Full synthetic?

[91mini]

Please bare with me fellas as this is my first brand new car and first real car (car with a V-8).

Anyway to the question at hand. I want to go full synthetic and was thinking of going with Mobil as my oil. I have done an oil change at 800 miles and used Motorcraft premium synthetic blend. I am currently at 2200 miles and want to do a change at 3000 miles. I drive 100+ miles round trip to work 5 days a week (mostly interstate) and want the engine to have a long and strong life. My questions are:

1. What would be the benifits of me personally going to a full sythetic (if any)?

2. Do I have to use a different filter then the standard Fram or (insert generic brand here)?

3. How long between oil changes is ideal for a engine running on full synthetic?

4. What brand do you recommend?

Sorry for the novel and thanks in advance for your help.

Full synthetic oil gives better lubrication and resists break down due to high temps better than regular motor oil. You can use a standard filter and I follow the traditional oil change every 3000 miles rule. I prefer Mobil 1 vs other brands.
