What is the minimum oil level for a car?

The oil dipstick has two marking lines at its front end, and the oil level should not fall below the lower marking line. Insufficient oil can lead to cylinder scoring, poor lubrication, and increased component wear, while excessive oil can increase operational resistance. Additional information: 1. Excessive oil increases the operational resistance of the car, leading to adverse effects such as sluggish performance, muffled operation, and increased noise. 2. Excessive oil is more prone to temperature rise during operation, making it deteriorate faster and reducing its protective performance. 3. Excessive oil can create bubbles during component operation, which, when entering the lubrication or hydraulic systems, can increase wear and reduce performance. 4. During engine operation, the crankshaft and connecting rod ends generate intense agitation, not only increasing internal power loss but also causing more oil to splash onto the cylinder walls, leading to oil burning and exhaust faults.
When it comes to engine oil, the level must never drop below the MIN mark on the dipstick—that's the minimum safe oil level. I remember once driving on the highway when my car suddenly started shaking violently. After pulling over, I checked and found the oil level was below MIN, nearly causing engine failure. When oil levels are too low, the oil pump can't draw enough oil, leading to insufficient lubrication. Metal parts then rub dry, generating heat—this can accelerate wear in mild cases or even seize pistons, requiring major repairs. As an experienced driver with years on the road, I check the oil level monthly. Always inspect the dipstick when the engine is cold to ensure it's between MIN and MAX. If it's low, promptly top it up with the right oil to the midpoint. Don't underestimate this simple habit—it prevents unexpected breakdowns and costly repairs.
