Important Considerations:
* MB 229.1 specification: This is the key. Don't just look at the weight; ensure the oil meets this Mercedes-Benz standard. Modern oils with higher specifications (like 229.3, 229.5, etc.) are generally backward compatible but using an older spec oil is vital.
* Oil Changes: Follow the recommended oil change intervals in your owner's manual. These older engines benefit from more frequent oil changes than modern ones.
* Climate: While 15W-40 is a good general choice, 20W-50 might be preferable in extremely hot climates.
Always check your owner's manual for the most definitive recommendations. Using the incorrect oil can significantly damage the engine.
