How many kilometers can a car run without engine oil?
2 Answers
Under the conditions of 70～90km/h, it can safely travel up to 120km at most. The following are the specific details: 1. Case: While starting the car engine, drain all the engine oil inside the car, and then use a hair dryer to blow away the residual oil on the engine and oil circuit. After adding Mo'an metal friction reduction and repair agent, the car without oil lubrication safely traveled 120km under the condition of 70～90km/h. Throughout the journey, the vehicle had no abnormal noise, and the engine worked normally. 2. Engine oil: Engine oil refers to the lubricating oil specially used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. Although a car without engine oil can run, exceeding a certain distance will increase the wear and tear of the car and may also cause traffic accidents. Therefore, regular oil changes are very important for cars.
I've been in the auto repair business for over a decade and have witnessed many car owners taking chances by driving without engine oil, only to have their engines fail within just a few kilometers. Engine oil serves the crucial functions of lubrication and cooling. Without it, the high-speed friction inside the engine causes temperatures to skyrocket. On the highway, the engine could seize and suffer damage in just a few minutes—sometimes not even making it two kilometers. In city driving, you might stretch it to five kilometers at most, but the risks are enormous. Don't believe the nonsense online about being able to drive dozens of kilometers without oil—the reality is that repairs will cost you a fortune. Develop the good habit of checking your oil level every month, and top it up promptly if it's low. Safety is more important than anything else.
