I also buy the uncut stuff and use the previously empty prestone bottle,
pour half of it into there, and add water to both. Now you have 2 gallons of
mixed up coolant. I looked and looked to find out if prestone really was
phosphate free and found that alot of the manufacturers don't really label
it well at all.
I just got a couple gallons of the VW stuff given to me. I jokingly said to
someone that i could use about a spare 4 gallons of it.....
and it showed up.
