I run Mobil 1 5-w30 and a Motorcraft filter (FL-2005) as I assume you do as well. I run it for 5,000 miles, regardless of how I drive. Mobil 1 is a full synthetic oil, and I believe a 5,000 mile change interval is more than sufficient. The oil could probably go 7-8,000 miles with out a problem; but I am anal and like to change it more often (after all, its a very cheap insurance). If you spend alot of time on the track, or you have some sort of forced induction you might want to change it more often. For a street machine 5,000 miles should more than fine.

M1 is usually good to 10K but like they say, you can never change your oil too often!

Depends a lot on your driving and the condition of your engine. If you flog the car hard, then you will need to change it more often than someone who drives it gently. If you drive short distances where the oil never gets full warm, you will need to change it more often. Basically, my opinion is, that in average, mixed use conditions with an engine in good shape. Mobil 1 will still be perfectly good at 7500 mile change. If you do mostly highway, 10,000 would be no sweat.

keep in mind that even ford recommends a 5K oil change interval (according to my my manual that came w/ the car). they use a partial synthetic, too. w/ M1, you could easily go to 10K, but i'd recommend changing the filter halfway through that. should only cost you half a quart of oil max.

personally, i run M1 w/ a Motorcraft filter and change it every 4-5K. better safe than sorry.

I run Mobil 1 5w-30 for about 5,000 miles before changing the oil and filter... No problems here.
