Liqui Moly's high-pressure gear oil uses carefully-selected base oils and a special blend of additives for outstanding lubrication and protection. Ideal for all GL-1 or GL-4 uses (including spur gear, bevel gear and worm gear transmissions), this top-quality gear oil reduces wear and minimizes running noise on manual transmissions. Excellent temperature-viscosity behavior ensures reliability in even the coldest climates. This long-lasting gear oil resists aging and works well with sealing materials. No wonder it's the choice of so many major European automakers.
