How motor oil works
Friction reduction
Without oil, the internal surfaces will heat up and melt due to friction, and this will lead to very rapid engine seizure. The oil forms a molecular barrier between moving parts that reduces friction while preventing wear and minimizing heat generation.
Cooling hot spots
The temperature inside the engine can exceed 1000°C. As it circulates, engine oil acts as a coolant and conducts heat from hot spots to the sump.
Cleaning the inside of the engine
High-quality oil washes away combustion products (mainly soot) from internal engine components, carries them to the oil filter and holds the smallest particles in suspension until they are washed away during an oil change.
Oil Handling
For safe oil handling and disposal of used oil, always:
- Avoid skin contact with used engine oil. Repeated or repeated contact may be harmful to your health.
- Dispose of used oil and empty oil containers only in designated areas. Find out where your nearest waste oil collection point is located. Dumping oil on the ground or down the drain is illegal and immoral.
