Are you referring to Caterpillar's Extended-Life Coolant (which is FAR different from the Dura-Cool stuff, BTW)?
I'm switching my truck to ELC when I put everything back together, and for the sake of having one fluid for both vehicles, I'm thinking on the lines of putting this in the Benz next time I flush the cooling system...
ELC also has a good anti-cavitation additive (coats the cylinder walls and acts as a sacrificial goat)...not as important with the OM6xx engines as it is with the Navistar 7.3l IDI, but still a good idea
