Which of the following is most likely to happen if you drive with insufficient engine oil?

Driving with insufficient engine oil can lead to significant damage to the engine. Engine oil serves as a critical lubricant, reducing friction between the moving parts of the engine and helping to dissipate heat. Without an adequate amount of oil, the metal components can grind against each other, leading to increased wear and tear. This overheating and friction can ultimately cause the engine to seize, which means that the engine could stop functioning altogether. Prolonged operation without sufficient oil can result in irreversible damage, often necessitating extensive and costly repairs or even complete engine replacement. Therefore, maintaining appropriate oil levels is essential for engine health and longevity.
