146. Engine oil

Engine oil is a lubricant used inside an internal-combustion engine to reduce friction and wear between moving components. It also helps remove heat, keep internal surfaces clean and protect components against corrosion.

The oil level and condition should be checked according to the vehicle manufacturer's instructions. Only oil with the correct specification and viscosity should be used, and the oil and oil filter should be replaced at the recommended maintenance intervals.

What does engine oil do?

Engine oil lubricates moving components, reduces friction and wear, helps carry away heat and keeps contaminants suspended so that they can be removed by the oil filter or during an oil change.

How do you check the engine oil level?

Depending on the vehicle, the level is checked with an oil dipstick or an electronic oil-level system. The vehicle manufacturer's instructions should be followed because the required procedure can vary between engines.

Can you use any engine oil?

No. Engine oils have different viscosity grades and technical specifications. Only oil meeting the requirements specified by the vehicle manufacturer should be used.
