Synthetic low viscosity ATF, designed specifically for TOYOTA and LEXUS cars, equipped with latest generation AISIN-WARNER automatic transmissions. The global tendency (the index WS means World Standard) is lowering viscosity of modern automatic transmissions to reduce inner resistance losses, thus decreasing fuel consumption. This is why the viscosity grade of Toyota ATF WS is lower than the viscosity of previous TOYOTA specifications requirements, constituting less than 6 cSt in operating condition (for example, water viscosity is 1 cSt). The product provides full protection of all parts and reliable performance of automatic transmission in high loads. The extended service life of this fluid is sometimes referred to as “life-long”.
