MOTUL INUGEL OPTIMAL
Ready to use cooling liquid
Anti-corrosion and anti-freeze,
Protection -37°C / -35°F
OAT Technology

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

PERFORMANCES
Optimal protection of cooling systems against freezing and metallic parts against corrosion.
OAT coolant technology provides an excellent thermal exchange and therefore improves engine cooling efficiency and prevents from boiling.
This organic technology provides anti-corrosion properties that remain at high temperature and aging.
Low corrosion inhibitors consumption allows extended drain intervals. Water pumps protection, avoid cavitation.
Seals, hoses, pipes and plastic parts friendly.

Contains a bitterness agent to prevent from drinking: coolants and antifreezes have a sweet taste but are harmful.

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.

PROPERTIES
Nitrite free, amine free, phosphate free, borate free, silicate free.
