Frigutec® engine coolants

Frigutec® M-OAT

Frigutec® M-OAT is a premium class hybrid engine coolant concentrate based on 1,2-ethanediol (MEG). M-OAT stands for Mineral and Organic Additive Technology. This means that with Frigutec® M-OAT a mineral additive system and an organic additive system work together to increase performance.

Frigutec® M-OAT provides long-lasting corrosion protection for engines made of cast iron and aluminium or combinations of the two metals as well as cooling systems made of aluminium or copper alloys and protects against overheating and frost. Frigutec® M-OAT is free of nitrite, amine and phosphate. Frigutec® M-OAT complies with most European and international standards such as ASTM D3306. We recommend Frigutec® M-OAT for a number of OEM standards such as VW 774-C (G11).

Applications

Frigutec® M-OAT offers year-round protection against frost and corrosion.
Frigutec® M-OAT concentrate must be diluted with water before use! We recommend a mixing ratio of 1:1 in volume with demineralised or distilled water. Under no circumstances should Frigutec® M-OAT be used with less than 33 vol.% or more than 60 vol.%.

Miscibility with other engine coolants

Frigutec® M-OAT concentrate only works optimally if you empty the entire cooling system, rinse it and fill it completely with Frigutec® M-OAT mixed with distilled water in a 1:1 ratio.
In principle, Frigutec® M-OAT can be mixed with all commercially available hybrid engine coolant agents based on 1,2-ethanediol (MEG) with a mineral and organic additive system. However, each manufacturer has found and tested a specially optimised composition of inhibitors which, when mixed with other radiator antifreeze agents from other manufacturers, still work well, but no longer as optimally as Frigutec® M-OAT alone.
In the event of a warranty claim, it is often impossible to assign the cause that triggered the warranty if several different makes have been used.
Therefore, we recommend the use of Frigutec® M-OAT only.
