How motor oil works
Friction reduction
Without lubrication, the rubbing surfaces in the engine will heat up, melt and quickly render the engine unusable. The oil and its special additives form a molecular layer that separates the rubbing surfaces, preventing them from wearing out and generating heat.
Hot zone cooling
The oil cools the surfaces of the engine that the coolant cannot reach, such as the walls of the pistons and cylinders. where the temperature can exceed 1000°C. The oil helps transfer this heat to the cooling system. The heat of the oil is also carried away by air currents in the crankcase and. in some cases, an oil cooler.
Cleaning the inside of the engine
The oil washes away combustion products from the inner walls of the cylinders (mostly soot) and takes them to the filter. Only the smallest particles remain in the oil until it is changed.
Oil is harmful - remember this
When handling engine oil, always remember that:
- Do not allow engine oil to come into contact with skin. Prolonged skin contact with engine oil can be harmful to health.
- Collect the used oil in a container and take it to the nearest car dealership for recycling. Never pour oil on the ground.
