Last automotive A/F I looked at WAS already a 50/50 mix, I imagine they are trying to keep the price point lower.

Not sure about the EPA regulations now but at one point Automotive A/F was a hazardous material so dumping it into a sewer system was a bad idea.

It is pretty toxic stuff, if it is drank it can crystallize the kidneys.. Then you die. Kills lots of pets each year... I'd stick to something else.

It is against federal law to dump any form or ammount of ethelene glycol Engine antifreeze) in any watershed,on the ground,in any sewer system or in any waterway.I was in the marina business for quite a few years and when we were winterizeing boatsthe coasties would stop for a visit every week or so and sample the AF we used.We bought 100% (undiluted) polypropelene glycol ,slush point -200 deg f )and diluted it to schive a -20 deg slush point.This we used in engines,water systems got rv watersystem af.Thecoasties would come around in the spring too and check to see what was comming out of the exhaust when we started up boats that were winterized.The 100% polypropelene is what I jugged uo and used in my black/grey tanks because it was free,and could be diluted down as far as 400% and still have a slush point of around + 10 deg.
