However, as a general guideline, many 1997 E150s used 5W-30 or 10W-30. But this is NOT a guarantee. Using the wrong oil can seriously damage your engine.
To find the correct oil:
1. Locate your owner's manual: This is the most reliable source of information.
2. Check the oil fill cap: Sometimes, the recommended oil type and viscosity are printed on the oil fill cap.
3. Look for an engine sticker: There might be a sticker under the hood that provides this information.
4. Check the engine code: If you can find the engine code (often stamped on the engine block), you can use that to search online for the recommended oil.
Once you've identified the correct oil viscosity, you can choose between conventional, synthetic blend, or full synthetic oil. Full synthetic is generally the best performing and longest-lasting, but also the most expensive. Conventional is the least expensive but may require more frequent changes. Synthetic blend is a middle ground. Again, your owner's manual will provide guidance on this as well.
Do not rely on online forums or general advice. Always consult your owner's manual to ensure you're using the correct oil for your specific vehicle.
