G12 & G13 Coolant for Audi Cars

Since I’ve owned Audis, I noticed the color of the coolant is not green but orange. My 2008 Q7 has purple pink color instead of orange as my older ones. These 2 coolant colors are. All Audis before 2008 use G12 (Orange/Red) and after 2008 G13 (Purple/Pink). The main difference between these 2 from the normal Green Color sold in the stores is they’re made for aluminum engines and NO Phosphate and Silicate. Since I don’t change coolants on my car, only add little when needed, instead of buying the expensive original G12 or G13 from the dealers, I use dex-cool coolant for G12 and Audi/VW G13 online.
