Embodiment 1

[0009] The base oil of lubricating oil is synthetic fat and any mixed oil selected from API classification II, III and IV, and its weight percentage is 80-90%; add additives including: detergent, ashless dispersant, antioxidant Anti-corrosion and anti-rust agent, auxiliary antioxidant, viscosity index improver, pour point depressant, defoamer, friction modifier, extreme pressure agent and anti-friction and anti-wear synergist, the total additives account for 10-20% of the total weight of the composition %. Among them, the friction modifier is composed of sulfurized dihydrocarbyl dithiophosphate (S-MDTP) or dihydrocarbyl dithiophosphate (MDTP) and molybdenum dihydrocarbyl dithiocarbamate (MoDTC) with a hydrocarbon group of 2-ethylhexyl ) compound, its composite ratio is S-MDTP or MDTP:MoDTC=(1~4):(4~1), and its content accounts for 0.001~0.5% (by molybdenum weight) of the total composition; S- MDTP or the metal constituting the salt in MDTP is molybdenum (Mo) or tungsten (W). ...

Embodiment 2

[0011] Add the base oil into the blending kettle according to the metered quantity, start stirring, and raise the temperature to 65-70 degrees Celsius, and add the quantities of each component in Table-1 to the base oil in the following order, first add the pour point depressant, the second Add viscosity index improver first, then add auxiliary antioxidant, anti-oxidant and anti-corrosion agent, detergent, dispersant, defoamer, friction modifier compound, extreme pressure agent, anti-friction and anti-wear synergist in turn. After adding all the components, keep the original temperature and continue to stir for 30 minutes. After all the components are mixed evenly, cool down to room temperature to obtain a homogeneous, light brown, clear and transparent lubricating oil.

Description

technical field [0001] The invention belongs to lubricants, in particular to an energy-saving and environment-friendly lubricating oil. Background technique [0002] At present, due to the increase in the number of automobiles, work efficiency and living standards have been improved, but their energy consumption and exhaust emissions are also very alarming to the environment. Starting from the development of high-performance lubricating oil for internal combustion engines to reduce the frictional resistance of engine internal components and improve the dynamic sealing effect between pistons and cylinders will be an important way to reduce automobile energy consumption and environmental pollution. One of its measures is to add a friction modifier to the lubricating oil. The current level of automobile manufacturing has integrated the high-tech achievements of the 20th century. Automobile engines have achieved unprecedented high-speed, high-load and high-intensity operation. ...
