I think that the Sierra product uses propylene (sp?) glycol as opposed to
etheylene glycol. If the product is pure propylene glycol, it is safe to
ingest. However, it seems like there must also be additives that wouldn't be
safe. Supposedly, both compounds are sweet tasting, so presumably animals
(especially dogs) will lap up coolant that has been spilled or drained on to
the ground. In the case of regular coolant, a few sips will kill a dog.

I thought that propylene glycol was only usable in high flow, non-pressurized
systems...?
