I have heard people use RV antifreeze for long term storage of their roller pumps. Since this is just propylene glycol and water does it really keep things from rusting? Last time I used some motor oil. When I went to use the pump again this year it took some effort to break things loose. I also notice there was a bit of water in the oil. I know there is not that much oil left in the pump after draining it for us but if I can avoid spraying a little oil I wold prefer that.
