Nothing earth shattering here, just thought I'd share results after dumping the factory fill after ~2,500 miles from my Ford Focus RS. Does not look like the factory fill is 5w-50 even though that is what is recommended per the owners manual, which I find interesting..
FF was replaced with Castrol Edge 0W-40 + Ford Motorcraft filter.
