However, generally speaking, a 1992 Dodge Dynasty would likely use conventional 10W-30 motor oil. However, check your owner's manual to confirm the correct viscosity (like 10W-30, 5W-30, etc.) and oil type (conventional, synthetic blend, or full synthetic). Using the wrong viscosity can damage your engine.
If you don't have the owner's manual, you can try searching online for a digital version based on your vehicle's VIN or engine code. You can also consult a local auto parts store; they can look up the specifications for your car based on the year, make, and model.
