Mercedes coolant no more at dealership

If it were me, I’d just use the AMAM Prestone and sleep soundly at night.

This Zerex Chart says you can use G05 which is widely available at a reasonable price

BMW LC-87, MB 325.0, BASF Glysantin G48, as well as Zerex G48, even VW G11 (TL 774-C) - all the 'same', at least fully compatible.

G48 is a fine coolant - even Tesla uses it to keep their batteries cool. Mercedes is using G40 these days and dropped G05 a while ago. Both are SiHOATs, I think G05 adds on borate for wet liners.

Yes, G48 does have 2-EHA in it but the Europeans typically don’t have RTV silicone or PA66/GF33 gaskets seal cooling systems unlike GM and Toyota.
