To determine the correct engine oil for your Mercedes ML350, I recommend checking your owner's manual or consulting with a qualified mechanic. The best oil will depend on factors like the year, engine size, and driving conditions.
Here are some general guidelines to consider:
* Viscosity: The owner's manual will specify the recommended viscosity grade, typically a 0W-40 or 5W-30 for most modern Mercedes engines.
* Type: Mercedes-Benz recommends using fully synthetic engine oil for optimal performance and protection.
* API Certification: Ensure the oil meets the American Petroleum Institute (API) certification requirements for your engine.
* MB Approval: Look for the MB approval code on the oil container. This indicates that the oil has been tested and approved by Mercedes-Benz for use in their vehicles.
Always follow the manufacturer's recommendations for engine oil and consult a qualified mechanic if you have any doubts.
