Well, an "embargo" is an economic boycott or trade barrier (i.e. Cuban sugar can't be sold in, or imported to, the US) -- I suppose you could call the military and political situation a "barrier," but what the Germans faced is more correctly called a "blockade."
[QUOTE="dworthy"]The OEM part is always a good choice. Of course Fram does make a microfilter, like a lot of others, but does it interrupt flow? Could it filter better and clean the impurities out of oil better? I am not an engineer, but I am sure that we have several on the board who could answer these thought provocating questions.

I dunno, but what I will say is that when I could use a larger filter (i.e. a 50% larger truck filter on my small-block Chevy, as opposed to the passenger car version), I use it. My reasoning is that there will be less restriction due to the increase in surface area and thus less of a chance the bypass will open (except I blocked the bypass in my '57 Chevy with a 1/4" NPT pipe plug
). However, unless there are any real alternatives for an M30, the issue of which filter to use is moot -- AFAIK, only "OE" style filters are available.
