The water pump seal if a friction device that requires lubricant to keep it healthy. Usually it is a spring loaded carbon-graphite ring turning against a steel or ceramic piece fixed in the housing. This is the parts that wears or the sliding part seizes onto the shaft so it does not push the ring against the plate. A bad bearing allowing shaft wobble will kame a pump leak real fast.

All modern antifreezes will have what is needed to lubricate the seal. Adding any type of oil can create havoc. Water soluble oils such as used in machine shops probably mix well and won’t cause any damage but I see no benefit if a good coolant is used. It seems that any of the heavy duty diesel engine coolants protect pumps very well and my current favorite is the latest products such as "Final Charge". These products also have supper wetting agents designed for use in sleeve type engines so wetting products are not needed. The down side of these products along with adding any wetting agent is that these agents lower water's surface tension. That is the benefit. However, lower surface tension means stopping small leaks becomes that much more of a challenge.

Scott, what part of the water pump are you lubing with the oil? No internal parts of the pump are exposed to the coolant, only the impeller. If you mean by "successfully treated" that you have put the oil in and the vehicles did not fail for a while after, well, hmmm....... . That is hardly a controlled experiment to test the hypothesis that cutting oil lubricates the pump. So far as I know, all cutting oils are non-polar like most oils, that is not soluble in water. mcneely
