Protection -30°C/-22°F
AOT Technology
Nitrite free / Amine free / Phosphate free / Borate free / Silicate free

TYPE OF USE
MOTUL INUGEL OPTIMAL is a ready to use cooling liquid, based on monoethyleneglycol, using
organic additives (AOT).
Strongly recommended for all cooling systems : passenger cars, heavy duty, construction and
agriculture vehicles, gardening, ships, stationary engines …

PERFORMANCES
STANDARDS AND MANUFACTURER SPECIFICATIONS : Refer to chart.
Contains a bitterness agent to prevent from drinking : coolants and antifreezes have a sweet
taste but are harmful.
Cooling system optimal protection from freezing and metallic parts from corrosion.
AOT technology provides an excellent thermal exchange and then engine cooling efficiency and
prevents from boiling.
This organic technology provides anti-corrosion properties that remain while high temperature and
ageing. Low corrosion inhibitors consumption allows extended drain intervals. Water pump protection,
avoid cavitation.
Seals, durits and plastic parts friendly.

RECOMMENDATIONS
Ready to use, do not add any water
Drain intervals : Refer to the manufacturers recommendation.
Do not mix with non organic products.
This product should not be used to protect drinking water systems against freezing.
