I read all their claims and watched all the video's

It works by reducing surface tension (like soap would) and resulting in smaller bubbles. Ok that makes sense.

But...

Bubbles would only occur above boiling point anyway, now looking at my BMW expansion tank cap it says 200 on it, that's 200Kpa release pressure.....Why? well BMW (and everybody else) worked out somwhere in the last half century that by pressurising the cooling system you also get smaller bubbles, in fact at near 200Kpa I am sure they would be particulary small. Interestingly, the more stressed the cooling system, the higher the pressure, resulting in smaller bubbles and increased efficiancy, very nice self regulating this factory concept.

I then did a high school type test (the one where you float a pin inside a glass of water, on top of the water on the surface tension) Normally one adds a bit of soap to reduce the surface tension and the pin drops to the bottom of the glass.

In my case I added a single drop of BMW antifreeze.... Guess what the BMW antifreeze also reduced the surface tension and caused the pin to fall to the bottom. This seems to imply it has the same effect as the other product.

Now I'm wondering where the advantage of using this product over or with the factory setup is?

Anybody care to enlighten me
