RV antifreeze is the same stuff they use when winterizing boats. It is biodegradable and supposed to be safe. Trying something new this year and leaving a little in the block to mix with any water left in any pockets anywhere in the block. Hopefully this will help avoid freezes and help avoid all the rust inside the block I've been seeing the last couple of years when I first start it up (hooked up to the hose) in the spring.
