According to the American Petroleum Institute (API), a standard barrel of oil is the amount of oil that would occupy a volume of exactly 1 barrel (158.99 L) at reference temperature and pressure conditions of 60 °F (15.6 °C) and 14.696 psi (1,013.25 hPa) (or 1 atm). This standard barrel of oil will occupy a different volume at different ...
Starting in January 2017, gasoline has been limited to an annual average of 10 ppm sulfur, with a maximum of 80 ppm allowed per batch at the refinery gate and up to 95 ppm downstream. [16] At this point, nearly all road and industrial fuels produced in the US have been substantially desulfurized to levels of 15 parts per million or less.
