N.C. Gen. Stat. § 119-27
In the event that the Gasoline and Oil Inspection Board shall adopt standards for grades of gasoline, at all times there shall be firmly attached to or painted on each dispensing pump or other dispensing device used in the retailing of gasoline a label stating that the gasoline contained therein is North Carolina ______ grade. Any person, firm, partnership, or corporation who shall offer or expose for sale gasoline from any dispensing pump or other dispensing device which has not been labeled as required by this section, and/or offer and expose for sale any gasoline which does not meet the required standard for the grade indicated on the label attached to the dispensing pump or other dispensing device, shall be guilty of a Class 2 misdemeanor, and the gasoline offered or exposed for sale shall be confiscated.
The gasoline and oil inspectors shall have the authority to immediately seize and seal, to prevent further sales, any dispensing pump or other dispensing device from which gasoline is offered or exposed for sale in violation of or without complying with the provisions of this Article. Provided, however, that this section shall not be construed to permit the destruction of any gasoline which may be blended or rerefined or offered for sale as complying with the legal specifications of a lower grade except under order of the court in which an indictment is brought for violation of the provisions of this Article. Provided, further, that gasoline that has been confiscated and sealed by the gasoline and oil inspectors for violation of the provisions of this Article shall not be offered or exposed for sale until the Director of the Gasoline and Oil Inspection Division has been fully satisfied that the gasoline offered or exposed for sale has been blended or rerefined or properly labeled to meet the requirements of this Article and the owners of said gasoline have been notified in writing of this fact by said Director and, provided, further, that the permitting of blending, rerefining or properly labeling of confiscated gasoline shall not be construed to in any manner affect any indictment which may be brought for violation of this section.
