(b) Certification of automotive fuel rating by distributor receiving and distributing automotive fuel with certified automotive fuel rating; use of automotive fuel rating for certification by distributorEach distributor who receives automotive fuel, the automotive fuel rating of which is certified to him under this section, and distributes such fuel in commerce to another person other than the ultimate purchaser shall certify to such other person the automotive fuel rating of such fuel consistent with—(1) the automotive fuel rating of such fuel certified to such distributor; or (2) if such distributor elects (at such time and in such manner as the Federal Trade Commission may, by rule, prescribe), the automotive fuel rating of such fuel determined by such distributor.
(c) Display of automotive fuel rating by automotive fuel retailer; use of automotive fuel rating for displayEach automotive fuel retailer shall display in a clear and conspicuous manner, at the point of sale to ultimate purchasers of automotive fuel, the automotive fuel rating of such automotive fuel, which automotive fuel rating shall be consistent with—(1) the automotive fuel rating of such automotive fuel certified to such retailer under subsection (a)(2) or (b); (2) if such automotive fuel retailer elects (at such time and in such manner as the Federal Trade Commission may, by rule, prescribe), the automotive fuel rating of such automotive fuel determined by such retailer for such automotive fuel; or (3) if such automotive fuel retailer is a refiner, the automotive fuel rating of such automotive fuel determined under subsection (a)(1).

(e) Representation of antiknock characteristics of automotive fuel by person distributing automotive fuel; use of automotive fuel rating in representationNo person who distributes automotive fuel in commerce may make any representation respecting the antiknock characteristics of such fuel unless such representation fairly discloses the automotive fuel rating of such fuel consistent with such fuel’s automotive fuel rating as certified to or determined by such person under the foregoing provisions of this section.
(f) Additional statutory considerations respecting certification, display, or representation of automotive fuel rating of automotive fuelFor purposes of this section, the automotive fuel rating of any automotive fuel shall be considered to be certified, displayed, or represented by any person consistent with the rating certified to, or determined by, such person—(1) in the case of automotive fuel which consists of a blend of two or more quantities of automotive fuel of differing automotive fuel ratings, only if the rating certified, displayed, or represented by such person is the average of the automotive fuel ratings of such quantities, weighted by volume; or (2) in the case of fuel which does not consist of such a blend, only if the automotive fuel rating such person certifies, displays, or represents is the same as the automotive fuel rating of such fuel certified to, or determined by, such person.
(g) Nonapplicability of statutory requirementsThe foregoing provisions of this section shall not apply—(1) to any representation (by display at the point of sale or by other means) of any characteristics of any automotive fuel other than its automotive fuel rating; or (2) to the identification of automotive fuel at the point of sale (or elsewhere) by the trademark, trade name, or other identifying symbol or mark used in connection with the sale of such fuel.
(h) Display or representation of automotive fuel requirement of motor vehicle not to create express or implied warranty under State or Federal law respecting knocking characteristics of automotive fuelAny display or representation, with respect to the automotive fuel requirement of any motor vehicle, required to be made under any rule prescribed under subsection (d) shall not create an express or implied warranty under State or Federal law that any automotive fuel the automotive fuel rating of which equals or exceeds such automotive fuel requirement—(1) may be used as a fuel in all motor vehicles of the same class as that motor vehicle without knocking; or (2) may be used as a fuel in such motor vehicle under all operating conditions without knocking.
