The oil of a car is just like human blood, and it is related to the health and life of the vehicle. How to identify whether the engine oil is deteriorating? Xiao Bian tells you four ways to teach you to tell if the oil is deteriorating. Manual method This is the simplest method. The old engine oil that is taken out is rubbed repeatedly with the thumb and index finger, and the good hand senses that it has lubricity, no wear debris, and no friction. If you feel a lot of friction between the fingers like sand, and poor adhesion, or even astringent, it shows that there are iron scraps, sludge and impurities in the oil, this oil landlord does not have to wait until when? Illumination Take out the dipstick 45 degrees, this is not to self-timer, the landlord do not misunderstand. It is to observe the oil droplets in the light, so that you can clearly see whether there are any debris in the oil droplets. In view of the landlord's IQ, I still have to say one more thing. The engine oil that is not worn at the end of the swarf is good, but if there is more at the end of the swarf, it will have to be replaced. Smell method Just saw it and I saw it. Should I smell it? General food deterioration will emit a sour smell, referral common sense landlord should know it? Pull out the oil dip stick to the nose and smell it. If there is a strong sour smell, what does this mean? Explain that the engine oil has deteriorated! Or a word: change! Color discrimination Here you need the landlord to prepare a clean white filter test paper, if not, with a little better make-up tissues also OK, what Jiehe ah heart is a good choice. Then the old engine oil was dribbled on the paper, and after the standby oil leaked, the engine oil of good quality was powder-free, and it was dry and smooth by hand, and the yellow infiltration zone was clear. If it is dark dark brown, it means there are impurities. Wuan Jianfeng Casting Co., Ltd. , https://www.hbjfcasting.com
