I am interested in maybe trying their oil in my truck.I have used their oils before,although only in equipment that was at a plant I worked at in the early 90's.. Some oil was in service 4 plus years,oil analysis was always used to determine continued useage.A few times the oil was drained from an out of service/broken piece of equipment,rudimently filtered and poured into a rebuilt piece.Fantastic stuff I must say...Well I searched their website recently and thought well maybe. First the TBN on the 5w30 oil is a mere 6 ,isn't that really low??? Is it evn worthit???? Second,where to buy??? I googled to no avail..Anyone out there have any comments,suggestions or dealer names??? Any help is greatly appreciated.
