Ok... spent too much time combing threads here. I drive a RAM 1500 with a Pentastar 3.6 and most of my driving is mixed, Hwy/City with mostly good cycle times. The OLM will go to about 10,000 miles if I'd let it. I'd like to stick with a Chrysler MS-6395 spec'd oil until I'm out of warranty. My first change I used Penzoil Ultra but thinking PYB @ 7500 miles would probably do just as good. Any other oils that perform well in the Pentastar?
