In autumn and winter, the weather turns cool, ordinary lubricating oil will become thicker at low temperatures, and the fluidity will weaken, resulting in the vehicle is not easy to start and the wear will increase. Therefore, the owner of a tanker using ordinary lubricating oil must not forget to change the oil of the tanker.
Universal lubricants are
The lubricating oil should be selected according to the requirements of the engine, neither too much oil can be used on the engine with lower requirements, nor can the lower oil be used on the engine with higher requirements. The choice of lubricating oil can be upgraded on the basis of the manufacturer's recommendation, or the choice of synthetic oil has better performance.
In addition, there are now all-purpose motor oils on the market for winter and summer. No matter how the temperature changes, the general purpose oil can maintain a more stable lubrication performance, and play a better role in protecting the engine. Therefore, this oil is the choice.
If the engine is new or in good condition, low viscosity oil should be used as much as possible, such as 0W-40, 5W-40 and 10W-40, etc., to make the flow of lubricating oil faster and reduce wear when starting. If it is in the high temperature season or the engine has been worn to a certain extent, it is necessary to choose a high viscosity oil, such as 15W-50, which is conducive to the formation of a thick oil film, maintain the pressure of the oil, and reduce oil consumption.
Additives are not necessary in lubricating oil
Tank truck manufacturers remind that it is generally not recommended to add additives to lubricating oil. Because the components of the lubricant itself are composed of base oils and additives, its formulation has been tested and screened in a variety of ways. Adding additives may be counterproductive, not only reducing the original cleaning and anti-wear function of the lubricating oil, but also increasing sludge and carbon accumulation, affecting the performance and service life of the engine.
Tank truck manufacturers remind that at the same time of replacing lubricating oil, the lubricating oil filter element generally needs to be replaced, so that the newly replaced lubricating oil can play a better role. Lubricating oil products between different brands can not be mixed.
There's a way to tell the good from the bad
At present, there are many fake fish on the market, many tanker car owners can not identify the quality of lubricating oil, now teach you a few tricks. To observe. If the oil is clear and yellow-brown, it indicates that its quality is good; If the color is cloudy or emulsified, it means that there is much water; If the oil has a burning smell, it indicates premature oxidation or mixing with other oil products. Is to see if there is sediment, sediment is not a good oil. Third, the oil can be dropped on the iron plate or exhaust pipe above 110 ° C, such as the explosion sound, indicating that the oil contains water.
In fact, the way to insurance is to go to the designated dealer, big brand gas station or repair shop to buy oil or change oil.
