ECO ATF 12 X 1 Qt

The ECO ATF 12 X 1 Qt automatic transmission fluid from ENEOS is engineered for drivers and technicians who demand reliable, consistent shift quality and extended drain intervals. This synthetic blend addresses the core challenge every transmission faces: maintaining optimal hydraulic pressure, friction stability, and thermal protection across variable driving conditions. Whether you're rebuilding a transmission, performing routine maintenance, or troubleshooting shift delays, selecting the correct ATF specification is non-negotiable—and ECO ATF 12 delivers OEM-grade performance in a convenient one-quart format for top-ups or complete system fills.

ECO ATF 12 is formulated with advanced synthetic base stocks and a proprietary additive package that manages friction modifiers, anti-wear agents, and oxidation inhibitors—critical for modern automatic transmissions operating at higher pressures and temperatures. The fluid's viscosity profile ensures smooth pump engagement during cold starts while maintaining film strength under high-load torque converter stall conditions. ENEOS synthetic technology reduces viscous drag within the transmission, improving fuel economy and reducing operating temperature, which directly extends component life and reduces heat-related degradation of seals and internal clutch materials.

Mechanics and DIY enthusiasts appreciate the one-quart packaging for convenience during top-up service intervals, while fleet operators and shops rely on ECO ATF 12 for full transmission fills across domestic and import vehicles. Compatibility spans most domestic automatic transmissions and many Japanese-market imports; always verify your vehicle's OEM specification against the manufacturer's ATF classification before installation. This fluid is particularly valuable for vehicles exhibiting early signs of shift harshness, delayed engagement, or elevated transmission temperature—conditions that worsen rapidly with incorrect or degraded fluid.
