Sense: adjective/1
Oiled, oily, greasy, and lubricated all relate to the presence of oil, but each carries a different nuance. Oiled is the most neutral term — it simply means oil has been applied to a surface, usually deliberately (an oiled chopping board, an oiled chain). Oily is a broader word that can mean containing oil (oily fish), producing too much oil (oily skin), or simply looking or feeling like oil. Greasy has a distinctly negative feel: it suggests an unpleasant, dirty, or excessive layer of grease, often on food, skin, or tools. Lubricated is a more technical word used when oil or a similar substance is applied specifically to reduce friction between moving parts — you lubricate an engine bearing, but you would not normally say you lubricated a salad bowl. In short: choose oiled for intentional treatment, oily for natural oil content, greasy for unwanted or excessive oil, and lubricated for mechanical contexts.

Etymology
The word 'oiled' is formed by adding the past-tense suffix '-ed' to the verb 'oil'. The noun 'oil' entered English through Old French 'oile' from Latin 'oleum', meaning olive oil. The Latin word was borrowed from Greek 'elaion' (olive oil), which is related to 'elaia' (olive). The adjective use of 'oiled' (coated with oil) developed naturally from the verb's past participle. The informal sense 'drunk', first recorded in the early 20th century, comes from the idea that a person who has drunk a lot of alcohol feels as smooth and loose as a well-lubricated machine — though this is a folk image rather than a literal comparison.
