I just had my ram in for its first oil change at 5k miles. Olm was at 50 percent but wanted to do the first one early. I asked the service writer what they use and she stated it was a synthetic blend. i asked if it was pennzoil and she called and confirmed it was. Does all ram/Chrysler dealers use pennzoil per a contract? I saw they had advertising for platinum also. I did appreciate the free oil changes through ram!
