Nobody seems to know why the 5.0 is using the FL500S. I have asked this question to many, Jim told me he would find out when I asked him at Miller but I have not heard back yet. I emailed FCS about this and they said if you use the 820S it will not be covered under warranty if there is a problem.
That is wierd since I understand Ford Racing sends a racing version of the 820S with the intake kit. Also after bringing the issue up with the dealer (they told me to contact FCS) they put a FL820S on my Boss during the first oil change. Even the new F-150 is calling for the 500S.
Somewhere somehow someone must know something .... S197 ??? I assume there was a reason?

I was checking filters also and found a write up on some.
I talked to FRPP and they were saying that the larger/HD race filters is what he would use.... I bought a set of 6 to get a discount and am ready now.

Motorcraft FL-820s vs Ford Racing CM-6731-FL820 Oil Filters
--------------------------------------------------------------------------------
I thought you guys would be interested in reading this comparison study because so many people are under the impression that both of these filters are exactly the same just different labels. Look at the difference in total square inches of filtering media surface, Ford Racing is 250 square inches compared to 156 square inches for the Motorcraft, that's 94 square inches less! A larger filtering surface means more oil flow and greater filtering capacity. I get my Ford Racing filters from LateModel Restoration Supply OIL FILTER, FL820 - HIGH PERFORMANCE MISCFORD for $12.99. The Ford Racing filter is built using thicker metal (noticeably heavier) for the can material and the threaded base plate is real beefy with deep high quality machined threads. I was using the K&N HP-2010 until I read this article. The Motorcraft and Ford Racing Filters both utilize a base end mounted bypass valve instead of a top dome mounted bypass valve like the K&N and Purolator models. You can read about the importance of the bypass valve location in the oil filter comparison link I have attached for you below.

Really? Do you think Ford, with two off-the-shelf filters to choose, no production end date for either, is going to recommend a filter that would have any remote chance of not being fully protective of this engine? BTW, the filter from the factory is small than all 3 filters listed. Nothing wrong with the larger filter but if you plan to follow recommended change intervals, no real need either, IMHO.

Really? Do you think Ford, with two off-the-shelf filters to choose, no production end date for either, is going to recommend a filter that would have any remote chance of not being fully protective of this engine? BTW, the filter from the factory is small than all 3 filters listed. Nothing wrong with the larger filter but if you plan to follow recommended change intervals, no real need either, IMHO.
One another note does anyone know if the anti-drainback valve is different or the same valve as the bypass valve? I use to use any equivalent for the FL1A but always use the Motorcraft on the newer 820 applications because of the anti-siphon valve.

Scott, not sure I understand the "cost" theory. The car comes with neither filter we are discussing (at least the 3 LS's than we're tampering with didn't). Haven't looked recently but I thought the cost of the two different sizes was almost the same? (I know the Ford Racing filter is higher and built better.)
Yes, we run exclusively the Motorcraft 5w-50 in all of the GT engines and the Coyote cars.
Hope I'm not offending anyone - not my intention.

I have a very complex approach to this subject. After every track day, I take my car down to my dealer first thing in the morning, have their specialty mustang tech change my oil and filter while I read the paper. Then drive home.

For the $9 in labor they charge me, it's hardly worth the effort of buying the oil and filters, taking it to a disposal facility and doing it on jack stands. The only thing I have to make sure about is reminding them of the DOT4 in the brake reservoir with a big STOP! label on it

I run redline 5w50 and K&N filters - always been a winning combo for me. I happen to be lucky enough to be able to get both locally, and relatively cheap. After my 3k oil change, I'll be sending out my next batch of Redline to Blackstone Labs for a proper analysis. We'll see what we can see then.

Filters operate in bypass mode when oil pressure to the engine through the filter media drops too low. This can happen during cold weather starts or if the filter is full and the oil will not flow at a high enough rate or pressure. The design of the Motorcraft filter is different so that it bypasses the oil straight back out without washing over the dirty media like some aftermarket filters. All of this should never happen under normal circumstances.
What I do not understand if this is a different valve since (supposedly) the Motorcraft filter also uses a anti-siphon valve. This is to stop oil draining out of the filter when the engine is not running. On the 302 it would not make a difference because of the placement of the filter. I use to think that was what the "S" stood for but I was also told it stands for "short". If that is true maybe the 820 was replaced by the 500 because it does not need the extra siphon valve.

I use the time under the car while the oil is draining to nut-n-bolt and verify that everything is still the way it is supposed to be, no strange leaks, etc. I've yet to find a shop that is as thorough as the guy who's butt is in the seat heading into a corner at 140 mph
