Old proven

Well,
how do you evaluate a product such as a radiator antifreeze? Whether that was good or bad you knew that only when in retrospect - for years - he was out is bad.
I 'always' Glysantin participating - and it has never been wrong.
What should be the manufacturer as homework might be better to address the question what please 'contains silicate' and 'Silikatfrei' is now and to be as concrete as 'Ask the Herstellet' 'Do not mix' and.
While there is a search function on the side for the right product, but there are bicycles totally ignored. Even the workshop manual for my Majesty says only "glycol-based corrosion protection with ALU".
The question that now is the right for Glysantin, and especially where is because 'silicate' and no different in the effect you're looking for in power for a long time - without ultimately really find an answer.
Here, the manufacturer would have a duty to investigate, especially in a 'premium product' as the Glysantin depending represents. Why only 4 stars.
