Oil count or uncountable
Countable nouns (also called count nouns) are nouns that can be counted (apple, orange) and can be therefore be pluralized (apples, oranges). Uncountable nouns (also known as non-count or mass nouns) are amounts of something, which we cannot count (gunpowder, rice). Uncountable nouns are nouns that come in a state or quantity that is impossible to count; liquids are uncountable, as are things that act like liquids (sand, air). Abstract ideas like creativity or courage are also uncountable. Uncountable nouns are always considered to be singular, and can stand alone or be used with some, any, a little, and much.
