Someone posted a clip of a 2013 OM the other day. The required max oil change interval has been extended.
From the 2011 Patriot OM
Under no circumstances should oil change intervals
exceed 8,000 miles (13 000 km) or six months, whichever
comes first.

From the 2013 Patriot OM
Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
What changed to extend the max (read Warranty Coverage) OC interval by 2,000 miles/6 months??? The maintenance chart has also changed for 2013.
