This is only true if you're running original 37-48 water pumps with the bronze oil-lite bushing in them. Most of the repop/modern pumps (single pulley) have a sealed ball-bearing in them - instead of the bushing, so they need no oil.
I have all my stock pumps rebuilt by 'Skip' so I have his much better impellers and sealed bearings. I like this route - versus the repop pumps.
