It is not necessary to warm up the car every time it starts. From the perspective of the engine, modern engines are all fuel-injected engines, which no longer require warming up. However, from the standpoint of car maintenance and extending the vehicle's lifespan, warming up the car appropriately can be beneficial. When a car is parked for an extended period, various fluids in the car flow to the oil pan due to gravity. If the car is driven immediately under these conditions, the lack of sufficient lubrication can cause significant wear and tear on various components. In winter, cold weather naturally reduces the fluidity of the engine oil. Driving immediately or turning on the air conditioning under these conditions can accelerate engine wear, which over time may shorten the engine's lifespan.

I've been driving for over twenty years, from the early carburetor cars to today's fuel-injected vehicles, and there have been many changes. In the past, older cars had to idle for a few minutes after starting to warm up the engine, or they would easily stall. But modern cars with electronic fuel systems are more advanced in design and don't require warming up every time they start. My habit is to start the car, fasten the seatbelt, adjust the seat, and then gently press the accelerator to drive off, but keeping the speed low for the first minute or two, around 20-30 km/h, to let the engine warm up naturally. Idling for too long reduces engine efficiency, wastes gasoline, and emits more exhaust, which is bad for the air. On cold days with fog or similar conditions, I might wait at most 10 seconds for the oil to circulate before driving off. In short, operating this way each time protects the car and saves both hassle and fuel.

Is it necessary to install an engine hood cover?

It is recommended to install an engine hood cover. On one hand, it helps maintain cleanliness in the engine compartment, and on the other hand, it protects some wiring harnesses inside the engine bay while also reducing noise generated during engine operation. When engine covers were first invented, their primary purpose was to ensure tidiness in the engine compartment, serving mainly an aesthetic function. Many car owners worry that installing an engine cover might affect the engine's heat dissipation, but in reality, it does not impact engine cooling. The performance of the engine is not directly related to whether an engine cover is installed.

Should You Shift Gear or Release the Handbrake First in an Automatic Transmission?

Automatic and manual transmissions follow the same starting sequence: you should shift into gear first and then release the handbrake. The primary reason for this is safety, as shifting into gear connects the power transmission path in the gearbox. When you first shift into gear, the transmission is in first gear, where the torque is at its highest. If the brake isn't properly engaged, the vehicle could suddenly lurch forward. Automatic transmissions can be categorized into CVT, AT, and dual-clutch types. CVT and AT transmissions use a torque converter to transfer engine power to the gearbox, while dual-clutch transmissions rely on friction plates similar to manual transmissions to transmit power.
