Quite honestly until doing a bit of research I didn't realize there were different formulations of RV / marine antifreeze. Some containers I've used also mention pools, and others just mention something like "good for other uses as well". Is this one ok? I'm putting together an order from one of my local hardware stores including varied stuff and thought I'd add this to the order if it's safe to use: http://www.championbrands.com/MSDS/Champion MSDS RV-50 Blend.pdf Here's the one from the store I've typically bought antifreeze from for probably the last 30 years. Also a mixture but higher % of propylene glycol http://southwinltd.com/wp-content/u...0-RV-Marine-PG-Blend-142005-142001-142002.pdf Stay with this one instead of the Champion brand?
