Engine oil is UEFA live freethe "blood" of engine operation, and its quality directly affects the life and performance of the engine. Therefore, it is very important to check the quality of engine oil correctly. This article will introduce in detail how to check the quality of engine oil. I. Preparations before inspection 1. Turn off the engine: Check the engine oil quality when the engine is stopped and the oil temperature is normal to avoid burning hands. Two. Park on a flat ground: After the engine stops, the vehicle should be parked on a flat ground. This allows the oil to stay fully in the engine to ensure the accuracy of the measurement. 3. Operation time: It is best to check the engine oil after each refueling or full oil, so as to better grasp the oil situation.II. Step 1 to check the quality of engine oil. Open the hood and find the oil dipenser: The oil dip is generally located on the engine cover, and there is a scale indicating the lowest and highest oil levels. Two. Take out the oil gauge and wipe it clean: Before taking out the oil gauge, it must be wiped clean to avoid oil stains affecting the measurement results. 3. Insert the oil diper and take it out: Insert the oil diper and then take it out, and see if the oil reaches the scale position of the oil diper. Four. Judge the quality of the oil: (1) The color of the oil: Under normal circumstances, the oil color is brown or yellow, but if the oil is turbid, emulsified or blackened, it is necessary to consider replacing the oil. ( 2) Viscosity of the oil: scratch the oil with your finger to see if the oil is sticky. If the oil is not sticky enough, it means that the oil is too fluid and needs to be replaced or ionized.(3) The amount of oil: If the amount of oil is too small, it will lead to insufficient lubrication when driving, and too much oil will be compressed. When measuring, you should pay attention to whether the amount of oil is within a reasonable range. III. Precautions 1. Engine oil check should not be too frequent, otherwise it will lead to oil deterioration. Two. Before checking the engine oil, the engine must be stopped and cooled to avoid burning hands. 3. Before inserting the oil gauge, it must be wiped clean to avoid oil stains affecting the measurement results. Four. The oil will produce high temperature during operation. If the air entering the engine is insufficient, it will further affect the quality of the oil. Therefore, attention must be paid to maintaining air circulation in the engine. 5. When measuring engine oil, you need to compare several different vehicles. Each brand of car should have its own instruction manual, and you should find detailed instructions on measuring oil in these manuals.In summary, correctly checking the quality of engine oil can not only help us better understand the health of the engine, but also effectively extend the life of the engine. Therefore, in daily maintenance, we must carefully check the quality of engine oil to ensure that the engine runs smoothly and maintains good performance.
