As the economy continues to evolve, the actual demand for lubricants in the industry is on the rise because of its outstanding performance and popularity in most industries. In routine car maintenance, friends often encounter such problems as: After the opening of the oil is not used up, how to save it? Here to listen to industry experts for your specific introduction.

After unsealing, the remaining lubricating oil, if not properly stored, can cause deterioration. The cause of deterioration is mainly due to contact of the product with moisture, oxygen and impurities in the air. When the water content exceeds 0.1%, the additives (antioxidants, detergent and so on) in the product will fail, which will cause the acid oxides in the exhaust gas of the engine to react with water and generate the inorganic acid. These acidic substances increase the corrosion of the engine.

According to industry experts, the same, if contact with oxygen, it will have a chemical reaction, especially in the sunshine environment, leading to deterioration of additives, greatly reducing the oil oxidation resistance, cleaning and other characteristics.

After opening, the preservation of oil:

1, sealed immediately after opening

In the 4S shop or repair shop maintenance is completed, the lubricant cap should be immediately screwed. It should be noted that, Suzhou oil as the original tin foil film has been damaged, the rest of the cover pad isolated limited role, this time you can use a layer of clean plastic film sets in the bottle. In order to avoid damage to the best fold a few times after the set, and then screw the bottle cap, so the sealing effect is better. Conditions can also be drip wax seal at the bottle cap.

2, cool, dry place

After sealing it needs to be stored in a cool and dry place, and to ensure that will not be exposed to the sun, to avoid the bottle inside the product oxidation reaction.

3, use again, do not completely into it

In general, the bottom of the bottle stored for a long time will be a slight amount of water, added to the engine will affect its performance play or even have an adverse effect, so the next maintenance, remove the long-stored product, do not be all Into, should be retained part.
