The Mercedes yellow is the same, made by BASF Germany for Mercedes. The
Jaguar blue, same-0-same-o. No green I have ever seen is without
phosphates. Never use green, verify all others as no phosphates e-glycol.
And even more important, complete change for new yearly to be sure
corrosion can NEVER GET STARTED. Keep the motor clean as well and you may
just get 200,000 miles from a WasserBoxer before the hoses get hard from 20
years of age and the first leak starts, but still no corrosion at all.
