What is the function of engine oil in a combustion engine?

The function of engine oil in a combustion engine is crucial for its efficient operation and longevity. The correct combination encompasses three main roles:

1. Wear protection: Engine oil creates a lubricating film that reduces friction between moving parts, thus preventing wear and tear, which is essential for maintaining engine health.

2. Cooling: As the engine operates, it generates heat. Engine oil helps absorb and dissipate this heat, preventing overheating and ensuring optimal operating temperatures.

3. Cleaning: Engine oil collects and suspends dirt, debris, and contaminants, helping to keep the engine clean and functioning effectively. This prevents buildup that could lead to engine damage.

In the context of German traffic regulations, maintaining your vehicle, including regular oil checks and changes, is crucial for road safety and compliance with vehicle operation standards. A well-lubricated engine reduces the risk of breakdowns and accidents resulting from mechanical failure. Understanding these functions emphasizes the importance of regular vehicle maintenance as mandated by regulations for ensuring safety on the roads.
