A cold start is when the vehicle is started at a low engine temperature after being parked for a long time. At this time, the viscosity of the engine oil is high, the fluidity is poor, and the various parts of the engine cannot be lubricated in time, resulting in aggravated engine wear, reduced performance, increased fuel consumption, and even failure. Therefore, when the vehicle is cold started, it takes a certain amount of time for the oil to work in place to achieve the best lubrication effect.
So, how long does it take for the oil to work in place when the vehicle starts cold?There is no one set answer to this question, because different models, different oils, and different ambient temperatures will affect the fluidity and lubricity of the oil. Generally, it takes 3 to 5 minutes for the oil to work in place when a vehicle is cold started, but this is not absolute, and sometimes it may take longer or shorter.
So, what should we do when the vehicle starts cold?Many people believe that when a vehicle starts cold, it should first let the engine idle for a while and wait for the oil temperature to rise before driving. This approach is actually wrong, because idling not only does not effectively increase the oil temperature, but will increase the load and fuel consumption of the engine, and will also cause oxidation and carbon deposition of the oil, affecting the life of the engine.
The correct approach is to put the vehicle into gear immediately after the cold start, drive slowly, avoid sharp acceleration, sharp braking, sharp turning and other fierce operations, so that the engine and oil gradually heat up to achieve normal working conditions. In this way, not only the engine is protected, but also fuel consumption is saved and efficiency is increased.
In short, when the vehicle starts cold, it takes a certain amount of time for the oil to work in place, and this time varies from car to car, from oil to oil, and from temperature to temperature, and there is no unified standard. We should operate the vehicle reasonably according to the actual situation, let the engine and oil heat up gently, achieve the best lubrication effect, and ensure the performance and life of the vehicle.
