What antifreeze is best for your c230?

For a Mercedes-Benz C230, it's best to use a high-quality antifreeze that meets the manufacturer's specifications, typically a phosphate-free, ethylene glycol-based coolant. Mercedes-Benz recommends using their own brand of coolant, the MB 325.0 specification, or an equivalent that meets the same standards. Always check the owner's manual for specific recommendations regarding the correct type and mix ratio.
