After my experience with Frog Lube, I have zero interest in any "environmentally friendly" "biodegradable" lubricants. They all look good when advertised in the best of conditions, but when the Frog Lube actually kept my BCA from going into battery because the cold weather caused it to gum up, I went back to the old faithful lubes and solvents. If the label doesn't have a cancer warning, or isn't on a watchlist by the EPA, not interested.
