Stocking shelves at work today, realized the labels on our oil bottles were a tad bit different, now the 10w40 is SN, going from SL, and the 10w30 is SN going from SM, all good products regardless, many taxis use these oils around here, especially the 10w40. All our in house stuff is made by Warren, fuel additives, etc, I have used some, with no ill effects in my truck (ie, Power Steering fluid, Brake Fluid, etc) never the oil, Should get a VOA done on it. Ah well, just giving everyone the update in the SE USA that they have upgraded in a sense.
