Safer Antifreeze
Everybody knows antifreeze kills pets? Kids too! There is a less toxic propylene glycol formula available. Propylene glycol is actually used in small amounts in some pet chows.
I changed the antifreeze in my car last night. I used Prestone Low Tox from Advanced Auto Parts. It was $12 for a gallon, maybe the same as regular. Sierra and Evans also make a propylene glycol based antifreeze. It is somewhat less effective than the ethylene glycol. Still at the usual 50/50 it is good down to -26 degrees F. That should cover most of the US. It not, you can use more and go down to -76. It seems a small price to protect out pets.
The car is an 02 Cavalier and still had the original factory fill and was slightly past the recommended change. It never leaked a drop. In over 100,000 miles I never added anything. The original looked OK and is packed up in a old laundry detergent bottle to be recycled. I try to take care of my pets, car, and environment.
