The oil filter is on the bottom of the engine.pick up your car with a jack.make sure it is secure and get under your car it is in the center and a little bit to the driver side..you cant miss it.The oil pan is right next to it.
Exact oil fill capacities are determined by model year and engine option. For 2014 Chrysler 300Ms with the 3.6L V6 the service fill is 5.9-quarts with the filter. The recommended viscosity is API 5W20 for this model and engine.
On some cars there is a reset button in the fuse panel, check with your cars manual to see if they tell you how or where to look. There is no reset on a 300m. If the oil light is on, you are low on oil, have a bad sensor, or a engine malfunction.
