[s-cars] Coolant compatibility?

If Zerex has a "mix with any color" antifreeze, as does Prestone, then you 
should be all right adding it. But of course, this is my guess.  I can't 
imagine that you can't find Prestone, " mix with any color" anywhere.  That 
brand is sold even in hardware  and grocery stores.

So, if the antifreeze turns muddy after a few days, it was not compatible. 
Then you need to purge several times with distilled water and refill with 
new product.
