The USD is a currency. Due to its stability, it is also used as a store of value by foreign countries.

Oil is pegged to the dollar. The price of oil is relevant because of its effects on prices, not the dollar.

Oil producers may target a dollar price and trade in dollars, but oil is not pegged (that is: trading with a fixed exchange rate) to the dollar.
