In the daily maintenance of the car, the car lubricating oil undoubtedly plays a vital role. Not only does it lubricate precision components and reduce wear, it also effectively cools, cleans and seals the engine's internal environment. However, when many owners enjoy the smooth driving experience brought by lubricating oil, they often ignore a key issue - the shelf life of automotive lubricating oil. So, how long is the shelf life of automotive lubricating oil? This article will give you an in-depth analysis to help you maintain your car scientifically and extend the engine life.

Automobile lubricating oil

First of all, it needs to be clear that the shelf life of automotive lubricating oil is not static, it is affected by a variety of factors. In general, unopened lubricating oil, under suitable storage conditions (such as light, dry, moderate temperature), its shelf life can be as long as several years, depending on the product specification, but usually 3 to 5 years. However, once the oil is unsealed and added to the engine, its shelf life enters a whole new stage of calculation. But it is worth noting that this is only a reference range, the actual shelf life needs to be combined with the specific product instructions to judge.

Key factors affecting shelf life:

2, additive formula: Modern lubricants add a variety of functional additives to improve performance, but the stability of these additives will also affect the overall shelf life.

3, storage conditions: temperature, humidity, light and other environmental factors have a significant impact on the shelf life of lubricating oil. The ideal storage environment should be dark, dry, and at a moderate temperature.

Potential hazards of expired use:

Once the lubricating oil expires, its performance will be greatly reduced, which may lead to reduced lubrication effect, increased engine wear, increased fuel consumption, and even cause failure. Therefore, regular inspection and replacement of lubricating oil is the key to ensure the healthy operation of the engine.
