if you are in illinois and run in the winter you probably want to stick with amsoil 5w-30. if summer and track use only use the 10w-30 or 10w-40. we run 10w-40 in our boss track cars we work on. they love it.
Amsoil with Motorcraft filter.
ford racing filter with mobil 1 extended 5w20 is what I use.
Well, I know it's still a cellulose/synthetic blended media, so it can't be that great. Nano-Fiber media found in Amsoil, Royal Purple, and a couple other house names has proven its dominance.

Just completed my second oil change using Amsoil but this time I went with the above recommended EA011 filter. Its fatter than the other one and I was concerned it wouldn't seal properly as the outer edges of the filter are out beyond the edge of where it seats on the car. After 30 miles it seems ok.
