Jay, I just checked out your link (didn't see your post before I posted).

Yes, it states that it's not only Daimler-Chrysler-approved for all Mercedes engines, but the Technical Bulletin states that it's Mercedes Benz-approved, which is a very specific statement. I would feel comfortable using this product on all my vehicles.

The Zerex G 05 Technical Bulletin gives good specifics on its product. I'm trying to compare it with Mercedes coolant specifics, which I cannot find. Both are glycol-based, phosphate-free, with corrosion inhibitors, defoamers, and silicates. I find that the Mercedes coolant contains Sodium Tetraborate and Sodium Benzoate, not found in Zerex G 05. I'm not sure of the significance of these two chemicals.
