Moving on a tangent, why do you garage the car? I live the other side of
The Pond where the winter temperature rarely gets to -17C but is
frequently sub zero. Putting an auto after use in a garage encourages
those little russet creatures to invade the vehicle.

For a great part of Eastern Canada, -17C is just a cool day and nothing to
worry about.

I don't know the location of the person that started this thread but
sometimes the garage interior is much colder than -17C in some parts of
Eastern Canada.
