EcoBrick Bob Posted December 16, 2011 Report Share Posted December 16, 2011 We are heading on a 4,000 mile Christmas trip this Sat, and I just realized I need to change the oil (7K on it). Thought I had an extra Motorcraft 500S filter but can't find it. How big a deal is it to use a Mobil 1, K & N, Wix or other brand filter? Read something about flow thru pressure... Like it's supposed to be low so we get plenty of oil flow under load or WOT. Usually buy them from Rock Auto, but no time now. Or... should I Get RAPED buying it at my local Ford dealer?
