Keeping your car within proper operating temperatures is vital to both engine life and performance. That is why we recommend using antifreeze formulated for your car. Motul Inugel Optimal Ultra and Inugel Expert Ultra Antifreeze provide excellent heat dispersion and protection against corrosion consistenely through high temperatures. These properties do not deteriorate quickly over aging, which means longer overall life of the coolant systems and longer fluid change intervals.

Do not use pure product. Mix with distilled water according to the freezing protection chart.
