The specific conditions of the vehicle and the use environment select the appropriate viscosity grade lubricating oil

The choice of diesel engine lubricants for heavy-duty vehicles, heavy-duty vehicle diesel engine lubricants* The main thing is to choose the appropriate lubricant model, including viscosity grade and quality grade. Automotive technology and materials Diesel engine lubricants can be divided into single-grade oils and multi-grade oils according to their viscosity standards. Oils that can meet the viscosity standards of high or low temperature single performance are called single-grade oils, and oils that can meet both high and low temperature performance standards are called single-grade oils. Multi-grade oil, multi-grade oil is generally represented by two grade numbers in winter and summer. Since single-grade oils must be replaced with different viscosity grades in winter and summer, it is very troublesome, while multi-grade oils have a large temperature range and can be used throughout the year. Although the price is relatively high, it is convenient to use and eliminates the need for replacement. The trouble of oil has become a mainstream product in the diesel engine lubricant market. Due to the different ambient temperature ranges suitable for the use of multi-grade oils of different viscosity grades, the applicable ambient temperature ranges of the most commonly used multi-grade oils for diesel engines are given, and users can choose them reasonably according to specific conditions.

The choice of gear lubricants for heavy-duty vehicles The choice of gear lubricants for heavy-duty vehicles should be considered from two aspects: according to the specific conditions of the vehicle used and the environment of use, the appropriate viscosity grade lubricant should be selected; the choice should be based on the load of the vehicle used Lubricants of suitable quality grade. The table shows the viscosity classification of automotive gear oils, the applicable ambient temperature range of gear oils of various viscosity grades, and the quality classification of automotive gear oils. The user can select the appropriate gear lubricant according to the specific conditions of the vehicle used in conjunction with the data and instructions given in the table’.

is suitable for light-duty to medium-duty diesel engines and light-duty gasoline engines. Because high-quality combustion is the prerequisite for use, it requires bearing corrosion resistance and high-temperature deposition performance. It does not require wear resistance and deposition prevention. It is suitable for light-duty to medium-duty diesel engines. It is required to prevent wear and deposition during low-temperature combustion. At the same time, it is required to prevent bearing corrosion and high-temperature deposition when using high-sulfur fuel. It is suitable for light-duty turbocharged diesel engines. Moderate operation and excessive operation, also suitable for high-load gasoline engines. It is required to have anti-high temperature deposition, anti-low temperature deposition and anti-corrosion properties. It is used to prevent high-speed wear and deposition of supercharged diesel engines during high-speed and high-horsepower operation. Supercharged diesel engines can use various quality fuels and require bearing corrosion and high temperature deposition resistance.
