I've been using Prestone 5/150 for a few years now. I have never added
separate water pump lubricant. Recently, I'm doing the flush and fill deal on
my other two cars, and I wanted to read up on water pump lubricant. Neither
the Zerex nor the Prestone bottle said anything about water pump lubrication
qualities. I was curious how many of you folks add lubricant.
