The recommended oil type for a 2006 Ford Fusion depends on the engine it has. Ford Fusions from that year came with either a 2.3L I4 or a 3.0L V6. You
must check your owner's manual to be certain. The manual will specify the correct oil viscosity (like 5W-20 or 5W-30) and the type of oil (conventional, synthetic blend, or full synthetic).
Generally, Ford recommends using a 5W-20 oil for fuel efficiency, but again, check your owner's manual for the precise recommendation for your specific engine. Using the wrong oil can damage your engine.
