No precipitate is generated even after 4 weeks in the above cycle test, and good storage stability is obtained. Indicated. Although calcium phenate having a metal ratio of 1 was used as the component (B), no precipitate was formed, and good storage stability was exhibited.
- the lubricating oil additive and the lubricating oil composition of the present invention do not generate precipitates and are excellent in storage stability.
- Lubricating oil additives or lubricating oil products that used a combination of (per) basic salicylate and (neutral) sulfonate or other metal-based detergents that caused troubles even if distributed Products can now be supplied.
- the salicylate-containing lubricating oil and other metallic detergent-containing lubricating oil are mixed or mixed when the oil type in the storage tank is changed, it is possible to prevent problems from occurring. It has become possible.
- the lubricating oil additive and the lubricating oil composition of the present invention are excellent in high-temperature detergency and oxidative stability, and can be used as a mouth drain. It is possible to provide the desired performance. Therefore, the lubricating oil additive and the lubricating oil composition of the present invention are useful as a lubricating oil additive or as a lubricating oil thread and a gasoline engine for motorcycles, automobiles, power generation, ships, etc.
- lubricating oil additives and lubricating oil compositions for internal combustion engines such as diesel engines and gas engines, and in particular, because long drain performance can be further improved, low-sulfur fuels (for example, a sulfur content of 50 mass ppm or less, Or gasoline, light oil, natural gas, LPG, or hydrogen, dimethyl ether (DME), gas to liquid (GTL) fuel (gas oil fraction, gasoline fraction), alcohol containing less than 10 mass ppm
- low-sulfur fuels for example, a sulfur content of 50 mass ppm or less, Or gasoline, light oil, natural gas, LPG, or hydrogen, dimethyl ether (DME), gas to liquid (GTL) fuel (gas oil fraction, gasoline fraction), alcohol containing less than 10 mass ppm
- DME dimethyl ether
- GTL gas to liquid
- a lubricating oil additive for an internal combustion engine using the same a lubricating oil additive for an internal combustion engine using the same.
- the lubricating oil additive and the lubricating oil composition of the present invention can be used for lubricating oils that require improved storage stability, high-temperature detergency, and oxidation stability as described above, such as automatic or manual transmissions. It can be suitably used as a lubricating oil for drive train lubricating oil, grease, wet brake, hydraulic oil, turbine oil, compressor oil, bearing oil, refrigerating machine oil and the like and additives used therefor.
