usually the motorcraft 5/20 i get at walmart says CP on the bottom of the 5qt container. i assume that is conoco philips, right? the last couple of bottles say "LEE" and there is no CP logo to be found. i googled and found a "lee oil comp" that has some affiliation with the petroleum world, but it is vauge exactly what. What im wondering is: is the stuff in the bottle the same, despite what the bottle says on the bottom??? what exactly does LEE have to do with the motorcraft brand? thanks in advance for any clarification.
