The 2014 Dodge Charger's recommended oil type depends on the engine it has. There were several engine options available that year. To know for sure, you need to
check your owner's manual. The manual will specify the exact type and viscosity of oil recommended for your specific Charger's engine.
Generally, Dodge recommends using oils meeting API SN or SN Plus specifications. The viscosity (like 5W-20, 5W-30, etc.) will also be specified in the manual and will depend on your climate and driving conditions. Using the wrong oil can damage your engine.
