Whether you can use 10W30 oil in a Dodge Charger depends entirely on the
year and engine of the Charger. The owner's manual is the definitive source. It will specify the recommended oil viscosity (like 5W-20, 5W-30, 10W-30, etc.) and oil type (synthetic, conventional, etc.).
Using the wrong viscosity oil can lead to poor engine performance, reduced fuel efficiency, and even engine damage. Do not rely on general advice; always check your owner's manual.
