LIQUI MOLY Top Tec 5400 MTF 75W-90 Gear Oil for Porsche, Audi, Volkswagen, and Mini (1985–2024), 1 Liter

LIQUI MOLY Top Tec 5400 MTF is a 75W-90 gear oil, sold in a 1-liter bottle, for highly stressed manual transmissions, auxiliary drives, and differential gears in Porsche, Audi, Volkswagen, and Mini models. It carries API GL4 approval. LIQUI MOLY credits it with good viscosity and temperature behavior across a wide viscosity range, strong seal compatibility, resistance to aging, wear resistance, and high pressure-absorption capability. It also lowers gearshift resistance, reduces transmission noise, and protects against corrosion. The oil is made in Germany.

Gear oil in a differential keeps a lubricating film between the gear teeth and carries heat away from the bearings, so viscosity and specification both matter. LIQUI MOLY recommends Top Tec 5400 for vehicles that call for VW 501 50, VW G 005 000, VW G 052 145, VW G 052 157, VW G 052 190, VW G 052 911, VW G 50, and VW G 51. It cross-references the factory numbers G052145S2, G005000, G052157, G052190, G052911, G50, G51, and 50150, which is the quickest way to match it to the oil your owner's manual or service records call for. Because it is rated for both manual gearboxes and differentials, one product can cover both on cars that share a specification.

LIQUI MOLY was founded in Ulm, Germany, in 1957, when Hans Henle acquired the LIQUI MOLY name and a patent for a molybdenum disulfide oil additive. The company develops and produces its oils in Germany and tests every step from raw material delivery through production to shipping.
