Product labeling on the dispenser is intended to inform the consumer of what type of fuel and grade they are purchasing. Improper labeling or lack of labeling could confuse or mislead the consumer. For this reason federal and state regulations require specific dispenser labeling of the different products sold to the consumer.
Octane posting must be in accordance with the Federal Trade Commission’s Automotive Fuel Ratings, Certification and Posting Rule. Labels stating the minimum (R+M)/2 octane rating of the grade being dispensed shall be placed on the face of each dispenser as close to the calculating mechanism as practical and in a position clear and conspicuous from the drivers position. (Code of Federal Regulations 16 CFR Part 306)
Alcohol and Other Oxygenates
The requirement for alcohol and oxygenate labeling was discontinued effective September 10, 2002.
Since regular leaded gasoline is no longer in the marketplace, unleaded fuel containing a lead substitute additive, and having an octane rating (R+M)/2 of 88 may be sold. The dispenser shall be labeled as regular gasoline and a label stating the product contains a lead substitute additive shall be placed on the dispensers’ front panel in a position clear and conspicuous from the drivers’ position. No where on the pump shall it be stated that an unleaded product is being dispensed.
Lead Substitute Warning
Most lead substitute additives contain compounds that are detrimental to the vehicles emission control systems. Extreme care must be taken to avoid trace contamination with gasoline being sold as unleaded gasoline. Also, the dispenser’s nozzle shall not be the unleaded type.
Diesel fuel shall be identified by the grade of product being sold: No. 1-D or No. 2-D. The grade of product shall be posted in the upper fifty percent (50%) of the front panel in a position clear and conspicuous from the drivers’ position.
Kerosene offered for sale at retail shall be posted by grades of No. 1-K or No. 2-K. Grade No. 2-K offered for sale at retail shall also be posted conspicuously on the front of the dispensing device, the words "Warning - Not Suitable for use in Unvented Heaters Requiring No. 1-K".
Aviation gasoline shall be identified by grade of product: Grade 80, Grade 100, or Grade 100LL. Labeling should be in accordance with the most recent edition of National Fire Protection Association, NFPA 407, Standard for Aircraft Fuel Servicing.
Aviation Turbine Fuel shall be identified by Jet A, Jet A-1, or Jet B, in a position clear and conspicuous to the consumer. Labeling should be in accordance with the most recent edition of National Fire Protection Association, NFPA 407, Standard for Aircraft Fuel Servicing.
Often racing gasoline will not meet automotive gasoline requirements due to its low volatility. The low volatility is to satisfy the very high under-hood temperatures encountered in this class of service. If the fuel is properly identified as Racing Fuel and the proper octane rating (R+M)/2 is posted, special consideration will be allowed at the retail filling station. The Fuel Quality Program may request a specification product bulletin produced by the fuel manufacturer. If the fuel contains lead, the fuel cannot be sold for use in on-highway vehicles.
