Can the engine start after adding oil following a shutdown due to lack of oil?

[OLiam]

After the engine shuts down due to lack of oil, it may not start normally even after adding oil. This is because the absence of oil leads to a loss of lubrication and cooling functions, causing significant damage to the internal components of the engine, such as cylinder scoring. Here are some relevant details: 1. Burning oil: "Burning oil" refers to the situation where oil enters the engine's combustion chamber and participates in combustion along with the air-fuel mixture. This phenomenon can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, insufficient lubrication can cause irreparable damage to the engine or even render it unusable, significantly increasing repair costs and posing potential safety hazards. 2. Causes of failure: Due to the disparity between domestic fuel quality and international standards, large amounts of carbon deposits can easily form in the combustion chamber during engine operation. These carbon deposits are the root cause of various engine problems. Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together and preventing them from sealing properly. The "stuck" piston rings greatly reduce their oil-scraping and sealing capabilities. Additionally, sludge can clog the oil return holes, preventing oil from returning normally and leading to increased oil consumption.
