At what percentage of car engine oil is it unsafe to drive?
1 Answers
It is unsafe to drive when the car engine oil level is below 25%. The reasons are as follows: 1. Insufficient engine oil: This can cause the engine to overheat and lead to wear. 2. Requirement: When the oil level is below 25%, it has already dropped below the minimum mark on the dipstick, making it unsafe to drive. 3. Component damage: Insufficient oil increases gear friction and heat, which can easily cause damage to the gearbox. Relevant information about engine oil is as follows: 1. Engine oil: It is the lubricating oil used by the engine, composed of base oil and additives. 2. Function: With a density of approximately 0.91×10³ (kg/m³), engine oil lubricates and reduces friction, assists in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption. It is known as the 'blood' of the car. Base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing new properties and serving as an important part of the lubricating oil.
