Whether you have a classic car or a new vehicle: The choice of the right motor oil is an important decision, after all, it is the “lifeblood” of the vehicle. This is especially true with German vehicles. German manufacturer requirements are demanding. With LIQUI MOLY products you always have peace of mind.

The capacity of oils is set out in the “API classifications” (American Petroleum Institute), as well as the “ACEA specifications” (Association des Constructeurs Europ. de l‘Automobile). The classification takes place using standardized engine tests in the test laboratory.

This is not enough for German car manufacturers such as Audi or Volkswagen. They have even tougher requirements.

These are set out in approvals (e.g. MB 229.5, Porsche A40 or BMW Longlife -01). After all, modern motor oils are high-tech products specially designed for certain car models – essentially tailor-made replacement parts. That’s why car manufacturers only give their approval to selected oils.

The wrong oil can in many cases even lead to carbonization and engine failure. An oil with reduced HTHS viscosity and minimal viscosity can be ideal for vehicle A, yet “lethal” to the engine in vehicle B! If you use the wrong oil, turbo engines also react sensitively, as the turbo charger requires extremely heat-stable lubricants. And in diesels with particulate filters the wrong oil can block the filter.
