8109 GearOil TDL 75W90 GL-5

Versatil, all-season synthetic gear lubricant formulated with premium base oils and advanced additives to ensure maximum protection and performance. It delivers excellent low-temperature fluidity for reliable start-up lubrication and maintains a strong protective film under extreme heat and heavy loads. Suitable for synchronized manual transmissions, including heavy-duty units, as well as differentials with limited-slip (LS) systems, steering mechanisms, and other transmission components requiring API GL-4/GL-5 performance, it provides outstanding thermal stability, oxidation resistance, friction control, and superior wear protection under high-torque, low-speed conditions.
