How many antifreeze types are there?

There are two main groups of antifreeze, mono ethylene glycol-based and mono propylene glycol-based. We recommend you to refer to the owner’s manual to find out which type your engine needs and the correct antifreeze ratio (antifreeze has to be mixed with water). Each antifreeze contains special additives to prevent corrosion of the metal surfaces in the cooling system. Do not mix different antifreezes, which will adversely impact additive performance.
