I personally have been using Pennzoil mostly for the last couple years based on UOA I have seen. I do indeed like Valvoline as it seems to do well with resisting blow by and oil usage. I have been using 5w-20 pup on this oil change and my Ram has made 3 qts disappear in 7K. I have 5w-30 pup and RP filter ready when I get home from vacation. I am hoping the oil disappearing can attributed to the thin 5w-20. I used to use 0W-20 regularly when I ran Valvoline Syn. If you want to go 10k get a premium filter and a premium oil.
