You generally do not need to wait long for a petrol car to warm up. Modern petrol engines are designed to reach optimal operating temperatures quickly. **It is typically sufficient to let the engine idle for about 30 seconds to one minute before driving.** This allows the oil to circulate adequately without wasting fuel or producing unnecessary emissions from extended idling.

Driving gently after a brief idle period will warm the engine more efficiently compared to prolonged idling. In extreme cold conditions, a slightly longer wait may be advisable, but even then, it's often best to start driving gently rather than allowing the engine to idle for long periods.
