What are the signs of severe engine oil shortage in a car?

The first sign of insufficient engine oil is the illumination of the oil warning light on the dashboard. This is a common warning signal in all vehicles when oil levels are low. Typically, it appears immediately after starting the vehicle because the oil pressure sensor detects low oil pressure due to insufficient oil, triggering the oil fault light. Additionally, in some mid-to-high-end models, text or graphic alerts may accompany the oil light. Below are additional details: 1. The second sign of low engine oil: unusual engine noises, often loud. This occurs because the lack of oil lubrication prevents the formation of a protective oil film on engine components, leading to metal-on-metal contact and resulting in abnormal sounds. If you are attentive to your vehicle, these noises can be heard within minutes of starting the engine. However, if you are less observant of the engine's condition, it may take some driving time to notice. 2. The third sign of insufficient engine oil: high oil temperature. For models without an oil temperature gauge, a warning may be issued through the illumination of the coolant temperature light.
As a seasoned driver with years of experience, I've encountered several instances of severe oil shortage. The most obvious precursor is the engine starting to produce abnormal knocking sounds, resembling metal hitting metal, which occurs due to increased friction from insufficient lubrication, typically becoming louder during acceleration or uphill driving. Another critical signal is the sudden illumination of the oil pressure warning light on the dashboard, alerting you to check the oil level. I've also noticed blue smoke from the exhaust, indicating oil leakage or burning, accompanied by a noticeable drop in power, with the accelerator feeling sluggish. Long-term neglect of these symptoms significantly increases the risk of engine overheating. I once experienced the light coming on and loud noises during high-speed driving, only to find the oil nearly depleted upon inspection, prompting an immediate top-up to avoid major repairs. I recommend checking the dipstick monthly when the engine is cold; the oil level should be between the min and max marks. Developing a habit of regular maintenance can save both hassle and money.
After I got my first car replaced last time, I encountered a severe oil shortage issue just a few days into driving it. The warning signs included suddenly louder engine noises, especially when starting from a red light—it felt like a drum was banging inside. Then the oil pressure light came on, which scared me into checking the cause immediately. I noticed some blue smoke coming from the exhaust, and the power dropped significantly. I later learned that this was due to insufficient oil causing increased friction and even spiking fuel consumption. That time, I dragged it to the repair shop and almost ruined the engine. Now, I make it a habit to check the dipstick after every car wash to avoid similar shocks. Remember not to check when the engine is hot—wait until it cools down before inserting the dipstick for an accurate reading. Such simple precautions can prevent major problems.
I enjoy tinkering with cars in my spare time and know the serious warning signs of low engine oil. First, the oil pressure light comes on—that dashboard indicator is very noticeable. Second, the engine noise increases, sounding like a ticking noise, which indicates insufficient lubrication and part wear. If blue smoke comes from the exhaust, it means oil is being burned, and you might also smell a burnt odor inside the car. Reduced power or engine shaking is also common due to poor engine performance. I recommend checking the dipstick weekly to ensure the oil level isn’t low, which can help prevent the risk of major engine repairs.
