I'm sure it's possible, but why? Coolant is cheap and you don't need to change it every year. If your vehicle is under warranty, I would stick with OEM fluid.

You can usae Zerex G 05. It's the same thing as MB fluid, it is approved for use by MB in their cooling systems, and it is cheaper.

yes, the MB approved is a must-have. The Zerez G5 is the identical antifreeze to the mercedes and quite a bit cheaper.

Whatever you do.....do NOT use Dex-cool extended life coolant. There have been numerous complaints/lawsuits regarding this stuff.

Two gallons of G5 will be plenty for a 50/50 mix and some left over........
