Larry,

You make the point about the MB antifreeze and other MB products better than I can. All I'm trying to say is for the owners to just read their owners manual and make up their minds on which products to use in their Mercedes. The manual states that there are a number of antifreeze/coolants that will provide the requisite(required) protection. I care not what the cost is. I always buy the best product that will do the job at the lowest price. If $13/gal is the best price for the best antifreeze, then I will buy it. But the MB antifreeze is not any better than of lot of other brands on the market, and the other brands costs less
I just found out that Autozone sells their own brand of antifreeze(made by Zerex) $0.50 less per gal than the Advanced Auto brand(made by Prestone). Of course we all know that Valvoline Oil makes the MB antifreeze and also makes Zerex, and both are orange colored. Since orange is my favorite color, I may just switch to the Autozone brand the next time I change coolants. It (Zerex)provides all the requisite protection required for Mercedes...
