I believe this is the official FCA specs on oil change.
(10,000 miles = 16,000 KM or 1 year on standard diesel up to B5. B8 is 8,000 miles or 10,000 KM about or 6 months)
The EcoDiesel, like many modern vehicles, uses an electronic service monitoring system to identify owners when the engine is in need of an oil change. Fuel filter and water separator service are scheduled at 30,000 intervals, unless a biodiesel blend greater than B5 is used. While the engine is B20 compatible, maintenance will be required more frequently, primarily due to concerns of fuel dilution
• The 3.0L EcoDiesel has made the Ward's 10 Best Engine List for three straight years: 2014, 2015, and 2016.
• Oil changes are required as indicated by the engine's oil monitor system, but should not exceed 10,000 miles or 1 year for engines operating on standard diesel or up to B5 biodiesel fuels. For engines operating on B5 - B20 biodiesel, oil changes should not exceed 8,000 miles or 6 months.
• Fuel filter changes and draining of the fuel water separator is recommended at 30,000 mile intervals for engines operating with standard diesel or up to B5 biodiesel fuels, and 20,000 mile intervals for engines operating on more than B5 biodiesel.
• The engine's PCM monitors the diesel particulate filter (DPF) storage capacity and will reduce engine power once the filter reaches 80% of its max capacity.
