Here’s what Chatgpt pointed out:

✅ Why Driving Slowly Is Better:
• Faster warm-up: Driving gently warms up the engine more efficiently than idling because you’re putting the engine under light load, which increases operating temperature faster.
• Better oil circulation: At idle, oil moves more slowly, which can lead to less effective lubrication. Driving at low RPM helps circulate oil more evenly and quickly.
• Reduces wear and tear: Modern engines are designed to be driven (not idled) during warm-up. Long idling can lead to incomplete fuel combustion, which may cause carbon buildup over time.
• More fuel-efficient: Idling wastes fuel, especially in cold weather, where engines may idle longer than necessary.
⚠️ When to Idle Briefly:
• It’s fine to idle for 30–60 seconds in very cold weather (especially below freezing) just to ensure oil pressure stabilizes and defrosters start working.
• If your car has a turbo, letting it idle for a short time after starting and before shutting off can help protect the turbocharger.

Here’s what Hugo had to say:

If you live in Dubai there is no real need to warm up your engine. If it is the first ride of the day, wait for some seconds after firing up the engine and then drive normally. If this is not the first time you drove the car during the last twelve hours and -its not summer- you may have to wait for some more seconds till the engine idles after the initial start and start driving normally. In either scenario the engine oil should reach desired temperature pretty fast.

-Don’t idle your engine for long as many bad things may happen to the engine due to incomplete fuel compustion.

-Don’t idle your engine in indoors car parking spaces as this results in high CO2 emissions which is bad for humans.

-Don’t idle since that wastes fuel.

-Idling may damage the catalyst. Prolonged idling, especially in a vehicle with a rich air-fuel mixture or incomplete combustion, can lead to unburned fuel entering the catalytic converter

Autopolis Garage Co LLC and many modern automotive experts recommend not idling a cold engine. In fact, driving slowly is the best practice for both the health of the engine and for fuel efficiency.
