I have about 8,000 miles on my daily driver Charger Scat Pack and will be doing my an oil change soon. I changed out the factory fill at about 4,000 miles and used the Pennzoil SRT Ultra Platinum 0w-40 oil with a SRT(Viper) oil filter. For this change I want to try Mobil 1 0w-40 or Castrol Edge 0w-40. Filter will be Fram Ultra. Any thoughts on which oil the Hemi will like better?
