My coolant level has dropped to just below the MIN. mark on my '97 Boxster. Are there any acceptable substitutes for the Porsche brand antifreeze/coolant? I have some PENTOSIN PENTOFROST SF (G001200?) that is silicate, nitrite, amine and phosphate free which seems like the right substitute, but it is a pink color, and the stuff in my Boxster is green. I have always been told not to mix colors. Advice?
