Hello,
Which is the best engine coolant to use? I vaguely remember reading that Mercedes' own coolant is not the best - or did I get that totally wrong? Is Zerex G05 the one to use?
Thanks

Both is same.
Same thing. Exactly the same thing.

Ok, so why is the "green stuff" bad/wrong/whatever? It's what I've got in my car now...
-tom!
Merceds antifreeze has better 'chemistry' it appears wrt metal and aging and corrosion ...... not sure of the 'exact' details.

It's not very strongly pH buffered and can turn acidic over time. It's been seen to eat through an aluminum head rendering it useless. If your car has an iron head you're probably ok.
