Should be stated on the oil fill cap. If not, I would go with the 5W-30. ---

There is your answer. “owner’s manual it says 5w 30” What does this mean? “but I buy if told me it should be 5w 20 “ Mobil One 5W-30 is more than adequate for this engine. ---

Either will do. Ford did backspec several engines (the SOHC 4.6L being one of them) for 5W-20. The move to 5W-20 was mainly done for CAFE reasons. 5W-30 is perfectly acceptable if that’s what you want to use. ---
