Royal Purple 5W-30 with Motorcraft FL-820S filter here. For the record, I switched to synthetic at 125k miles (not sure what oil was ran in it by previous owner), and never really had much of a leak. The valve cover gaskets and oil pan gaskets had a slight leak afterwards, but IDK if that had anything to do with the synthetic oil. I replaced them when I had the engine and trans out last winter and haven't had a problem since.
