👉 The PDAF fluid, or Propylene Decyl Ether fluid, is a specialized lubricant primarily used in high-performance engines, particularly those employing direct fuel injection systems. It's a synthetic lubricant known for its exceptional thermal stability, low volatility, and high viscosity index, which means it maintains its consistency across a wide range of temperatures. This makes it ideal for high-temperature environments, such as those found in modern racing and performance vehicles. The PDAF fluid effectively reduces friction between moving parts, enhancing engine efficiency and longevity while offering superior protection against wear and tear compared to conventional oils.
