Pennzoil ultra is a better oil only because it will last up to 15000+ miles in service.
Ultra is equal to M1 EP. They are the same tier.
I'm a pennzoil guy however I buy whatever is on sale these days since in service I doubt there is much,if any difference between oils of the same tier.
I use Mobil when I can find it on sale,and will use whatever is cost effective for 10000+ mile intervals.
I'm not one o those guys who buys top tier oils and filters and changes them at 5000 miles. It's not cost effective nor is it smart. I run my oils out to an extended interval that I base on looking at other hemi's used oil analysis using the same products.
You can't go wrong with either of your choices. Buy whichever is cheaper and run em the 10000 miles they advertise.
