Oil is used to lubricate the engine and some is splashed on the cylinder wall and pistions to lubricate those also!
But while that is happening, some oil gets past the pistons and into the combustion chamber were is is burnt along with the fuel.
Only a minute quantity is lost, but the more you run your car, the more oil gets lost, so you have to top-up the oil before it gets to the empty level.
Also, black soot from the burnt fuel get past the pistons in the opposite direction, which is why new oil changes from being yellow in colour to black.

Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke engine
What is better a four or two stroke engine?
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
Which engine was invented first.Two stroke engine or four stroke?
two stroke
What makes a two stroke engine produce twice as much power as a four stroke?
A 2-stroke engine makes power every2 cycles were a 4-stroke makes power every 4.Hence 2x power. This is absolutely INCORRECT! A two stroke engine develops it's PEAK horse power twice as fast as a four stroke for the reason given but that is it. For a given displacement a four stroke engine will ALWAYS make more torque and horsepower than a two stroke engine of equal displacement. This is due to the fact that a four stroke engine cleans the cylinder of contaminated (exhaust) air, compresses the air/fuel to a more efficient level, and draws a cleaner air/fuel mixture into the cylinder as there is no slow burning, air/fuel mixture contaminating oil mixed in the combustion charge. I have over forty years experience working on engines, and can tell you, the ONLY reason two stroke engines have lasted this long, is due to the fact that they weigh less than an equivalent horsepower four stroke engine. If they DID develop more horsepower, the four stroke would not have become the standard internal combustion engine used in transportation, generators, air compressors and the like.
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
Why do Car Engines have a four stroke engine?
Well since you may get stuck in traffic and 2 stroke motors are air cooled plus more emissions burning oil with gas
Compare the two stroke and four stroke engine in powe output and thermal efficiency?
compare the two stroke and four stroke engine in power output and thermal efficiency?
What is the second stroke called?
In a four-stroke engine its called the compression stroke
What statement correctly describes a four-stroke engine?
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
What are the four strokes to a four stroke engine?
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
Will four stroke oil damage two stroke engine?
You can use four stroke oil for a (very) limited period in a two stroke engine in an emergency. However it is not formulated for two stroke engines and is not recommended.
Is fuel for a two stroke engine fatal to a four stroke engine?
No it isn't fatal, but it would smoke quite a bit, because a two stroke engine needs two stroke oil mixed in the petrol, and a four stroke just needs petrol.
