Prestone LowTox® Antifreeze/Coolant

[PDoyle]

Found this stuff at a Walmart store. Not sure if it is a good choice.
Is there a regular Prestone green anymore? Or Is everyone using extended life Prestone and distilled water for flushing the radiator?

Hello, is this thing on????

I just bought some Zerex "regular green" coolant at NAPA. They usually carry their own branded "regular" version as well, that's what I normally get.

In my opinion, "low-tox" coolant is a gimmick. Yes, propylene glycol is poisonous to dogs and humans, but it degrades quickly, and when well-diluted is really a non-issue as far as pollution/contamination. (Nowhere near the same as say, tossing a bunch of used motor oil on the ground.)

I run the "low-tox" stuff... Works great.

Ok, thanks.

So, as long as the antifreeze is green and not a 50/50 mix, 2 gallons of green and 2 gallons of distilled water are the best solution for the coolant system?

Anybody run the “low-tox” Prestone stuff nowadays? Any reason to use this instead of the regular Prestone green or vice versa?

It's safer for dogs, maybe

it's not as tasty but it will make some crazy clouds if you put it in your vape.

Thanks, I was afraid to ask

Seriously though if there’s a safer option for pets etc. why wouldn’t all antifreeze be formulated this way?

As with most things, cost and convention is the most likely answer.

I'm also curious about this. I think there's also a "Sierra Antifreeze."

One report of it being okay is good to hear, but more reports of a positive outcome would be nice before making such an attempt.
