The recommended engine oil grade for a 2000 Dodge Dakota with a 3.9L V6 engine depends on the climate where you live. Consult your owner's manual for the most accurate and up-to-date information. However, a common recommendation for that engine and year would be
5W-30 for most climates. If you live in extremely hot or cold areas, you might see a recommendation for a different viscosity (like 10W-30 in very hot climates, or 0W-30 in very cold climates).
Always prioritize the information in your owner's manual. Using the incorrect oil grade can damage your engine.
