However, common oil types for that era of Caravan engine would likely fall into these categories:
* SAE 10W-30: This was a very common viscosity for that era.
* SAE 5W-30: This might also be an option, particularly if you live in a colder climate.
The owner's manual will also specify whether to use conventional, synthetic blend, or full synthetic oil. Again, check your owner's manual for the definitive answer. Using the wrong oil can damage your engine.
