Truck Gear Oil HC (GL4) 75W-80

Efficient high-pressure transmission oil for use in manual transmissions under heavy loads (with and without retarders or intarders), plus auxiliary transmissions. The high-quality basic oils (based on HC synthesis technology) and modern additive technology ensure a wide range of applications and optimal transmission lubrication under extreme conditions and at long oil change intervals (up to 320,000 km). Thanks to its low-friction characteristics, this oil can also be used in the event of transmission problems (e.g. stiff gear change) where high-viscosity/single-grade API GL4 oils are used, for example.
