0W40 oil: characteristics and reviews

The weather can be unpredictable. Drivers of cars are increasingly faced with the need to fill in the engine oil of a universal type. It is intended for use in hot or cold periods. W40 . For the unit to work effectively both in frost and heat, 0 W40 oil is used.

This consumable is produced by many large companies. The presented standard has a number of special characteristics. What features the present oil has, it is necessary to consider in more detail.

general characteristics

предназначено для защиты мотора от истирания и преждевременного разрушения. Engine oil 0W40 is designed to protect the motor from abrasion and premature failure. It removes excess heat from the rubbing mechanisms. Also this product covers all metal surfaces with a thin film. It ensures a good sliding of the rubbing elements, prolonging their operation.

Also the presented materials protect the motor from corrosion formation. They remove carbon deposits, dirt and soot from the engine system. These particles are suspended in oil. Over time, they accumulate. Lubricant changes its color to a dark, dirty shade. In this case, a replacement must be made. Otherwise, the lubricant will no longer be able to retain the contaminants in itself. They will settle on metal surfaces, causing microscopic damage to the parts.

It is on the right choice of engine oil depends on easy starting of the engine in frosts, as well as the absence of overheating in the summer. Previously, manufacturers supplied the market with oils designed exclusively for the warm or cold season. Today, vehicle owners purchase universal products. They are designed for use in both heat and frost.

Suitable lubricants are used for each specific operating condition. On the correctness of their choice depends on the full operation of the motor, as well as its durability.

For the engine of your car, only use the oil recommended by the manufacturer. If you want to change the lubricant for another variety, you should choose a composition with a similar set of additives. The products of different manufacturers can conflict with each other. This causes a deviation in the motor.

Viscosity index

которого учитывают при выборе, является его класс вязкости. One of the most important indicators of 0W40 oil, the characteristics of which are taken into account when choosing, is its viscosity class. Most often this parameter is indicated in accordance with the SAE standard (Community of Automotive Engineers). It was this association that first proposed the classification of oils according to the viscosity class index. It allocates only 6 winter and 5 summer lubricants.

In accordance with this procedure, three types of viscosity are distinguished. There is winter, summer and multigrade oil. The first category has the letter "W" in its marking. The figure standing next to it indicates the permissible limit at which the product is operated.

Summer greases do not have letters in the marking. They have only a figure. It indicates the upper limit of viscosity. For universal compositions, the lower limit of viscosity is first indicated, and then the upper limit is indicated. достаточно текучее, что позволяет запускать мотор при очень низких температурах. Oil 0W40 is fairly fluid, which allows the engine to run at very low temperatures. Its upper limit of viscosity indicates the possibility of the engine running at high thermometer values.

In other words, the oil of the presented viscosity class is suitable for conditions of harsh winters and hot summers. For a hot southern climate, you need to purchase products with a high level of viscosity. This will keep the thin film of lubricant on the parts even in extreme heat.

Benefits

предназначено для использования в климатических условиях нашей страны. Motor oil 0W40, 5W40 is intended for use in the climatic conditions of our country. It can withstand severe frosts.
