How Many Minutes Is the Most Correct for Warming Up the Car in Summer?
3 Answers
In summer, warming up the car only requires 10 to 30 seconds. Here are the reasons why warming up is necessary: 1. The upper part of the engine lacks oil and lubrication after prolonged parking: After the car has been parked for a long time, the engine oil flows back to the oil pan at the lower part of the engine. Therefore, when starting the engine after not using the car for a while (such as overnight), the upper part of the engine is in a state without oil and lacks lubrication. It takes about 10 seconds after starting for the oil pump to circulate the oil to the parts that need lubrication the most, such as the pistons, connecting rods, and crankshaft. 2. The fuel supply system is still at a low temperature and cannot effectively vaporize gasoline completely: Before the engine reaches its operating temperature (approximately between 90-110 degrees Celsius), the fuel supply system, due to its low temperature, cannot effectively vaporize gasoline completely. When gasoline is still in a 'wet' liquid state and not vaporized, it is difficult to ignite and start the engine.
I've been driving for over twenty years, and in summer, there's no need to wait several minutes to warm up the car. In fact, after starting the engine, just wait 10 seconds to half a minute to let the oil circulate, and then you can drive. Idling for too long is actually harmful, wasting fuel and causing the engine to overheat and accumulate carbon deposits. In summer, the high temperature ensures good oil fluidity, so the warm-up time is very short. My habit is to wait briefly after starting and then drive at low speed, avoiding heavy throttle, allowing the engine to warm up evenly while running. This not only protects the car and extends its lifespan but also saves fuel and ensures safety. During every maintenance check, inspect the oil condition to ensure the lubrication system is functioning properly, so the car won't have major issues.
As an environmental enthusiast, I never delay warming up my car in summer. I start driving after just about 10 seconds of idling. Keeping the engine running for several minutes to warm up is unnecessary and just wastes fuel while emitting exhaust gases, which is not eco-friendly. The engine warms up more efficiently while in motion, and the oil heats up quickly in summer, so a short warm-up period is sufficient. I recommend gently pressing the accelerator and driving slowly for a few minutes. This saves fuel, reduces pollution, and protects the engine from wear and tear. Developing good habits and not wasting time idling is safe and responsible—good for both your car and the planet.
