I just don't understand why anyone would want to "risk" their car with a different coolant when Mercedes specifically recommends against it, especially when we're only talking about a difference of $1 - $2 per gallon, in a car that is worth about $10,000.

We know that Mercedes coolant is different. It is yellow, it has a neutral Ph, it contains silicates to keep the water pump and hoses in good shape, and it doesn't contain phosphates.

Take my experience as a lesson. I switched from Mercedes coolant to the green stuff at the 120,000 mile service, and within 2-3 months, 3 different hoses burst a leak, and my water pump went out.

Why would you risk your car for $1 or so difference???????????
