Full title and description

SAE J2785-2012 — Standardization of Color and Verbiage for Fuel Inlet Closures. This SAE Recommended Practice defines standardized colors and text/verbiage to be applied to fuel inlet (fuel filler) closures to identify fuel type and reduce the risk of misfueling in passenger cars, trucks and similar applications.

Abstract

SAE J2785-2012 specifies recommended colors and wording for fuel inlet closures for various automotive fuels. The practice provides a simple visual and textual identification method intended to prevent refueling mistakes that can damage engines and emissions systems. The document is concise (short recommended practice) and includes a table of specified colors and the recommended verbiage for each fuel type.

General information

• Status: Stabilized (no longer subject to periodic review).
• Publication date: May 31, 2012 (edition 2012).
• Publisher: SAE International (Society of Automotive Engineers).
• ICS / categories: Fuel systems; automotive fuel system practices (ICS reference commonly shown as 43.060.40).
• Edition / version: J2785-2012 (revises J2785-2006).
• Number of pages: 5 (short recommended practice document).

Scope

Applies to the standardization of color coding and short text/verbiage on fuel inlet (fuel filler) closures for different fuel types (gasoline, diesel, biofuels, alternative fuels where specified). The guidance is intended primarily for passenger cars and trucks but may be applied to marine, industrial, lawn-and-garden and other equipment where similar misfueling risks exist. The document points users to its color table (Section 4, Table 1) for the exact color specifications and the associated wording by fuel type.

Key topics and requirements

• Defined color specifications for fuel inlet closures by fuel type (see color table in the standard).
• Standardized short verbiage/text recommendations to be displayed on/near the fuel inlet (fuel type identification and cautions where applicable).
• Application guidance for passenger cars and trucks with optional applicability to marine and industrial equipment.
• Recommended practice (non-mandatory) intended to reduce misfueling and associated engine/emissions damage.
• Revision history: 2012 edition replaces the 2006 edition (J2785-2006).

Typical use and users

Original equipment manufacturers (OEMs), vehicle fuel-system designers, parts suppliers, aftermarket cap and closure manufacturers, service and maintenance organizations, fleet managers, and regulatory or standards bodies reference this recommended practice when specifying or verifying fuel inlet labeling and color coding to prevent misfueling.

FAQ

Q: What is this standard?

A: SAE J2785-2012 is an SAE Recommended Practice that standardizes the color and short verbal labeling for fuel inlet (fuel filler) closures to identify fuel types and reduce misfueling incidents.

Q: What does it cover?

A: It covers recommended colors and wording to be applied to fuel inlet closures for different fuels, plus guidance on the intended applications (primarily passenger cars and trucks, with possible wider applicability).

Q: Who typically uses it?

A: Vehicle OEMs, component suppliers (caps/closures), aftermarket manufacturers, fleet operators, service shops and standards/regulatory professionals use the practice when specifying or verifying fuel inlet identification to avoid refueling errors.

Q: Is it current or superseded?

A: The 2012 edition (published May 31, 2012) is listed as Stabilized; it replaces the 2006 edition (J2785-2006).
