My service guy at the dealership here is old school and doesn't believe it. He insists I have to change at 3000 miles claiming there has been no major advances in oil or engine design. I think he's kind of an idiot, but don't really know what to tell him.

Can anyone tell my why Chrysler has extended the OCI to this long?

Thanks for any info!


Reasons for longer OCI
1. Improved engine technology
2. Improved oil chemistry
3. Environmental considerations

I would recommend the manufacture recommendation but I would support it with a UOA.

Canned answer. You have a lot to learn.

3,000 miles is overkill.

8,000 miles is probably about right with GOOD oil.

However, many here on BITOG don't necessarily go the full interval on the factory fill or second fill of oil. Some here would do the first two changes after the 3-4 thousand miles each.

Update, the wifes pentastar is at well over 4,000 miles and no change oil indicator yet. This is after much highway driving. It is definately using some type of formula, not set intervals.
