99% of cars made in the last 20 years have aluminum heads and the vast majority of cars in the last 10 years also have aluminum block. They all run on cheap green coolant. What makes Mercedes special?

It's a matter of the Engineers designing the car to match the HOAT anti-freeze, as much as the anti-freeze matching the car.

It'll run just fine with other anti-freeze formulations, but it'll last longer with the right stuff.

You'll live a long time on a diet of Big Macs.
