Oil filters?

Oil filters?
So its that time again, time to change the oil... the only thing is, i bought a motor craft fl820S oil filter for my 2010 4.0, but it seems to have a smaller one installed on it (looks like the fl500s). Im confused as to why every chart I've seen has said to use a 820, but the ford dealership i got my mustang from has a 500 on it. Can anyone enlighten me?

the FL-500 and FL-820S are physically interchangeable; same bore size and thread on the center and same gasket seating surface. Just like how you could install a Motorcraft FL-1A (the classic 302/351 Windsor filter) on a 2.2/2.5 liter Chrysler engine. maybe the 500 was used because it was a bit cheaper, or it was what they had on hand.

You can't go wrong with the Motorcraft filter unless you're running your oil beyond 7500 miles as I and others here do (full synthetic). It's rated well. IIRC, the FL500S is used on the newer Stangs but is interchangeable with the FL820S as mentioned.

Amsoil & Royal Purple are both designed for longer oil change intervals.

The Amsoil Ea filters are rated for 25,000 miles but I personally wouldn't feel comfortable going much beyond 15k miles until I did some test or analysis. I typically go 10k-12k miles on the Amsoil Ea and the Mobil1 filters.
