I think propylene glycol is used as an anti freeze in camper potable
water systems because it is supposedly non-toxic in the small quantities
that would be residual  in the water system after a flush and refill
with fresh water in the spring time.

In any case this is not the stuff for your vehicle. Stick to spec or
there is trouble ahead.
