The type of oil recommended for a Ford Aerostar depends on the year and engine of the vehicle. Ford Aerostars used different engine types over their production run (1986-1997). You
must consult your owner's manual to determine the correct oil type and viscosity for your specific Aerostar.
The manual will specify the weight (e.g., 5W-30, 10W-40) and type (conventional, synthetic blend, or full synthetic) of motor oil recommended by Ford. Using the incorrect oil can damage your engine.
