軟土の如く、本発明の組成物をエンジン油として用いれ
ば、エンジン各部の摩耗が少なく、またオイル消費量が
少なく、しかも燃費が著しく向上する。Like soft soil, if the composition of the present invention is used as an engine oil, there will be less wear on various parts of the engine, less oil consumption, and moreover, fuel efficiency will be significantly improved.
したがって、本発明の組成物はマルチグレードエンジン
油（ＳＡＥ粘度規格で５Ｗ／３０．１０Ｗ／３０．ＩＯ
Ｗ／４０等に合致）として有効であり、特に自動車、船
舶、自家発電等のディーゼルエンジン又はアルコール燃
料エンジンの潤滑油として、さらにはガソリンエンジン
の潤滑油として好適に利用できるものである。Therefore, the composition of the present invention has a multigrade engine oil (SAE viscosity standard of 5W/30.10W/30.IO).
It is effective as a lubricating oil for diesel engines or alcohol-fueled engines used in automobiles, ships, private power generators, etc., and can also be suitably used as a lubricating oil for gasoline engines.
