Is Warm-up Necessary in Summer?

[HarmonyAnn]

Warm-up is necessary in summer because after prolonged parking, the engine oil flows back to the lower oil pan of the engine. Therefore, upon ignition, the upper part of the engine is in a state without oil and lacks lubrication. It takes about 30 seconds after starting for the oil pump to circulate the oil to the parts that need lubrication the most, such as pistons, connecting rods, and crankshafts. Pay attention to the following points during warm-up: 1. Avoid stomping on the accelerator during idle: It is best to drive smoothly at around 40 km/h for the first 2-4 kilometers. Otherwise, it will cause rapid wear and tear on the engine, severely damaging its components. 2. The coolant temperature should reach normal operating levels: When exiting an underground garage, you usually have to climb a steep slope. If the engine hasn't reached its normal operating temperature, forcing it will only result in greater wear and tear on the vehicle.
