Nope...

Engine Oil
We recommend you use API Certified SAE 5W-20 Engine Oil, meeting the requirements of Chrysler Material Standard MS-6395. Refer to your engine oil filler cap for correct SAE grade.

GTX 5W-20 meets the spec...

Synthetic Engine Oils
You may use synthetic engine oils provided the recommended oil quality requirements are met, and the recommended maintenance intervals for oil and filter changes are followed.

No "Will, Must, Shall or Required"...

 

What changed to extend the max (read Warranty Coverage) OC interval by 2,000 miles/6 months???

I seriously doubt Chrysler changed anything on this motor at all. I think after Dixie came in with a blown engine at 100,000 miles, they figured it to be a good time to increase the oil change interval :doh:

I wonder if they can reprogram my 2011 oil minder to match the 2013

The OLM programing may not have been altered. Time and miles are not part of the formula for the OLM. It has to do with temp, idle time, RPM's, and other factors related to actual use.

 

I would never run oil for 10k miles... I change regular oil every 3k and synthetic every 5...

 

In a healthy engine you are wasting money dumping modern oils at such short intervals unless you are doing so to stay wiithin warranty requirements.

 

Lots of car mfg's are starting to extend out to 7500-10,000 and a year. Modern oils can do it in a healthy engine. Also, I am going to assume here that with the vehicle being equipped with an OLM car mfg's are figuring that will trip and result in the oil being changed sooner in vehicles that are used harder.

I would like to see Chrysler(Jeep) back spec the older Patriots to a year and 10K. I only do about 7-8K a year tops now and I run synthetic. A year and 10K would be good for me.

 

I will have my first oil change at 1 year mark, Im at 2450 miles today, next month on the 14th will be 1 year.

 

Ive been driving almost a year and my oil change indicator hasn't come on...

1 year mark is February, 14 2013

Im at 2450 right now

 

I'm at 3300 miles at 8 months and going in for my first oil change this week.
