Summary:

It is important to reduce the viscosity of automatic transmission fluid (ATF) in order to improve fuel economy. However, in general, low viscosity fluid can cause metal fatigue, wear, and seizure. It is necessary to increase the viscosity of the fluid at higher temperatures to maintain the durability of the automatic transmission (AT). The key point is the selection of the base oil and the viscosity index improver (VII) with both a high viscosity index (VI) and excellent shear stability. On the basis of this concept, a new generation high performance ATF named WS was developed. WS can achieve the highest level of fuel economy, while maintaining the durability of the AT
