When a friend buys a used car, he must have a certain understanding of all aspects of the vehicle and pick a good time to check the lubricating oil of the used vehicle. If there is a problem with the lubricating oil, it may mean that the vehicle is very problematic. Large, the following Xiaobian teach you how to check the location of lubricants. First, to observe the color of oil When we inspect the lubricating oil, prepare a piece of paper, then wipe the dipstick on the paper and observe the color of the lubricating oil. The color of a normally normal lubricating oil is transparent. If it is not transparent, it must be replaced in time. Generally high-viscosity lubricants are darker in color. If the oil is at a normal temperature, the viscosity of the oil is a little darker, which proves that the quality of the oil is not good. Lubrication slippage is generally oxidized during vehicle travel. Coupled with the wear of vehicle parts, air will enter the tank and cause the oil to darken. This is normal. If you find that the same color of lubrication changes greatly, such as turning gray or white, we must check the vehicle at this time. Generally, the following conditions will cause changes in oil quality. 1. After the oil enters the water, the lubrication of the engine oil is not good, and engine operation will be caused by long-term operation. 2. If there is an oil leak inside the engine, it will cause the engine's cooling to easily seep into the oil. 3. If the engine is poorly sealed, it will cause water infiltration Second, check the oil cover We must remove the fuel cap and observe its bottom. If there is a dark sticky material in the fuel cap. There is a small drop, indicating that this situation is not normal, a great reason may be the cylinder pad is broken. Once this happens, we must promptly inspect and repair the interior of the engine. Third, check the amount of lubricant Observe that the amount of oil is not normal. If the amount of oil is too small, the engine will be damaged. Valves and other parts will also be damaged. If there is time to look at the cylinder pressure is not normal.
