So what do you guys recommend from these 2 oils?
I have a 14 Ram 5.7 and I am going to do my first oil change soon. I always run Royal Purple on all my other cars but this truck is still on the factory fill and the manual recommends Pennzoil or Shell since they meet the MS-6395 requirements and RP says they meet MS-6395T. So is that a problem?
I was thinking what you guys think between RP synthetic 5W20 or Pennzoil Ultra Platinum 5W20? I am going to run a OEM Mopar Filter on it still.
Thanks
