Can I add engine oil right after turning off the car?

You can add engine oil right after turning off the car because the oil flows better when the engine is warm, making it easier to add. Here are 4 key points to note when adding engine oil: 1. Choose oil based on the engine's requirements: Do not use high-grade oil in a low-performance engine or low-grade oil in a high-performance engine. Always select oil that matches the engine specifications. 2. Opt for multi-grade oil, which offers advantages like fuel efficiency and longer service life, providing better engine protection. 3. The oil level should be slightly below the mark on the dipstick—do not overfill. Excess oil increases crankshaft resistance, reduces engine power output, and may even enter the combustion chamber, leading to oil burning, blue smoke emissions, and increased fuel consumption. 4. Select oil viscosity based on engine condition and seasonal temperature: Use lower-viscosity oil if the engine is in good condition and the temperature is low; choose higher-viscosity oil if the engine is severely worn and the temperature is high.
