How often should the turbocharger oil be changed?
For many car owners, there is a problem for everyone to struggle with. For turbocharger engines, should I change the oil frequently? Many car owners may have heard from 4S shops and repair shops that turbocharger engines have a shorter oil change time than naturally aspirated engines, but why do turbocharged engines need to change the oil frequently?
In fact, it’s very simple. The turbocharged engine has a greater workload. If you let the 1.5T engine do 2.0 work, can he not be tired? With higher pressure, the turbocharger is like a blower, forcibly pressing the air to the engine for combustion. indoor. Such high temperature and high pressure working conditions must have better lubrication conditions to ensure the normal operation of the turbocharger.
In order to make everyone understand it, let’s talk about the lubrication method of the turbocharger. To a certain extent, it proves that the turbocharged engine really needs to be diligent in replacing the oil filter. Otherwise, some cars may have to replace the turbocharger in advance.
In the turbocharger rotor part, the impellers on both sides are connected by an intermediate shaft. The intermediate shaft has a bearing and a lubrication hole on the bearing. The oil sent from the engine flows between the bearing and the intermediate shaft through the lubrication hole. The intermediate shaft is hundreds of thousands per minute. Turn, think about it, any impurities will definitely cause wear. And their working environment is more than 700 degrees, and they also need to rely on lubricating oil to cool down.
One of the main functions of engine oil is to clean and carry metal debris. If the oil has been used for a long time, it will carry more metal scraps and its fluidity will decrease. When such oil flows to the turbocharger, the flow rate is insufficient due to poor fluidity, which cannot meet the lubrication requirements and evaporates in large amounts. It also leaves the carried metal chips near the turbine bearings, resulting in insufficient lubrication of the turbine rotor bearings.
The turbocharger is almost unrecognizable because of the waste oil. If you are unlucky, the turbocharger of your car is likely to be damaged. The main reason for the damage is the ablation and seizure of the turbocharger rotor due to insufficient lubrication of the bearings. The only way to repair is to replace the supercharger assembly. So why do you need to change the oil filter frequently? Everyone knows it. In fact, the oil does not need to be changed too frequently, just follow the "doctor's advice" in the maintenance manual to change the appropriate oil.
The rotor shaft of the turbocharger is ablated or locked due to insufficient lubrication of the bearing, and it must be replaced or repaired. So what kind of turbocharger has repair value? Generally, original parts with a service life of less than 12 years are worth repairing. Repairing the turbocharger is only about one-third to one-fifth of the replacement part, which is still a good choice.
