Description of the Related Art Conventionally, lubricating oils have been used in internal combustion engines, drivetrain devices such as automatic transmissions, shock absorbers, power steering systems, gears, etc. in order to ensure smooth operation. In particular, lubricating oil for internal combustion engines (engine oil) mainly lubricates various sliding parts, such as piston rings and cylinder liners, bearings for crankshafts and connecting rods (connecting rods), valve trains including cams and valve lifters, etc. It functions to cool the engine, cleanly disperse combustion products, and prevent rust and corrosion. As described above, lubricating oils for internal combustion engines are required to have various performances, and in recent years, high performances have been required as the performances, output power, and operating conditions of internal combustion engines have become more severe. . Therefore,
In order to satisfy such required performance, the lubricating oil for internal combustion engine may be, for example, an antiwear agent, a metal detergent, an ashless dispersant,
Various additives such as antioxidants are blended. As a basic function of a lubricating oil for an internal combustion engine, it is important to operate the engine smoothly under all conditions to prevent wear and seizure. Most of the engine lubrication part is in a fluid lubrication state, but boundary lubrication is likely to occur at the valve operating system and the top and bottom dead center of the piston, and the wear prevention property under such boundary lubrication is generally zinc dithiophosphate ( ZnDTP)
And zinc dithiocarbamate (ZnDTC). By the way, in an internal combustion engine, energy loss is large in a friction portion where lubricating oil is involved.
As a measure to reduce friction loss and fuel consumption, a friction modifier (F
(M: Friction modifier), and lubricating oils in which various additives are combined are used (for example, Japanese Patent Publication No. 3-23595). Lubricating oils for internal combustion engines of automobiles are operated at various oil temperatures, rotational speeds, and loads. Therefore, in order to further improve fuel consumption, it is necessary to have excellent friction characteristics under a wide range of use conditions. Ordinary fuel-efficient engine oils include ZnDTP and ZnDTC as antiwear agents, and molybdenum-based FM agents such as sulfurized oxymolybdenum dithiocarbamate (MoDTC) and ashless FM agents as friction modifiers. Are known. However, if an antiwear agent and a friction modifier are used together, competitive adsorption on the metal surface leads to an unfavorable situation in which the functions of both are not fully exhibited. That is, ZnDTP and ZnDTC prevent wear due to metal-metal contact by forming a protective film on the metal surface, but the friction modifier also adsorbs to the metal surface and reacts with it, or generates polymer on the metal surface. Forms a low-friction surface coating, and exerts the effect of reducing friction. Therefore, ZnDTP or ZnDTC should be used as the lubricating oil.
And a friction modifier are added, the amount of ZnDTP or ZnDTC adsorbed on the metal surface decreases due to competitive adsorption, and wear resistance deteriorates. In some cases, the effect of reducing friction is not obtained. Further, ZnDTP is an excellent anti-wear agent, but since it has the effect of roughening the friction surface,
It has the drawback of reducing the effect of the friction modifier. On the other hand, it is known that a complex of ZnDTP and an alkanolamine is superior to ZnDTP in abrasion resistance and friction reducing property (Japanese Patent Laid-Open No. 60-144394).

0.05 to 2 mol, preferably 0.1 to 1 mol of P
A range of 1.5 mol is desirable. The complex has a slight excess of unreacted ZnDT in order to enhance its solubility in the lubricating base oil.
Advantageously, it contains P. On the contrary, if the alkanolamine is contained in excess, this alkanolamine precipitates, which is not preferable. However, if the amount of alkanolamine used is less than 0.05 mol, the amount of free ZnDTP is too large,
It is not preferable because the abrasion resistance and the frictional properties become insufficient.
Examples of the diluent include mineral oil such as kerosene and light oil having a boiling point within the boiling range of the lubricating oil or lower, or diethyl ether. Although the use of such a diluent is not essential, it is preferable to use an appropriate amount of the diluent because the solution becomes highly viscous as the complex is formed.

１表に示す。EXAMPLES The present invention will be described in more detail by way of examples, which should not be construed as limiting the invention thereto. The wear scar diameter, friction coefficient, and upper sphere surface average roughness were determined as follows. (1) Shell four-ball test, rotation speed 1800 rpm, load 20 kgf, oil temperature 90 ° C., time 3
A shell four-ball test was performed under the condition of 0 minutes, and the wear scar diameter, the friction coefficient, and the upper sphere surface average roughness were obtained. (2) LFW-1 friction test Using the tester shown in FIG. 1, the rotation speed was 350 rpm and the oil temperature was 6
Falex R-type block (iron) and Fall under conditions of 5 ° C and 120 ° C, load of 90 kgf, and time of 3 minutes.
LFW using S-10 test ring (made by iron) manufactured by x company
A -1 friction test was conducted. In FIG. 1, 1 is an S-10 test ring, 2 is an R-type block, and 3 is a strain gauge. A load is applied to the R-shaped block and the resistance generated when the ring is rotated is detected by a strain gauge to calculate the friction coefficient.
The test oil is immersed in about half of the ring. In addition, ZnDTP / alkanolamine complex is ZnDT
It was prepared by mixing 0.1 part by weight of alkanolamine with 1 part by weight of P and heating with stirring at about 100 ° C. for 5 minutes. Examples 1 to 4, Comparative Examples 1 to 8 Mineral oil base oil (100 SN), addition components of the types and amounts shown in Table 1, and polymethacrylate-based viscosity index improver 4.0
A lubricating oil composition containing 1% by weight and 3.0% by weight of a succinimide ashless detergent dispersant was prepared, and a shell four-ball test and an LFW-1 test were conducted to determine the characteristics. The results are shown in Table 1.
