LIQUI MOLY
LIQUI MOLY — Premium German Synthetic Oils, Additives & Specialty Lubricants
LIQUI MOLY has been engineering premium lubricants and additives in Germany since 1957, building a global reputation on product quality, technical depth, and consistent performance across a wide range of engine types and operating conditions. From full synthetic motor oils and gear lubricants to fuel system cleaners and specialty additives, LIQUI MOLY produces a comprehensive lineup of products trusted by OEM manufacturers, professional racing teams, and performance enthusiasts who demand more from their engine protection than a commodity oil can deliver.
Synthetic Motor Oils
LIQUI MOLY's motor oil lineup spans conventional, synthetic blend, and full synthetic formulations across a wide range of viscosity grades to match the specific requirements of modern and classic engines. The Molygen New Generation series uses a friction-reducing molybdenum compound that forms a protective layer on metal surfaces, reducing wear during cold starts and sustained high-load operation. The Top Tec series covers OEM-specification oils for European and Asian vehicles with specific manufacturer approvals — including BMW Longlife, Mercedes-Benz, Volkswagen, and Porsche specifications.
For high-performance and racing applications, LIQUI MOLY's Racing series oils are formulated for the elevated operating temperatures, high shear rates, and extended drain intervals demanded by built engines, forced induction applications, and track use. The Racing High Tech motor oil maintains viscosity stability under sustained high-RPM and high-temperature conditions where conventional synthetic oils thin out and lose film strength.
Gear Oils & Transmission Fluids
LIQUI MOLY produces gear oils for manual transmissions, differentials, and transfer cases across a range of viscosity grades and additive packages. The Hypoid Gear Oil series covers conventional and limited-slip differential applications, with friction modifier content matched to the specific clutch pack requirements of LSD units. Transmission fluids for automatic and dual-clutch transmissions are available with OEM-specification approvals for applications where fluid specification directly affects shift quality and transmission longevity.
Fuel System Additives & Engine Treatments
LIQUI MOLY's additive lineup is one of the most comprehensive in the industry, covering fuel system cleaning, oil system treatment, engine flush, and specialty protection products. The Jectron fuel system cleaner removes deposits from injectors, intake valves, and combustion chambers — restoring fuel atomization and combustion efficiency on engines with accumulated carbon buildup. The Pro-Line Engine Flush cleans oil passages and removes sludge before an oil change, ensuring the fresh oil goes into a clean system rather than mixing with degraded residue.
MoS2 anti-friction engine treatment adds a molybdenum disulfide layer to engine internals, reducing friction and wear during the critical break-in period of rebuilt engines and providing ongoing protection in high-mileage applications where metal-to-metal contact is more likely due to worn clearances.
Common Applications
LIQUI MOLY products cover domestic and import vehicles across all engine types — gasoline, diesel, turbocharged, naturally aspirated, and hybrid applications. European vehicle owners benefit particularly from LIQUI MOLY's extensive OEM approval coverage for BMW, Mercedes-Benz, Audi, Volkswagen, Porsche, and other manufacturers with specific oil specification requirements. Performance and racing applications are served by the Racing series and specialty additive lineup.
German Engineering & Quality Standards
Every LIQUI MOLY product is developed and manufactured in Ulm, Germany, with quality control processes that meet or exceed the requirements of the OEM approvals the products carry. LIQUI MOLY has been awarded the top position in German consumer oil quality surveys for over a decade — a reflection of consistent product performance across a wide range of real-world applications and operating conditions.
Installation Notes
LIQUI MOLY motor oils are direct replacements for OEM-specified oils in the correct viscosity grade and specification. Additives should be used according to the dosage instructions on each product — overuse of oil additives can affect viscosity and additive package balance in the base oil. Engine flush products are added to the old oil before draining and run for a short idle period — do not drive the vehicle with engine flush in the oil system.
