**Recommendation for 237-2**

**Information Item**

**Uniform Engine Fuels, Petroleum Products, and Automotive Lubricants
Regulation**

as adopted by

The National Conference on Weights and Measures\*

**1. Background**

In 1984, the National Conference on Weights and Measures adopted section
2.20. in the Uniform Regulation for the Method of Sale of Com­modities
requiring motor fuel con­taining alcohol be labeled as such to disclose
that information to the retail purchaser. The delegates deemed this
action necessary since motor vehicle manufac­turers were qualify­ing their
warranties with respect to some gasoline-alcohol blends, motor fuel
users were complaining to weights and measures officials about fuel
quality and vehicle performance, and the American Society for Testing
and Materials (ASTM) had not yet finalized quality standards for
oxy­genated (which includes alcohol-containing) fuels. While many argued
that weights and measures officials should not cross the line from
quantity assurance programs to programs regulating quality, the
delegates were persuaded that the issue needed im­mediate attention.

A Motor Fuels Task Force was appointed in 1984 to develop mechanisms for
achieving uniformity in the evalu­ation and regu­lation of motor fuels.

The Task Force developed the Uniform Motor Fuel Inspection Law (see the
Uniform Laws section of this Handbook) and the Uniform Motor Fuel
Regulation to accompany the Law.

The recommended Law required registration and certification of motor
fuel as meeting ASTM standards. The regulation defined the ASTM
standards to be applied to motor fuel.

In 1992 the NCWM established the Petroleum Subcommittee under the Laws
and Regulations Committee. The subcommittee recommended major revisions
to the Regulation that was adopted at the 80th NCWM in 1995. The scope
of the regulation was expanded to include all engine fuels, petroleum
products, and automotive lubricants; its title was changed accordingly;
and the fuel specifications and method of sale sections were revised to
address the additional products. Other changes included expansion of the
definitions section and addition of sections on retail storage tanks,
condemned product, registration of engine fuels designed for special
use, and test methods and reproducibility limits.

**2. Status of Promulgation**

The Uniform Regulation for Engine Fuels, Petroleum Products, and
Automotive Lubricants was adopted by the Conference in 1995. The sta­tus
of State actions with respect to this Regulation is shown in the table
beginning on page 8.

\*The National Conference on Weight sand Measures is sponsored by the
National Institute of Standards and Technology in partial implementation
of its statutory responsibility for "cooperation with the States in
securing uniformity in weights and measures laws and methods of
inspection."

ethanol; liquefied petroleum (LP) gases; compressed natural gas;
liquefied natural gas; biodiesel; diesel fuel; kerosene; aviation
gasoline; aviation turbine fuels; or, fuel oils are sold, an invoice,
bill of lading, shipping paper or other documentation, must accompany
each delivery other than a retail sale. This document must identify the
quantity, the name of the product, the particular grade of the product,
the applicable automotive fuel rating, and oxygenate type and content
(if applicable), the name and address of the seller and buyer, and the
date and time of the sale. Documentation must be retained at the retail
establishment for a period not less than 1 year.

**3.1.2. Retail Dispenser Labeling.** \-- All retail dispensing devices
must identify conspicuously the type of product, the particular grade of
the product, and the applicable automotive fuel rating.

**3.1.3. Grade Name.** \-- The sale of any product under any grade name
that indicates to the purchaser that it is of a certain automotive fuel
rating or ASTM grade shall not be permitted unless the automotive fuel
rating or grade indicated in the grade name is consistent with the value
and meets the requirements of Section 2, Standard Fuel Specifications.

**3.2. Automotive Gasoline and Automotive Gasoline-Oxygenate Blends**

**3.2.1.** **Posting of Antiknock Index Required.** \-- All automotive
gasoline and automotive gasoline-oxygenate blends shall post the
antiknock index in accordance with applicable regulations, 16 CFR Part
306 issued pursuant to the Petroleum Marketing Practices Act, as
amended.

**3.2.2.** **When the Term \"Leaded\" May Be Used.** \-- The term
\"leaded\" shall only be used when the fuel meets specification
requirements of paragraph 2.1.5.

**3.2.3.** **Use of Lead Substitute Must Be Disclosed.** \-- Each
dispensing device from which gasoline or gasoline oxygenate blend
containing a lead substitute is dispensed shall display the following
legend: \"Contains Lead Substitute.\" The lettering of this legend shall
not be less than 12 millimeters (1/2 in) in height and the color of the
lettering shall be in definite contrast to the background color to which
it is applied.

**3.2.4.** **Nozzle Requirements for Leaded Fuel.** \-- Each dispensing
device from which gasoline or gasoline-oxygenate blends that contains
lead in amounts sufficient to be considered \"leaded\" gasoline, or lead
substitute engine fuel, is sold shall be equipped with a nozzle spout
having a terminal end with an outside diameter of not less than 23.63
millimeters (0.930 in).

**3.2.5.** **Prohibition of Terms.** \-- It is prohibited to use
specific terms to describe a grade of gasoline or gasoline-oxygenate
blend unless it meets the minimum antiknock index requirement shown in
Table 1.

**3.2.6. Method of Retail Sale.** \-- **Type of Oxygenate Must be
Disclosed.** \-- All automotive gasoline or automotive
gasoline-oxygenate blends kept, offered, or exposed for sale, or sold,
at retail containing at least 1.5 mass percent oxygen shall be
identified as "with" or "containing" (or similar wording) the
predominant oxygenate in the engine fuel. For example, the label may
read "contains ethanol" or "with MTBE." The oxygenate contributing the
largest mass percent oxygen to the blend shall be considered the
predominant oxygenate. Where mixtures of only ethers are present, the
retailer may post the predominant oxygenate followed by the phrase "or
other ethers" or alternatively post the phrase "contains MTBE or other
ethers." In addition, gasoline-methanol blend fuels containing more than
0.15 mass percent oxygen from methanol shall be identified as "with" or
"containing" methanol. This information shall be posted on the upper 50
percent of the dispenser front panel in a position clear and conspicuous
from the driver's position in a type at least 12.7 mm (2 in) in height,
1.5 mm (1/16 in) stroke (width of type).

(Amended 1996)

**3.2.7. Documentation for Dispenser Labeling Purposes.** \-- The
retailer shall be provided, at the time of delivery of the fuel, on an
invoice, bill of lading, shipping paper, or other documentation, a
declaration of the predominant oxygenate or combination of oxygenates
present in concentrations sufficient to yield an oxygen content of at
least 1.5 mass percent in the fuel. Where mixtures of only ethers are
present, the fuel supplier may identify either the predominant oxygenate
in the fuel (i.e., the oxygenate contributing the largest mass percent
oxygen) or, alternatively, use the phrase "contains MTBE or other
ethers." In addition, any gasoline containing more than 0.15 mass
percent oxygen from methanol shall be identified as "with" or
"containing" methanol. This documentation is only for dispenser labeling
purposes; it is the responsibility of any potential blender to determine
the total oxygen content of the engine fuel before blending. (Amended
1996)

**3.3. Diesel Fuel**

**3.3.1.** **Labeling of Grade Required.** \-- Diesel Fuel shall be
