                                In 2023, U.S. refineries produced about 45 gallons of products for every 42-gallon barrel of crude oil they processed, a phenomenon known as processing gain. This fact helps illustrate what does crude percentage mean, which is the quantifiable outcome of refining raw petroleum into marketable products.
