Well, I have no future plans to sell my 560SEL, so the only person whom I will be costing money is me

. That having been said, you probably have a point when you say that the OE coolant has helped the longevity of your car's cooling system. I, on the other hand, have had to replace the radiator, due to a leak. I might add, that at the time, when the radiator started to leak from the core, it had a yellow-gold colored coolant in it, which I assume was MB coolant. It didn't seem to help the situation any, although any radiator lasting almost 20 years seems to be a good record. The green was put in as a matter of necessity and ignorance

. It was the only thing available to me other than dex-cool. I honestly didn't know any better. I intend to replace the green coolant with G-05 in the very near future. I will probably replace all of the hoses at the same time. That having been said, my MB is a gas engine model, your 126 being a diesel would probably run forever on pure water provided it never got cold enough to freeze up

. Anyway, I appreciate your opinion, Mr. Chase. But, no I do not like my Mercedes Benz. I LOVE my Mercedes Benz. And if I truly thought that using something other than Mercedes Benz Approved Anticorrosion-Antifreeze would cause any harm to it, I would run drain it right now, and drive my one of my other cars as fast as I could tomorrow morning to the nearest MB dealership, and buy a case of it so I wouldn't run out anytime soon. I have been riding in and driving Mercedes Benz autos my whole life. The first car I ever rode in was a Mercedes, belonging to my father, which took me home from the hospital after I was born. So, even though we don't exactly agree on what to do as far as coolants go, Mr. Chase, I respect your devotion to Mercedes-Benzes.
Thanks, and God Bless,
Dave.
