A good coolant/antifreeze also protects your internals from corrosion and scaling, and protects and lubricates your water pump- some thing that your average 'Red wala coolant' won't even dare dream to do
This one wear names like Ferrari, Lamborghini, Bentley, Bugatti, Rolls Royce, Maybach, Mercedes, BMW etc on the pack, so you can imagine how good it has to be; probably the best in the world.
I wouldn't recommend mixing any sort of coolants unless you know exactly what you're doing i.e. base chemicals, service life, corrosion exhibitors, ph value etc for both samples.
