* 5W-20: This is the most likely recommendation, particularly if you have the 2.7L V6 or 3.5L V6 engine.
* 5W-30: This might be an acceptable alternative in some climates or if your owner's manual suggests it, especially for higher mileage.
Crucially: Always refer to your owner's manual for the *exact* viscosity and type of oil recommended by Dodge for your specific Magnum's engine. The manual will also specify the correct oil capacity for your engine. Using the wrong oil can damage your engine.
