Engine oil is added to an engine to decrease friction between moving parts. The oil forms a lubricating film between the surfaces, reducing wear and heat generation.
The sump is a tank (reservoir) at the bottom of the engine which contains lubricating oil. When the engine is switched off, the warm lubricating oil at the top of the engine, seeps back into the sump by gravity, ready for future lubricating use when the engine is running again.

it's lubricating properties
Lubricating oil allows for the metal parts of an engine to slide by each other without chipping away the two parts. Without it, the engine would start chipping away at each other and leave open areas, causing defficiencies and breaking on/of the engine
'Knocking' in petrol engines is caused by petrols low flashpoint - its high combustibility. The octane rating is too low for the compression.
A line diagram of the main lubricating system for a marine engine typically includes key components such as the oil sump, oil pump, oil cooler, and filters. The diagram illustrates the flow of lubricating oil from the sump through the pump, which circulates the oil to the engine's critical areas for lubrication. After passing through the engine, the oil is filtered and cooled before returning to the sump, ensuring efficient lubrication and temperature regulation. This closed-loop system is vital for maintaining engine performance and longevity.
engine oil is thick than hydraulic oil
Use exactly what the manufacture recommends any major brand.
No lubricating oils are not. The reason is that they have to be able to withstand heat from friction of moving engine parts etc. They have very high boiling points and thus very low volatility.
