Oil coast the tip of the spark plug and creates an alternate path to ground the cylinder wall, there is no spark, resulting in a misfire condition. How quickly the plug fouls again depends on how severely the rings/valve guides/valve seals are worn. This happens because your engine doesn’t ignite the fuel in the cylinder on each combustion cycle. I have a car that sputters on idle and during low acceleration, then clears up somewhat when floored after it has warmed up. If motor runs smoothly again, just check oil consumption in the future.
