I work for the company that makes this oil. I do not own the company nor am i a salesman. I set up the bill of material for each product made....What goes in to make each fluid, what bottle, cap, ect. In discussions with the lab guy I have learned that in order for any oil to be called a 15w40 for example it must meet certain criteria that is a range. It can fall anywhere in that range and still be classified as a 15w40. He claims that Shell Rotella falls near the bottom of the range. It seems they have always had a better marketing plan than product. (I expect flack for that comment so fire away)
Anyway, My employer also makes oil for Bomgaars, fleet and farm, Case IH, BP Castrol, Mag 1, Sinclair, Walmarts Super Tech, and some of the major parts houses.
Bottom line is that this oil is in the top half of the range. Any oil with the API doughnut on the back is good oil. I have been running Walmart Super Tech in my car that has 150k on it and is still going strong. Regualr oil changes are just as if not more important that what goes in so long as what goes in has the API doughnut on the label somewhere.
Just my humble opinion from what I have learned. Individual mileage may vary. Consider what you paid for it.

I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
