What's the recommended type of non-toxic antifreeze to use for winterizing a GT-40?

RE: What

I don't know that there is a recommended one but sea brite (I think that is the name) works real well. Just make sure the antifreeze isn't green and that it has corrosion inhibitors in it.

RE: What

There are two brands of GREEN Propelyne Glycol (same active ingredient in the RV stuff) enviro friendly AF that I know of. Has engine friendly additives and is not as harmful to the environment. One is Sierra Antifreeze and the other is Prestone Low-tox. The common belief that all green AF is ethelyne glycol is false as these are two GREEN AF's that are PG.
