Green anti-freeze

We are installing a new boiler and the anti-freeze is bright Green, the boiler anti-freeze I have always seen was mostly red. How can I test if this is Car anti-freeze. Thanks

I'm pretty sure that green color means ethylene glycol or automobile antifreeze. Red color ususally means propylene glycol. Propylene glycol can also be clear or yellow. Propylene glycol is environmentally safe. Green colored ethylene glycol is NOT.0

I'll go out on a limb here and say this. If the antifreeze in your heating system or anywhere near your domestic water system is green it needs to be removed and properly disposed of and then replaced with the proper stuff. In my experience propylene glycol is RED. Ethylene is green and highly toxic. Unless the installer can prove with 100% certainty and confirmation that it's propylene then it's not. I'd be interested to hear what other have to say about this.Miss Hall's School service mechanic, greenhouse manager,teacher and dog walker0

Automotive antifreeze in the us usually has an additive that smells like dead fish, so it can sometimes be identified by smell. I have used propylene glycol that is dyed blue.0

Yep, seen green automobile glycol used in heating systems over the years....functional yes BUT no way kosher nor to code. Eventually the boiler will leak and you sure don't want the family pet to lap it up....it's a nasty way to die.0

Color is not a good indicator of the type of fluid. I have used Rhomar PG, blue colored, Hercules Cyro-Tek PG is pink, Dowfrost is clear, Dowfrost HD is fluorescent yellow. I've also seen red and orange colored PG.
We sell a corn based BIO glycol for hydronics and high temperature solar that is bright fluorescent green.
If it gets overheated often it all turns coffee colored, smells like a dirty locker room.
Jiffy Lube and others will recycle small quantities for you, doesn't matter if it is PG or EG as automotive applications use both now.Bob "hot rod" Rohr

Interesting. Learn something new every day. I've only seen red PG but that's probably regional. 99% of my purchases have been from Webb. You'd think color coding would be a good idea.Miss Hall's School service mechanic, greenhouse manager,teacher and dog walker0

Is there a container, SEALED container that it is in? Read the ingredience. Can you google the brand's colour and cross reference it with the colour of what is in the container. If it is some stuff in something someone gave you, give it back. You do not want ethylene at all.0
