Tasks of the motor oil
Why does the engine oil need to be changed?
Motor oil consumes and contaminates itself over time. For example, due to combustion in the engine, dilution with fuel or condensation, natural oil aging and mechanical abrasion.
Only a regular oil change, i.e. replacing the old, used oil with new oil, ensures reliable engine function and increases the service life of the engine.
The perfect oil change consists of:
- Motor flush
- Oil change
- Wear protection additive
All dirt and deposits inside the engine are removed by flushing the engine with Motor Clean before the oil change. The used oil is then completely removed from the oil circuit by draining. Because only in a clean engine can the fresh motor oil achieve its full performance. The engine then runs even more effectively, quieter and is more economical in consumption.
To ensure optimum long-lasting protection, we recommend adding the wear protection additive Cera Tec to the fresh engine oil when changing the oil. Thanks to the smooth-running effect, it also reduces friction, wear and fuel consumption and thus also increases the service life of the engine.
Our modern engine oils are both high-quality and officially approved by many manufacturers. Often, they even exceed the manufacturer’s specifications.
