The 2004 Ford Explorer XLT's recommended motor oil type depends on the engine it has. There were several engine options available that year. You
must check your owner's manual to determine the correct oil type for your specific vehicle.
The owner's manual will specify the recommended viscosity (like 5W-20, 5W-30, etc.) and the type of oil (conventional, synthetic blend, or full synthetic). Failing to use the correct oil can damage your engine.
