Actually the lower the number the thinner the oil. "Cleanliness" would be API rating if anything. Absolutely correct how multi-viscosities formulated. But think about implication -- do you really want to put 5 or 10 weight oil in anything? Maybe if you lived in Nebraska. Re: stuck oil filters -- leave any brand oil filter on car too long and this can happen. Or sometimes gasket separates from filter and stays stuck to block (will leak if you don't remove before new filter). Yet another reason to change oil timely... Re: different oil filter housings -- WIX has 3 separate factories in Gastonia. May be source of 3 different internals, as well as external differences.
