I'd prefer to use a Motorcraft oil filter on my wife's Villager, but I'm not willing to pay $9+ for a FL-839 from the dealer. The local Wal Mart doesn't stock the FL-839, but they do stock a FL-400S which appears to have the same thread dimensions and gasket size - diameter and thickness. The FL-400S is longer, of course.
Do you think I can substitute the FL-400S for the FL-839?
