I dont understand why people waste their money buying that pre-mixed
anti-freeze. It's half water. Are people that lazy that they cant mix
the water with the AF themselves? Here are some figures. A gallon of
the pre-mixed stuff sells for around $8. A gallon of the pure AF is
selling 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 gallon
of 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 which
costs 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 $10
is a decent saving for doing nothing but filling those AF jugs from
the tap and adding it to the radiator. The only thing is you got to
run 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 a
precise science. I'd rather have a little too much AF than not
enough. 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 the
coldest winter days. If you need 4 gallons total, add 2 gallons of AF
and you'll use most of the 2 gallons of water, and will end up with 50
to 60% AF, and that will work just fine.
Not only do you save money mixing your own, but think about all the
extra plastic bottles that haveto be made, transported, and recycled,
just to sell a half gallon of water. People who buy this pre-mixed
stuff are not very intelligent if they cant figure this out....
The only winners are the companies that laugh on their way to the
bank, for selling a half gallon of water for a hefty price.
