Why was buying the Schaeffers 9000 a waste of money? Because they have Group III basestocks as a component vs. full PAO or group IV/V? I always thought that the performance of the final product was a better measuring stick of an oil's quality. So far I have yet to read on this board where Schaeffers was less than excellent and the price still where one can afford to use it! As far as Schaeffers being jerks to deal with, in what way?
