What is the symbol for no engine oil in a car?
2 Answers
When a car is low on engine oil, it will display an oil can dripping symbol. The engine oil indicator light is used to show the oil level and pressure condition inside the engine, and its color is mainly red or yellow. Here is some relevant information about engine oil: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives compensate for and improve any shortcomings in the base oil's performance, giving it new characteristics. Additives are an essential part of the lubricant.
I recently encountered a situation where the red oil can icon (resembling an oil droplet) on the dashboard lit up. This warning light demands immediate attention as it indicates either critically low oil pressure or insufficient engine oil. If ignored and driving continues, the engine's internal components may experience excessive friction and overheating – potentially causing cylinder scoring or complete engine seizure within just a few kilometers, leading to repair costs amounting to thousands.
Recommended action:
1. Safely pull over and shut off the engine immediately when the light appears
2. Check oil level on level ground with a cold engine:
- Wipe clean the dipstick, reinsert fully, then check if oil is below MIN mark
- If below MIN, add oil to reach the midpoint between MIN-MAX
- If empty or unsure, DO NOT drive – arrange towing to a repair shop
Prevention:
- Perform regular oil checks (every 5,000 km or monthly)
- Develop this maintenance habit to avoid roadside emergencies
