Okay, quick question. I have a really good reverse osmosis water filter system. Will that water be good for mixing down the anti-freeze? Or do I really need to get distilled water?

I've used RO water with my car and haven't seen any problems.

dude lol, distilled water is like 70 cents a gallon

Most people use regular tap water, so your water should be at least that good. Distilled is better. Even better is de-ionized water.

I believe RO water is about as peer as can be.. I know it takes something like 10 gallons of tap water to make 1 gallon of RO water...this is because its soo refined/purrified. I dont see it being any problem to use.
