Can a vehicle run without engine oil?
2 Answers
Without engine oil, a vehicle cannot operate. The method for adding engine oil is as follows: 1. Lift the vehicle, remove the protective plate, and place a container capable of holding about 10 liters beneath the oil drain plug. 2. Loosen the oil drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the drain plug after the oil has completely drained and wipe it with a tissue to check for leaks. 3. Reinstall the protective plate, lower the vehicle, and use a funnel to add engine oil through the filler port. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts, thereby reducing wear. 2. To carry heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. 3. To circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away contaminants generated on the working surfaces of the parts through the flow of the lubricating oil.
I've driven many cars and often get asked whether an engine can run without oil. Oil is as vital to an engine as blood is to the heart—it lubricates metal components like pistons and bearings. Without oil, these parts grind directly against each other, generating extreme heat within minutes that can melt and fuse the metal together, completely destroying the engine. I've seen numerous cases where drivers ignored the oil warning light, stubbornly drove a few hundred meters, only to have the engine seize with strange noises, forcing them to spend a fortune replacing the entire unit. Modern technology has advanced, with sensors now alerting drivers, but never gamble on this. If there's no oil, it's best not to start the engine—immediately check the dipstick or call for a tow truck. Otherwise, trying to save a little could cost you thousands in repairs.
