The recommended motor oil for a 2007 Dodge Caravan depends on the engine it has. There were several engine options available that year. To know for sure,
you need to check your owner's manual. It will specify the correct oil type (conventional, synthetic blend, or full synthetic) and viscosity (like 5W-20, 5W-30, etc.).
Without knowing the engine, I cannot give you a definitive answer. Using the wrong oil can damage your engine. Always consult your owner's manual for the most accurate information.
