You cannot determine the correct oil type without knowing the specific year and engine of your Transit.
To find the correct oil type, you should:
* Check your owner's manual: This is the most reliable source of information. It will specify the recommended oil viscosity (e.g., 5W-30, 10W-40) and type (synthetic, synthetic blend, conventional).
* Look for a sticker under the hood: Many vehicles have a sticker indicating the recommended oil type and capacity.
* Use Ford's online resources: Ford's website or a dealer's website might have a lookup tool where you can enter your vehicle's details to find the recommended oil.
Using the incorrect oil can damage your engine. Always refer to your owner's manual for the correct specifications.
