Keystone RV Forums - View Single Post - Is there a, "best," pink anti-freeze???

When I go shopping for RV antifreeze, I use these criteria:
1) good for temperatures to -50. Not that it ever gets that cold here but I know that, undiluted, it will be more than adequate for our lowest winter temp.
2) good for both plastic and metal pipes. I know that almost all of the RV lines are plastic but there are some metal components in the water pump, toilet, valves and a couple of other small items. Maybe not necessary but I buy this type.
3) Cost --- if the 2 criteria above are met, I get the cheapest I can find.

I've never seen any RV antifreeze ratings or testing of the pink stuff that would provide me with any factual and reliable data so I go with what has worked in the past for me.
