Should the car be warmed up before extracting the engine oil?

It is necessary to warm up the car before changing the engine oil. Generally, the car should be warmed up for about 5 minutes before changing the oil, as this allows the old oil to drain more thoroughly. There are 4 key points to note when changing the engine oil: 1. Use dedicated engine oil: High-quality gasoline engine oil with the viscosity specified by the vehicle manufacturer should be used; 2. Add the appropriate amount of oil: After closing the engine oil filler cap, let the engine idle for 5 minutes before turning it off. Wait for 3 minutes, then pull out the dipstick to check if the oil level is within the normal range; 3. Post-change inspection: After completing the oil change, check for any leaks at the oil pan drain plug and the oil filter sealing interface; 4. Regular replacement: Engine oil must be changed according to the recommended replacement cycle.

I've been driving for over a decade and always warm up the car before an oil change. When the oil temperature rises, it thins out, making it easier to drain completely and reducing residue. I once tried draining cold oil, but it didn't come out cleanly, resulting in engine noise during operation—later found to be due to incomplete oil removal. Warming up for 5-10 minutes is sufficient; don't overdo it, as excessively high oil temperatures can scald your hands—wear gloves for protection. By the way, regular oil changes every 5,000 kilometers prevent carbon buildup and extend engine life. This habit keeps my car running efficiently, smooth, and fuel-efficient. Safety tip: Don't rush to work immediately after warming up; wait for the temperature to drop slightly before proceeding.

Warming up the engine before an oil change is a must! Hot oil flows better, making it quicker and cleaner to extract. When I do DIY maintenance at home, I always let the car run for a few minutes before draining the oil. Cold oil is too thick—it leaves residue even after prolonged draining, and the engine sound can get weird. After warming up, the oil pump works efficiently, finishing the job in minutes and saving time and effort. Don’t forget to check the dipstick to confirm the oil is fully drained. Safety first—don’t touch hot oil to avoid burns. After the oil change, the car runs smoother and even saves a bit on fuel. Beginners should start with a warm engine to avoid future hassles. Regular maintenance is crucial—check the oil condition every six months.

In car maintenance, warming up the engine before oil extraction is a recommended practice. Warm oil flows smoothly, allowing for more thorough extraction. Cold oil is viscous and tends to leave residual oil at the bottom, which can affect the performance of the new oil. Warming up the car for about 5 minutes until the oil reaches a moderate temperature is ideal for the operation. Be cautious of high temperatures during the process to avoid burns. Regular oil changes prevent carbon buildup in the engine and ensure smooth operation. If the engine is not warmed up, oil extraction may be incomplete, leading to performance degradation. This simple and practical habit is beneficial for the vehicle's health.
