Is it necessary to warm up the car immediately after starting?
1 Answers
In theory, modern fuel-injected vehicles do not require warming up immediately after starting. However, since the engine oil lubrication is insufficient right after startup, which can cause greater wear to the engine, it is advisable to warm up the car to minimize damage to internal components. Below is more information about warming up the car: 1. Reasons for warming up: After the car has been parked for an extended period, the engine oil flows back into the oil pan at the bottom of the engine. Therefore, when starting the engine after prolonged disuse (such as overnight), the upper part of the engine is without oil and lacks lubrication. It takes about 10 seconds after starting for the oil pump to circulate the oil to critical components like the pistons, connecting rods, and crankshaft, where lubrication is most needed. At this point, the impact on internal components is minimal. 2. The correct method for warming up: After starting, wait 10 to 20 seconds before driving. During this period, avoid stomping on the accelerator and driving at high RPMs; instead, maintain a low speed with the engine RPM not exceeding 3000~3500.
