i believe the analysis that the above guy is rattling on about being supported by cummins was discussed by bob is the oil guy. if im not mistaken.... who cares really. the cummins oil may be in the top group but they sure aint the only ones up there i see shell synthetic. (not a cummins product), pennzoil (also not a cummins product) and a few others that are not cummins products. the test has merit because well just making a common since observation. you get out what you put in. you put in *****. guess what your gonna get out. *****.

Sorry if my "rattling on" is boring you. Obviously you missed the point about not taking everything you read on the internet as indisputable fact. It wasn't the idea that there were other oils rated in the top 5. It was the idea that a good old dino oil would sweep the board (even over popular synthetics) while oddly bearing the cummins stamp of approval from a "independent study" sponsored by a cummins site.
If you can't identify the reasonable doubt, then I implore you to continue clinging to your sacred Chevron/Esso oil relabeled for your green and yellow loyalty.
Of course, everyone can use whatever they like. But you must consider where loyalties lie and where your facts are coming from when you try to use them for product comparison.
