Le Chi's car ran out of engine oil, so he went directly to put out the fire. It didn't pull the cylinder. You can start it with engine oil, but the engine rattles.

Excuse me, is there any oil leakage in other parts of your engine? If there is no oil leakage, there will be no shortage of oil, unless it is burning oil, and your oil is dirty. If it is dirty, I suggest you change it. If there is enough oil, you can start the engine and open the oil cover to see if there is any oil flying to the rocker arm of the valve cover. If there is, there is no problem with the oil circuit. If there is, it is oil. I suggest you clean the throttle and idle motor, check the spark plug and a better fuel tank, so that it will be much better to speed up and save fuel.
