I dont understand why people waste their money buying that pre-mixedanti-freeze. It's half water. Are people that lazy that they cant mixthe water with the AF themselves? Here are some figures. A gallon ofthe pre-mixed stuff sells for around $8. A gallon of the pure AF isselling for about $11. So, for $8 you are getting a half gallon of AF(mixed with a half gallon of water), or for $11 you get a full gallonof pure AF. If your car requires 4 gallons in it's cooling system,you will spend $22 for the AF and add 2 gallons of tap water whichcosts pennies at most.Or, you can buy 4 gallons of the pre-mixed stuff at a cost of $32.Thus, you save $10 mixing it yourself. I dont know about you, but $10is a decent saving for doing nothing but filling those AF jugs fromthe tap and adding it to the radiator. The only thing is you got torun the engine for a few minutes to get the stuff mixed in the engine,which is no big deal if you pour it in right before a trip to town.Yea, I've heard the stupid excuse that "I might not get an even 50-50%mix. Well, I;ve been adding AF to cars for 40 years and it's not aprecise science. I'd rather have a little too much AF than notenough. Too much water will freeze. Pure AF is supposed to freeze,but I've never had a jug in the garage freeze solid on even thecoldest winter days. If you need 4 gallons total, add 2 gallons of AFand you'll use most of the 2 gallons of water, and will end up with 50to 60% AF, and that will work just fine. Not only do you save money mixing your own, but think about all theextra plastic bottles that haveto be made, transported, and recycled,just to sell a half gallon of water. People who buy this pre-mixedstuff are not very intelligent if they cant figure this out....The only winners are the companies that laugh on their way to thebank, for selling a half gallon of water for a hefty price.

Some people live in areas where the tap water may have minerals in it that may not be compatible with a vehicle cooling system. I don't havethat problem where I live so I mix with tap water. You can also buy distilled water at most drug stores if you have hard water from yourhome's city or well water supply.TDD

Why do people buy the pre-mixed anti-freee?

Steam irons are getting rare, but still exist.

There are tens of thousands of people using the other equipment. My son makes a good living supplying home respiratory equipment it just in a small area.

Depends on the fish and depend son what is in your water. Most are from other locations of the world and some are quite sensitive to what is in the water.

Agree on that.

Humidifier, usually for use in a small room

I'm not a doctor,, but I imagine some tap water can be bad for an open wound, depending again on mineral composition.
