Si-OAT coolants mix silicates with HOAT. HOAT coolants typically mix an OAT with a traditional inhibitor, usually silicates. Typically, OAT antifreeze contains an orange dye to differentiate it from the conventional glycol-based coolants (green or yellow), though some OAT products may contain a red or mauve dye. However, since 2018, they have moved on to G12EVO (TL 774-L) which no longer contains glycerol. To achieve interoperability between applications, neutral, non-proprietary or open standa...
