ENEOS Automatic Transmission Fluid

ENEOS Automatic Transmission Fluid: OEM-Grade Protection for Modern Transmissions

ENEOS brings its decades of OEM partnership experience directly to the aftermarket through a focused lineup of automatic transmission fluids engineered to meet the exacting demands of today's multi-speed and slip-lockup transmissions. As Japan's largest oil company — established in 1888 and headquartered in Tokyo, with manufacturing and sales facilities throughout the world — ENEOS occupies a uniquely authoritative position in the ATF category: it has worked with Japan's automakers and leading race teams for decades, and has developed engine and transmission oils for the majority of car manufacturers throughout Japan and Asia.

Two Approaches to ATF: Multi-Vehicle and OE-Specific

ENEOS structures its ATF lineup around two philosophies. The first is broad compatibility. The flagship ECO-ATF PLUS is the go-to choice for owners who need one fluid to cover many vehicles: it is a fuel-efficient, low-viscosity automatic transmission fluid that meets the specs of over 86% of automatic transmissions in the marketplace. ECO-ATF PLUS provides improved fuel economy, high resistance to mechanical shear and fatigue, and wide-ranging compatibility with Asian OEMs, Dexron® VI, Mercon® LV, and other American and European vehicle specifications. Critically, the friction modifiers and other additives in ENEOS ECO-ATF PLUS have been carefully screened for top-level compatibility with the rubber, nylon, and plastic materials used in the components of automatic transmissions.

Building on that foundation, ENEOS ECO ATF OE+ is a next-generation, mid-viscosity, fully synthetic ATF designed to deliver enhanced fuel efficiency, broad OEM compatibility, and outstanding performance under a wide range of driving conditions — and builds on the proven performance of ECO-ATF PLUS with expanded coverage and improved low-temperature fluidity. This optimized formulation features high-quality base oils and a precisely balanced additive system that provides excellent oxidation and thermal stability, shear resistance, and anti-wear protection.

The second philosophy is OE precision. ENEOS's Import ATF series targets specific OEM requirements rather than a broad compatibility window. ENEOS Import ATF | MODEL T-W is automatic transmission fluid engineered specifically for Toyota and Lexus vehicles that require Toyota ATF Type WS Genuine Fluid, formulated with select high-quality synthetic base oils combined with unique additives. Similarly, ENEOS Import ATF | MODEL N is automatic transmission fluid engineered specifically for Nissan and Infiniti vehicles that require Nissan ATF Type Matic S, K, J, or D Genuine Fluid. For Korean makes, ENEOS Import ATF | MODEL SP PLUS is automatic transmission fluid engineered for specific vehicles manufactured by Hyundai and Kia that require Hyundai or Kia ATF SP-IV fluid.

Why ENEOS ATF Stands Apart

The foundation of ENEOS's ATF credibility lies in its OEM relationships. ENEOS has developed engine and transmission oils for the majority of car manufacturers throughout Japan and Asia — and each partnership begins with an invitation from an automotive manufacturer to develop vehicle-specific lubricants. That same engineering rigor is channeled into retail ATF products, meaning the fluid in the bottle reflects the same standards used in factory fills. Thanks to joint research and engineering with Japanese automakers, the ENEOS in-house R&D team develops outstanding lubricants with advanced additive and base oil technology.

ENEOS ECO-ATF PLUS is a multipurpose ATF that can be used in both regular automatic transmissions and in the increasingly popular transmissions that have slip-lockup control systems — a design feature that reflects how closely the engineering team tracks evolving drivetrain technology. Whether you drive a Japanese import, a domestic vehicle, or a Korean nameplate, ENEOS offers an ATF solution precision-matched to protect your transmission and support long-term shift quality.
