Motorcraft 5W-30
Viscosity: 5W-30
Commonly used in many Ford petrol and diesel engines, depending on the model/year.
Good balance of cold-start protection, fuel economy and engine protection.
Always confirm the vehicle's required Ford specification, not just the viscosity.
Motorcraft 5W-20
Viscosity: 5W-20
Designed for engines that specifically call for a thinner 5W-20 oil.
Often chosen for fuel economy and easy cold starts.
Also requires checking the Ford specification required by the particular engine.
Important: 5W-20 and 5W-30 are not interchangeable just because both are 5W oils. The owner's manual/oil specification should determine which one to use.
