> Does anyone know if it's OK to mix different brands of antifreeze?

I recently used a case each of Prestone, Dow, and Texaco.  A week later
I dumped the last few drops from each container into one container.
Now I have about a pint of this mixture.  It has grease like stuff
floating on top and the various colors (red, green, and blue) did
not mix, they just form sort of a muddy streaked color.  I would
say that they are not compatible.  Fortunately, I just used it in 
a lawn roller and should not have to worry about anything but corrosion
resistance.  I wouldn't want it in a car.
