The 2002 Ford Expedition needs 5.7 liters (6.0 quarts) of SAE 5W-20 engine oil. Some popular oil brands for this vehicle are Castrol Edge, Valvoline High Mileage, Valvoline Advanced, Shell Rotella, Castrol Magnatec, Royal Purple, Pennzoil Ultra Platinum, and Mobil 1. Ford suggests changing the oil every 6,000 miles or 6 months, whichever comes first. Using old, thick, or low oil can lead to inadequate engine lubrication and cooling, potentially causing costly damage. It's recommended to regularly check the oil level, even if it's not yet due for a change, to prevent any issues. Make sure to check and replace the oil when the engine has cooled down to avoid getting burned. If you prefer to have this service done for you, expect to pay around $120 to $160, with approximately $50 for labor included.
