Great product for my 2005 Mercedes C230. I have searched many forums and said this is the best product for my car and it works really great. My car gauge no longer shows overheating and no more annoying warning light. As stated on the product, this coolant is used by Mercedes in all of its vehicles. Some of the reasons to buy. 1) It's a 50/50 solution, so pre-mixed, no need to add water. Just pour coolant into the container. 2) Mercedes recommends the coolant of their choice. 3) The price is lower than local retail store.
