**Recommendation for 237-2**

**NIST Handbook 130: Engine Fuels, Petroleum Products, and Automotive
Lubricants Regulation**

Uniform Engine Fuels, Petroleum Products,

and Automotive Lubricants Regulation

as adopted by

The National Conference on Weights and Measures[^1]

**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.

> **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

> 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

> 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)
