The MB Factory Approved Service Products booklet recommends that we only use MB anti-freeze & brake fluid products?

Is this just a marketing ploy, or are the MB products really that superior.

MB COOLANT is a GOOD idea to use . . .

any HIGH QUALITY DOT4 Brake Fluid . . . is OK . . .

I recommend using mb liquids.. its like using regular 87 than 92 supreme hehe.. you want the best for your ML and not worth saving the couple $$$.. You can still use other brands for engine oil (my dealer is currently using 15w40 sythentic quaker state).. and windshield washer liquid.. but the rest I stick with mb.. your car is not cheap toy!!
