It helps when we do a cursory search via the above top right box provided on PackardInfo's home page, since most of these questions have been answered. Repeatedly.

I'd refer you to the below, from the tech info tab of www.no-rosion.com homepage. You'll have to visit this tab on their homepage to access the below overview of research results. Again, i do not work for nor own stock in No-Rosion, but we've found them to be reputable, initially producing a coolant preservative for industrial cooling towers, vastly more expensive and a harsher environment than our vintage lawn mower engines.

Q. Should I switch to a waterless engine coolant to avoid issues with water?

A. We recommend against it. There are a number of heat transfer and performance limitations associated with waterless engine coolant that make it less than optimal. This is especially the case for older engines with non-hardened valve seats. We spent 9 months researching waterless coolant, both in the laboratory, and in a fleet of test vehicles.
