High every body . Recently I noticed that the level of engine oil is increasing with time , I just withdraw 500 ml of oil from engine before 1 week , now after 1 week again the level is above the upper limit with petrol smell inside... I'm really get terrible !!!
500 ml equals about 1/2 a quart. Could be an injector leak or leaks...What year/make/model/engine is this?
This is a most dangerous situation as if their is a missfire and the the fuel particles per million is just right...you would have an crankcase explosion which would eject the oil cap, dip stick and anything else....possibly killing you.
I would start by draiing the oil now and refill with fresh oil to dilute the gasoline contamination just for starters.

Easy test is get yourself a Fuel Pressure tester and hook it on the fuel rail of the engine. Start your engine - let it run for a minute. Shut it off and see if the gauge needle drops down....indicating an injector stuck open letting gas into the cyclinder. NOW if the gauge stays still. and steady....Then its not leaking. Suspect that the EVAP system is sucking in gas fumes but in my estimation..its fumes not liquid gas...unlikely situation.
Are there any demonstrate videos please
The fuel regulator is a MAJOR culprit as many posters have written here...this would be the first item to check out.

Sounds like you are running extremely RICH on startup and excess gasoline is not burning and washing past the piston rings. Need to have your cold start system checked.
Are you sure it's a 2008 Chevrolet Lumina? As far as I know 2001 was the last production year for the Lumina. It should have a 3.1 L V6 engine. With the engine running remove the vacuum hose from the fuel pressure regulator and see if fuel spits out of the fuel pressure regulator. Replace regulator if it does.
