Do Sedans Need to Warm Up?

1 Answers
DeLily
07/30/25 7:24am
Sedans do need to warm up, requiring idling for about one minute before driving slowly at low speeds. The reasons are as follows: 1. At the moment of ignition: The upper part of the engine is in a state without oil and lacks lubrication. It takes about 30 seconds after starting the engine for the oil pump to deliver oil to components such as the pistons, connecting rods, and crankshaft. 2. After starting the vehicle: If the idle lubrication oil is not adequately supplied, it can easily lead to wear. Most wear on engine components occurs within the first three minutes after a cold start. After sitting overnight, the lubricating oil on the friction surfaces of the engine has mostly dissipated, losing the protective oil film.

Does a Newly Purchased Car Need a Break-in Period?

Newly purchased cars do require a break-in period, which typically ranges from 1,000 to 1,500 kilometers. This ensures that mechanical components fully contact, frictionally adapt, and settle into their proper positions. Break-in requirements include: 1. Maintain smooth starts, avoid sudden acceleration, and keep engine RPM below 3,000; 2. Ensure coolant temperature reaches at least 50°C before starting, begin in low gear, shift to higher gear after 1 km, and maintain coolant temperature between 80-90°C while driving; 3. Shift gears promptly during operation, avoid prolonged use of a single gear, and refrain from using high gears at low speeds or low gears at high speeds; 4. Avoid overloading the vehicle - lighter loads are better during break-in as excessive weight can cause damage; 5. Choose good road surfaces to minimize excessive vibration, impacts, or emergency braking, use high-quality fuel and engine oil, and avoid engine wear additives; 6. Prevent excessively long driving sessions.
