Depending on the trim level you selected for your 2004 Ford Expedition, it could be equipped with either the 4.6L V8 or the 5.4L V8 engine. No matter the engine size, both require 6.0 quarts of SAE 5W-20 full synthetic oil. While you can temporarily use SAE 5W-30 if necessary, it's not advisable in the long run due to the possibility of increased friction from the thicker oil causing premature engine wear and potential early failure. To maximize your Expedition's lifespan, it's recommended to opt for the manufacturer's specified oil with the lowest weight numbers, even if it means spending a bit extra on each oil change.
Why do I need to top up my motor oil frequently when there are no visible oil leaks or exhaust smoke?
Which type of oil am I allowed to use if I have 5W-20? Do I necessarily need synthetic oil or is there an alternative?
In 2004, both the 4.6L V8 and the 5.4L V8 engines in the Ford Expedition require 6 quarts of synthetic 5W20 oil.
