Eurol SAE80W90 HPG Gear Oil Eurol HPG Gear Oil is a transmission oil based on the latest phosphorus-sulfur technology. This additive technology protects the transmission against metal-to-metal contact under the most severe conditions, even with heavy shock loads. Eurol HPG Gear Oil contains additives that leave a thin film layer on surfaces, thereby preventing corrosion. In addition, the 80W-90 and 85W-140 grades have good fluidity at low temperatures, ensuring optimal oil performance in all seasons. Eurol HPG Gear Oil has excellent oxidation and aging stability and does not affect seals. Eurol HPG Gear Oil is recommended for hypoid gears, hub reductions, transfer cases, gearboxes, power take-offs and differentials where API GL-5, MIL-L 2105D and Mack GO-G are recommended, while the 85W-90 can also be used where MB 235.0 is prescribed.
