SAE J2360-2025 PDF

Full title and description

SAE J2360 — Automotive Gear Lubricants for Commercial and Military Use. This SAE technical standard specifies performance requirements, test methods and qualification information for automotive gear lubricants intended primarily for hypoid gear units (differentials and axles) operating under high‑speed/shock and low‑speed/high‑torque conditions; it also defines qualification procedures for listing on the gear lubricant Qualified Products List (QPL).

Abstract

J2360 defines minimum performance, additive and test requirements for gear lubricants that exceed API GL‑5 and are suitable for heavy automotive and military hypoid gear applications. The standard emphasizes extreme‑pressure (EP) protection, thermal/oxidation stability, seal compatibility and field performance; Appendix A and associated program documents (e.g., PD4000) are used to demonstrate compliance for QPL listing.

Scope

This standard applies to gear lubricants intended for automotive/hypoid gear units (primarily differentials and drive axles) that require extreme‑pressure protection under combinations of high speed/shock and low speed/high torque. It clarifies intended applications, exclusions (for example, not intended for worm gear lubrication), and the use of Appendix A and external qualification program documents (PD4000 / LRI) for QPL listing and field demonstration.

Key topics and requirements

• Minimum performance exceeding API GL‑5 for hypoid/auto axle service.
• Extreme‑pressure (EP) additive system and anti‑wear protection suitable for sliding contact of hypoid gears.
• Thermal and oxidative stability requirements and bench/field test protocols.
• Seal compatibility and formulation guidance to avoid degradation of elastomers.
• Qualification and listing procedures tied to Appendix A and the Lubricant Review Institute / PRI program (PD4000).

Typical use and users

Used by lubricant formulators, OEMs (automotive and heavy‑duty vehicle manufacturers), fleet maintainers, military procurement and qualification authorities, and testing laboratories that evaluate and qualify gear oils for axle/differential service and QPL listing. Procurement and specification teams reference J2360 when specifying high‑performance gear oils for commercial and military vehicles.

Related standards

Commonly cross‑referenced standards and specifications include API GL‑5 classifications, MIL‑PRF‑2105 series (historical military gear oil specifications), SAE J306 (SAE viscosity grades for gear oils), and OEM-specific approvals and test methods. J2360 is used alongside program documents such as PD4000 for QPL administration.

FAQ

Q: What is this standard?

A: SAE J2360 is an SAE technical standard that specifies performance and qualification requirements for automotive gear lubricants used in hypoid gear applications (commercial and military use). It sets test requirements and a qualification pathway for QPL listing.

Q: What does it cover?

A: It covers lubricant performance (EP/anti‑wear), viscosity and thermal behavior expectations, seal compatibility, required laboratory and field tests, and the process for demonstrating compliance for listing on the Qualified Products List (via Appendix A and PD4000). It is not intended for worm gears.

Q: Who typically uses it?

A: Lubricant manufacturers, OEM engineering and procurement teams, maintenance and fleet managers, military specifiers, and third‑party test laboratories involved in qualifying gear oils for axle and differential service.

Q: Is it current or superseded?

A: Current — the document was revised and published on December 17, 2025 (J2360_202512). Users should reference the 2025 revision for the latest requirements and QPL qualification procedures.

Q: Is it part of a series?

A: J2360 sits within SAE’s fuels & lubricants technical area and relates to other SAE lubrication and viscosity standards (for example J306 for gear oil viscosity grades) and to historical military and API gear oil specifications (e.g., MIL‑PRF‑2105, API GL‑5). It is used together with program documents (PD4000) for qualification.

Q: What are the key keywords?

A: Gear lubricant, hypoid, axle oil, extreme pressure, API GL‑5, seal compatibility, QPL, lubricant qualification, SAE J2360.
