Ah, the great oil controversy comes around again. Was getting worried, the cycle is a little late this year. Thank goodness we live in a society where we can make choices.
Has anyone ever had a really bad experience with a used car salesman? The marketing executives associated with some products (especially lubricating oils) seem to take this approach. They'll tell you anything you want to hear. Conversely, there exists excellent and legitimate information on the science of Tribology (study of friction, lubrication, and wear) and, more specifically, lubricating oils for internal combustion engines, all to be found via internet searches. For those really interested in how oil works, the chemical formulations, and additives used, this is the way to proceed. To believe in advertised info, questionable testing devices, or the color dye used in a lubricant, well, this doesn't do it for me. Too much like the used care salesman's pitch.
I think everyone should use the oil that works best for them.
