MOTUL AUTO COOL G13 ULTRA is a concentrated long-life antifreeze designed to be combined with soft water for instant use as a cooling fluid. It relies on a combination of monoethylene glycol and glycerol, employing a hybrid organic/non-organic mix additive technology known as Lobrid Tech. This formulation comes highly recommended for the cooling systems of VAG group (VOLKSWAGEN, AUDI, SKODA, and SEAT) passenger cars and light-duty vehicles, particularly when a coolant that meets G13 standard requirements (VW TL 774 J) is needed.
