The viscosity of the oil may not be heavy enough to protect the engine.
The engine Burn out
the motor gets lubricated.
Not very long at all. Without engine oil the engine will lock up and become unrepairable. You will have to purchase a new car of this happens.
crack the engine block and oil mixes with water or antifreeze.
too much oil in the engine will cause of airation and will create too much pressure to your engine and will damage the headgasket.
Oil leakage and loss of compression and power loss.
Nothing provided the engine is not started up. With no oil, a running engine would eventually seize up.
A typical car engine will be oil-starved and it will be destroyed by friction. The oil pump will not be able to pump oil to the engine unless the engine is designed with a dry sump like you'd find in racing cars and aerobatic airplanes.
The engine blows. Usually pistons shoot into the engine. In most cases the engine will have to be replaced.
It will seize - due lack of lubrication and coolant (one of the oil's uses)
It will continue to leak oil and if you do not add oil regularly it will eventually cause engine damage.
The pistons seize up and your engine is shot. Found that out the hard way when I was 16 lol ALWAYSSS make sure you have oil in the car cause that little read check engine light is serious about oil.
