Four stroke engines such as lawn mowers etc need only straight fuel. Either leaded or unleaded (depending on age and availability). no oil or other mixing is required

Why 2 stroke engine want mixture of petrol and oil?
because, unlike a 4 stroke it doesn't have engine oil lubricating all the engine components, so in the fuel mixture there is oil mixed in to do this job, it is not as effective as the 4 stroke idea though.... which is usually why 2 stroke engines wear and tear more of time .
Can you put castrol grand prix 4-stroke motorcycle oil in a 2 stroke dirt bike?
No if it says 4 stroke or 4 cycle you can not put it in a 2 stroke or 2cycle engine.
The burning air-fuel mixture forces the piston down on what stroke?
Depends on if this engine is a 2 stroke, 4 stroke, or rotary engine. I assume you are referring to a 4 stroke as found in the vast majority of automobiles built today. The answer is, At the top of the compression stroke. The 4 strokes of a 4 cycle engine are:# intake/induction stroke # compression stroke # power stroke # exhaust strokeDepends on if this engine is a 2 stroke, 4 stroke, or rotary engine.

What will happen if you put 4 stroke gear oil in a 2 stroke engine?
Nothing at all!
Why does a 2 stroke engine need oil mixed in the gas?
Because of the way 2 stroke engines work. On a 4 stroke engine there are intake and exhaust valves in the head, and the crankcase is full of oil. On the intake stroke, the intake valve opens and the fuel-air mixture is sucked down into the cylinder. On a 2 stroke engine they put the fuel-air mixture into the crankcase. On the piston's down stroke, the bottom of the piston compresses the mixture. When the piston goes down far enough to open the inlet, the fuel-air mixture is squirted into the cylinder. If they put motor oil in the crankcase, you'd wind up squirting liquid oil into the cylinder. When the engine tried to "compress" the liquid oil, the incompressible liquid oil would break something.
How does a 4 stroke engine work?
As the name states there are 4 strokes in a 4 stroke engine. Intake, when the piston draws in air/Fuel mixture. Compression, when the intake valve closes and the piston moves to the top off the stroke. Power stroke, when the compressed mixture is ignited, forcing the piston down. Last the exhaust stroke when the piston starts moving up and expells the burnt gases.
What do you do if you put 2 stroke engine oil instead of 4 stroke engine oil in your scooter?
Drain it out and replace with proper oil
What happens if petrol mix with engine oil in a 4 stroke engine?
If petrol mixes with engine oil in a 4 stroke engine then the mixture becomes thick and its combustion will not be efficient. The exhaust will be smoky due to this incomplete combustion. also this will reduce engine efficiency.
