It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval.

Compatibility notes
- If your owner's manual calls for MS-12106, PEAK lists that code for this product. Read the exact wording above, and confirm against your manual.
- Chemistry is listed as OAT. Mixing different chemistries can shorten coolant life. See OAT vs HOAT vs IAT and use the mixing checker before topping up.
- Colour is listed as Purple. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
- Sold as a concentrate: dilute with distilled or deionised water as the label directs. See premix vs concentrate and the freeze and boil calculator.
