Motul Inugel Optimal Ultra (concentrate)

  • MOTUL INUGEL OPTIMAL ULTRA is a concentrated antifreeze that should be mixed with soft water for immediate use as a 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


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


  • Do not use pure product. Mix with soft water according to the required freezing protection: refer to chart
  • To maintain anti-corrosion properties, do not dilute below 33%.
  • Water for dilution: If possible use soft water: Maximum hardness 35°F and chlorides and sulfates maximum contain 500 ppm.
  • 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.
