May I add one more car to this train of thought on anti-freeze?
For sake of all the animals in the word, please use Sierra or Prestone
Low-Tox, that does not poison our pets the way regular glycol anti
freezes do. Every time I get a new car into my shop, the first thing I
do is take out the damn poisonous antifreeze. My dog and two cars share
my shop and all of them are too precious to be lost just because the
regular antifreeze is a dollar cheaper.
I will step down off my soap box down, please resume your normal
activities.
