A vehicle engine must always have sufficient lubrication. The protective lubricating film reduces the mechanical friction of the moving components and prevents metal from making contact with metal. Without oil, the engine would suffer serious damage within seconds. The correct motor oil must guarantee lubrication under all operating conditions and loads that occur in the engine. It should have the lowest possible viscosity in the extreme cold to facilitate starting and to reach all the important lubrication points in the engine as quickly as possible. At extremely high temperatures, on the other hand, the lubricating film must not rupture as this would destroy the engine.
The motor oil’s most important task is the lubrication of the mechanical engine components. It is intended to reduce the friction between the moving components, thereby reducing wear to a minimum. The formation of a closed lubricating film is necessary to prevent engine damage due to metal-on-metal contact.
Every engine is different and therefore has different demands for the oil. When using the incorrect oil with the incorrect viscosity, the correct oil pressure cannot be built up which leads to engine damage. Additional negative consequences include loss of warranty, increasing fuel consumption, increased risk of breakdown, shorter engine service life and the destruction of the particulate filter and the catalytic converter.
What oil should be used when changing the oil? There are numerous suppliers with both cheap and expensive products. Naturally you wish to spend as little money as possible, leading you to purchase the cheap oil. This can end up costing you much more, however. The reason: The cheap oil does not meet all the manufacturer specifications and has lower performance reserves. It is therefore consumed more quickly and must be changed more frequently. High quality LIQUI MOLY motor oil, on the other hand, frequently exceeds the manufacturer specifications and extends the engine’s service life
Additives in the oil
The motor oil contains an individual additive package depending on the manufacturer specification. It is important that you use suitable oil for your vehicle as every engine has different demands for this.
