What are complementary goods to oil?

Complementary goods to oil include products that are typically consumed together with oil or whose demand increases with the use of oil. Some examples include gasoline, which is refined from crude oil, and products like diesel fuel, jet fuel, and heating oil. Additionally, goods like automobiles and machinery that rely on oil for operation can also be considered complementary goods. When oil prices rise, the demand for these complementary goods often correlates with that change.
