Einölen

Einölen is a German verb meaning to apply oil to a surface for lubrication, protection, or conditioning. The action is common in mechanical maintenance (such as bearings, gears, chains, or hinges), as well as in the care of wood and leather, where oiling helps reduce wear or restore appearance.

Grammar and usage: Einölen is a separable-prefix verb with the prefix ein- attached to ölen. In present tense, the prefix is separated and placed at the end of the clause, for example: Ich öle das Teil ein. In compound tenses, it behaves like other separable verbs and uses the appropriate auxiliary and past participle form according to standard German verb conjugation.

Contexts and nuances: In mechanical contexts, einölen aims to reduce friction, prevent rust, and extend component life. In woodworking, oiling surfaces can condition and enhance the finish, while in leather care, it helps maintain suppleness and protect against drying out. The term is formal enough for technical writing but may appear in everyday maintenance discussions as well.
