Thanks for your input Mokanic. From my point of view it just seemed odd that everything on the report would be almost exactly identical except for the areas that show how well the oil is holding up. I'd like to send it to a third lab just to satisfy my curiosity (I know, a total waste of money). I can't help but wonder why only those parts are different. Your right, that's a lot to expect from a $20.00 lab report but I would expect differences to show up in a more random way than in groups. I like the Schaeffers product, and my rep is just awesome! The higher lead levels don't really concern me much at this time, however I am curious as to why they seem to jump in all the powerstrokes with the Schaeffers product. That's why I'm here, to try and understand why the reports show differences in things like viscosity, etc. not point fingers. Anybody's input on this difference between the two reports is welcome from me. Thanks!!
