What he said - there is no one oil everybody agrees on. Some swear by Ford Motorcraft semi-synthetic blend oil and a Motorcraft filter. Me, I use Mobile 1 or Castrol synthetic. If your car has over 75,000 miles or has small leaks/drips, a high mileage oil that helps the oil seals is recommended. Again, that is just my opinion. Everybody would probably agree to avoid cheap non-synthetic oil, most would agree to stick with the factory recommended viscosity or very close to it.
I recently switched to Havoline semi synthetic because it comes in 6 quart containers. It seems to be on par with the factory Motorcraft oil but cheaper and more convenient. Otherwise I only run motorcraft in my cars.
