Distilled water is basically pure water with no additives, chemicals, or dissolved minerals that might affect stuff when the water is boiled away.

 

Yup. A friend of mine learned the hard way to not use any other water with his fd. Last week my light would illuminate (coolant light) but then I'd throw it in neutral and it would turn off. Got home, and added some distilled, works just fine.

Distilled water, just like the name, these water came from *Steam*, which means its very *pure*, H2O only product.

Something that your car will like, if your weather never reach 0, you can even run mostly water.
