I believe the red is long life (five year change interval) and blue is two
year interval.  Mixing the two still protects from freezing, but makes it a
two year coolant!  Stick with Zerex. I use the G-05 now but also used
Dexcool for about ten years.

Did I miss the memo? Is vw coolant now red instead of blue? Can they be
mixed?

Thanks
