I just did the same and know for a fact they used Rotella T-6. I was informed by the Service Manager that they have a TSB telling them that is what they are supposed to use.I just got my first oil change as part of the Jeep wave program. I’m not sure they used the correct oil. The receipt lists part number 68001332PC. That is not listed on the sticky at the front. How can I confirm if this is the correct oil and if it isn’t prove it to the service manager?
