Is it fuel injected? If so could be a faulty fuel injector. Letting fuel by while engine is off.

inspect each sparkplug for excessive fuel is one way. one or more injector(s) could be stuck open.

Best to let it sit for a while. Maybe over night then pull the plugs out to inspect. Do not start car before you check them cause that will cause the extra fuel to burn off and you won't be able to tell if the injectors are leaking. If they are wet with fuel then it's injector is stuck open. They should be good and dry.

What ever it is, be CAREFUL!!! Fuel in the oil can cause a fire in the crankcase, and that is guaranteed to kill the engine, and it can be extremely dangerous.
