Whether 10W-30 motor oil is suitable for your Plymouth Voyager depends entirely on the year and engine of the vehicle. Your owner's manual will specify the recommended oil viscosity and type. Always consult your owner's manual for the correct oil specifications.
Using the wrong viscosity oil can damage your engine. While 10W-30 is a common viscosity, it might be too thin or too thick for your Voyager's engine depending on its age, operating conditions, and the manufacturer's recommendations.
