So PAGE62 is more of an expert than the MB factory engineers!
Ridiculous advice considering that the cost of the recommended fluid is so cheap.

Seems to me that unless someone has a situation in which he has access to numerous observations over a period of years, their opinions on subjects like
the effects of non-approved coolants are pure opinion and speculation. I have read posts on other lists from MB only shop owners with 30 years experience and observation of thousands of cars that emphatically state that use of non-MB approved coolant causes problems in MB cars, period.

I choose to spend the extra 5 bucks or whatever it is and follow the factory recommendations.
