Rob Peters Posted July 3, 2019 Share Posted July 3, 2019 Michael, I am thinking not many people have any experience with it and that is why there have been no responses. I have no experience in this. rob Quote Link to comment Share on other sites More sharing options...
mmccammon Posted July 3, 2019 Author Share Posted July 3, 2019 I suspect Rob that you are right. i don’t think it’s been as popular as it should be. from what I can tell it works fine in older cars. ethylene glycol is SO toxic.. a few licks can kill pets.. always felt the propylene glycol based product should get more press. mike Quote Link to comment Share on other sites More sharing options...
71MonteCarloMD Posted July 3, 2019 Share Posted July 3, 2019 Mike, I am interested to learn more and how it goes if you decide to use that product in your Monte. Quote Link to comment Share on other sites More sharing options...
imr Posted July 3, 2019 Share Posted July 3, 2019 I am no expert and I am just sparking conversation. From what i remember we have Poly and Ethinyl glycol and I will just call them antifreeze. i believe fresh clean fluid is not very bad for the environment due to the short half life, but its toxicity when consumed is very high and add that it is sweet tasting makes it appealing to animals. so when we say a friendly product is the concern primarily the environment or our pets. I personally do not believe it is a product that is harmful to the environment if clean, once used then it does become an enviromental issue. part of is job is to sacrifice itself for the longevity of our cooling system, with that it absorbs zinc,chromate, iron, copper and many more.
