Motorcraft FL-820S, end of story. I won't use anything else on mine.
i use WIX on every vehicle in the garage!!
I have only changed the oil once in my svt since I bought it but I put on a mobil 1 extended performance filter and I know its a lot of money, its got the anti drain back feature which isn't supposed to let all the oil drain down to the pan. Is this just a gimmick or does it have any real advantage over other filters?
I stay away from Walmart and ESPECIALLY from Walmart Motorcraft filters, I've heard they aren't the same Motorcraft filters you buy at Auto parts stores. I know the real Motorcraft filters are made by Purolator (Pure one) and I've HEARD that the walmart ones are made by Fram. This is what I've read on plenty of other forums but I don't have any personal experience with the Walmart ones as I stay away from there anyhow.
