How to find the right oil:
1. Consult your owner's manual: The most reliable information is found in your vehicle's owner's manual. Look for sections on fluids and lubrication.
2. Check your engine oil cap: The oil cap on your engine may have a sticker or inscription listing recommended oil specifications.
3. Contact a Mercedes-Benz dealer: A Mercedes-Benz dealer or authorized service center can provide you with the exact oil specifications for your 2003 E320.
4. Use a reputable online resource: Websites like "Mobil," "Castrol," or "Valvoline" can offer oil recommendations based on your vehicle's information. However, always double-check with your owner's manual or a dealer.
Important note: Using the wrong oil can damage your engine. Always use the recommended oil for your vehicle.
