's did for many years. Hauling a minivan with a small transaxle is a tall order.
For the OP- Pennzoil has been factory fill since 2011. Before that it was Mobil products for many years. Base v6 and V8s use conventional (or blends in the case of 5w20), the SRT engines use synthetic (Mobil 1 0w40 through 2011, Pennzoil Euro 5w40 in 2011, Pennzoil Ultra 0w40 since 2012).
Is the factory fill 5W-20 on the new Hemi's a synthetic blend or did you mean blend of weights?
I am considering using 5 quarts of PYB and 2 quarts of Redline 5W-20 to make a pseudo-syn as I only drive about 6k miles per year and will change at that time frame. I have to buy 2 gallon jugs currently and the other 3 quarts will just sit for a year in my extremely hot garage, which I would prefer to not do. I could of course buy the extra 2 quarts of PYB but the cost is not a whole lot more and the Redline might help squeeze out a tad more MPG and has high moly content like the PYB.
