I guess you should go with what the owners manual recommends. For Fords, think they recommend 5W-20. If you want synthetic you could get the Mobil 1 0W-20 or the Castrol 5W-20.

If you go for a "true" PAO/Ester synthetic or a quality blend such as Schaeffer's they will be better oils at 2+/- times the price. If the synthetic is a Group III then I don't think you'll see much improvement over the Ford spec'd oil, espcially with the Motorcraft or Pennzoil 5W-20. And of course the price will substantially more. If you're changing oil every 3,000-5,000 miles is it worth it to go with a more expensive true synthetic oil. That's up to you. Whimsey
