To find the correct oil weight for *your* Dodge Charger, you should:
* Check your owner's manual: This is the most reliable source. The manual will specify the recommended oil viscosity (weight) based on your specific vehicle's engine and operating conditions. It will often list different weights for different temperatures.
* Look under the hood: A sticker under the hood (often near the oil filler cap) might also list the recommended oil type and weight.
Generally, modern Dodge Chargers often use 5W-20 or 5W-30, but this is not universal. Using the wrong weight oil can damage your engine. Always consult your owner's manual.
