Why does an engine burn oil?

I am wanting to know how I can get my engine to burn oil. I want to see clouds of blue smoke pouring out from under my truck when I drive off. I have my pipes cut off and my catalytic converter doesn't really work, so there wont be any problems being able to see it. All I need to know is how to get the engine to burn oil. I have a 4.7L V8.Why does an engine burn oil?
Friction causing heat changes the molecular structure of the oil.Why does an engine burn oil?
beat on your truck until it is bagged and barely runs. so all the piston rings are worn and wrecked. like take off as fast as you can all the time. so your engine becomes worthless and can not successfully get anywhere without changing the spark plugs. and you will have the coolest blue smoke coming out!! it will be totally rad! yeah!
Drive it for about 200,000 miles until the valve guides wear out.
put some oil in the intake but not to much. that or add 2 stroke oil to the gas.
