Can a car run without engine oil?

Engine oil plays the role of lubrication, cooling and corrosion protection for automobile engines. If the engine has no oil, it can't be started, and forced starting will cause serious wear and tear on the inner wall.

If you find that the engine is leaking oil, you should reduce your driving and go to the 4S shop and repair shop for inspection as soon as possible when you are uncertain about the remaining oil. Because the working environment of engine oil is in the engine cylinder, and there is fuel in the engine cylinder, the internal temperature of the engine is very high, which leads to the high temperature of the engine piston. The cylinder is cooled by antifreeze, which can achieve good heat dissipation effect. But the piston can only rely on oil to dissipate heat. The kinetic energy of the engine is provided by the continuous operation of the piston. It is particularly important to ensure that the piston works normally under high temperature and high pressure. When the engine is running, it will continuously spray oil to the bottom of the piston to achieve the purpose of cooling. If there is no oil, it is difficult for the piston to dissipate heat, resulting in engine failure. In more serious cases, engine parts will deform or even soften and bite together because of high temperature, which will cause the car to break down. Low-level maintenance only requires replacement of parts, and serious maintenance will require replacement of the entire assembly.

So, you can prepare a liter of oil in the trunk of the car. If you find oil leakage, you can fill it up with engine oil and then drive it to a 4S shop or repair shop for maintenance.
