T3 Coolant Comparison

[syncro]

I have just done a bit of research from various companies on VW coolants.

• G11 mixes well with G12+, G12++ or G13 but not with G12.
  
• G12 mixes well with G12+, G12++ and G13 but not with G11.
  
• G12+ mixes well with G12++ and G13, also with G11 and G12 but there is a loss of corrosion protection.
  
• G12++ mixes well with G13, also with G11, G12 and G12+ but there is a loss of corrosion protection.
  
• G13 mixes well with G12++, also with G11, G12 and G12+ but there is a loss of corrosion protection.
  

Now as a lot T3s have had an issue with corrosion I think that I made the correct decision with mine to stay with G11. The corrosion protection would be my main decision in selecting a coolant.
