Scott, you have been saying this on here forever.  I have asked several dealerships and radiator shops about this, because of your advocacy.  The dealerships have stated that if they knew someone did that on a vehicle under warranty, the warranty would likely not be honored.  All, dealerships and radiator shops alike have stated that the water pump is internally lubricated and that any oil in the coolant would not have any effect on lubrication.  they all stated that the only materials that should be in the coolant system are coolant mixed 50:50 with water.

Have you any data concerning this, or is it just a belief?  Have water pumps with and without the treatment been compared in a controlled experiment?

Thanks, mcneely
