Does a car need to warm up before starting?
2 Answers
Yes, a car needs to warm up before starting. Reasons for warming up: After prolonged parking, most of the engine oil inside the car flows back to the oil pan. During a cold start, the oil cannot immediately reach all engine components to form an effective protective film on their surfaces. If the vehicle is driven immediately after starting, it will accelerate engine wear. Correct method for warming up a car: After starting the engine, wait for 30 seconds to 1 minute before driving, then proceed at a slow speed. Accelerate only after the temperature returns to normal. However, considering that components like the engine are still at low temperatures, avoid high engine RPMs during this period. Gently press the accelerator to keep the engine speed below 2000 RPM, operating under relatively 'gentle' conditions.
I've been driving for over a decade and have deep experience with warm-up issues. During cold starts, the lubricating oil between engine components hasn't fully circulated yet. Warming up for a few minutes allows for more even distribution and reduces wear. Long-term neglect of warm-up may lead to increased carbon buildup on piston rings and higher fuel consumption, which can be expensive to repair. Modern cars have more advanced fuel injection systems, but I still recommend waiting 30 seconds to 1 minute before moving off in winter. Avoid stomping on the accelerator and drive smoothly to protect engine lifespan. Remember that regular oil changes are also crucial - don't ignore the warm-up principles written in your new car's manual.
