well do to others "beta testing" it's been proven that a 2010-2013 Chrysler 2.4 (Chrysler 200, Dodge Avenger, Jeep Patriot) will go 35K on the original oil.... just don't go 38-40, it'll fail laugh2 We've seen two go the above listed miles.... I can't comprehend HOW anyone can be so far in left field as to NOT change the oil. These cars even have "CHANGE ENGINE OIL" messages that come up in the cluster. Both claims were denied.

I changed oil on a 2015 2500 Ram with a diesel last week with over 14K on it. Oil % minder was at 2%. It would be interesting to see how that one survives at it's current pace.

Our Pacific with the 3.5 used a qt of oil every 3k until it had 140K on it. Now with 198K it will go 4K + and not use a drop.
2500 w/t Cummins 5-7K it gets changed. 168K on that one.
96 4.0 Cherokee. lots of short trips and slow desert driving. every 3K 164K on that one. We need a new car!
