I believe you will find it is not the "aluminum safe" feature you are
looking for in a "phosphate free" antifreeze". With the use a so much
aluminum in todays engines, I don't of anyone that markets an antifreeze
that is not aluminum safe. The "phosphate free" feature, that is required
by "most" Euro car makers, is to reduce the percipitation of minerals out of
the water. There is at at least one U.S. brand of phosphate free antifreeze
on the market, Quaker State. Color is not a true indicator.
