I don't know anything about engine oil made from cows other than the simple fact that it's probably just another "pie in the sky" bull-own-ee attempt at a money grab perpetuated once again by the same thieving-ass farmers that banded together and conspired up the plan to take a huge, stink'n crap in our spinnage .... sickening scores of unsuspecting consumers .... not to mention the farse they're delute'n gasoline with called ethanol and shoving it down America's throats .... all while the poor oil companies are barely eek'n out a living .... and have you looked around at the World lately? .... it's far too late to try and save now .... the only option left is to consume-consume-consume .... just ride this stinking cess-pool wide the freak open all the way to the end ....
