Liqui Moly Motor Oil, Molygen, Top Tec & Additives for BMW, Audi, VW

What This Liqui Moly Collection Covers

Liqui Moly offers fluid and additive choices for routine service, high-mileage maintenance and performance-minded ownership. Start with the exact manufacturer approval, viscosity grade and system application, then select the proper fluid quantity for the service.

Motor Oil and OE Approvals

Top Tec, Molygen and Special Tec oils are designed around specific viscosity grades and manufacturer requirements. Check the owner manual, cap label and service documentation before selecting 0W-40, 5W-30, 5W-40 or another grade.

Transmission, Gear and Hydraulic Fluids

Automatic transmission fluid, manual transmission fluid and gear oil must match the transmission family and approval requirement. Using the correct fluid helps preserve shift behavior, friction characteristics and component life.

Fuel, Intake and Engine Additives

Cera Tec, MoS2 and Pro-Line products serve different maintenance goals. Use additives as directed and treat them as part of a complete service plan rather than a substitute for correcting mechanical faults.

Cooling, Grease and Service Chemicals

Coolant, brake-service products, greases and cleaners support the systems around the engine. Verify chemistry compatibility before mixing fluids and use the approved coolant for the vehicle application.

European, Import and Domestic Fitment

This collection includes products used across BMW, Audi, Volkswagen, Mercedes-Benz, Porsche, Japanese imports and domestic vehicles. Specification matching matters more than brand loyalty, especially for late-model turbocharged and direct-injection engines.

Common Questions

Which Liqui Moly motor oil is right for my vehicle?

Use the manufacturer-required viscosity and approval listed in the vehicle documentation, then choose the Liqui Moly formula that meets that requirement.

What is Molygen oil used for?

Molygen is a Liqui Moly motor-oil line intended for selected modern engines. Confirm the exact grade and approvals for the application.

Can I use Top Tec oil in BMW, Audi or VW applications?

Many Top Tec formulas target European approvals, but the exact product must match the engine and manufacturer specification.

Is Cera Tec a replacement for motor oil?

No, Cera Tec is a treatment product used according to its instructions and does not replace the correct engine oil.

How do I choose Liqui Moly transmission fluid?

Identify the transmission type and required factory fluid approval before selecting an automatic or manual transmission fluid.

Can I mix different coolant types?

Only mix coolant types when the vehicle manufacturer and product instructions confirm compatibility.

Do fuel additives fix mechanical problems?

Fuel additives can support maintenance but cannot repair worn injectors, failed sensors or mechanical faults.

How often should I change engine oil?

Follow the vehicle manufacturer service interval and shorten it when operating conditions or a performance build require more frequent service.

Does oil viscosity matter on turbocharged engines?

Yes, the correct viscosity and approval are important for lubrication, temperature control and turbocharger protection.

How do I order the correct Liqui Moly product?

Confirm vehicle year, engine, fuel type, service system and required approval before ordering.
