* For warmer climates: 5W-30 is usually recommended.
* For colder climates: 5W-20 might be specified, especially if you experience freezing temperatures.
Regardless of climate, always check your owner's manual for the *exact* manufacturer's recommendation. The manual will also specify the type of oil (conventional, synthetic blend, or full synthetic) and the oil capacity for your engine. Using the wrong oil can damage your engine.
After you've consulted your manual, you can choose a widely available brand like Castrol, Mobil 1, Valvoline, Pennzoil, etc. The brand is less important than using the correct viscosity and type of oil as specified by Dodge.
