I buy a gallon of uncut (advertised good for all colors) and a gallon
of distilled water. I have an ice cream bucket marked at the 2 quart
mark. I measure 2qt of uncut antifreeze and pour it in a container
(empty anti freeze bottle), then I measure 2qt of distilled water and
pour that in. Cap it and write 50/50 on the outside. Now I measure
2qt of distilled water and pour that into the remaining uncut anti
freeze, cap it and mark that bottle 50/50.

I now have 2 gallons of measured 50/50 anti freeze (with clean water)
for less than $10. A full jug will sit upright under the back seat.
