What kind of oil do you use? Synthetic or Regular?

Also, if you use Synthetic how often do you change your Oil?

Motorcraft Synthetic Blend 5w-20... Change every 4-5K miles...

Penn synthetic, every 4500.

Motorcraft Synthetic Blend 5w-20 and a Motorcraft Filter every 3K. I prepiad for a 3yr-35k servive package when I bought my truck. After that it will get Mobil One full synthetic 5w-20 and a Motorcraft filter.

i use regular oil either 5W-20 or 5W-30 and i use either a Fram or Motorcraft oil filter. If i am going to be driving it hard or towing nething during that time i will use the recommened 5W-20 and a motorcraft filter. I think 5W-30 works fine and it is a lot easier to find.

i think i might switch to a synthetic blend from here on out when i change my own oil

I know that I am ignorant on this subject, so don't laugh. What are the advantages of a synthetic oil over regular oil?
