To meet increasingly stringent emission regulations, automotive original equipment manufacturers (OEMs) demand lower and lower lubricant viscosity grades for engine and transmission oils. Formulators turn to lighter base oils, which typically have better low-temperature fluidity but also tend to have high volatility that can increase emissions and oil consumption.
With its exceptional combination of low volatility and low-temperature viscosity, SpectraSyn Plus™ PAO synthetic base stocks allow the formulator to further optimize their base stock blends to achieve the required performance.
SpectraSyn Plus PAO is available in three viscosity grades:
- 3.6 cSt – Ideal for high-performance, low-temperature applications, such as greases and driveline fluids
- 4 cSt – Suited to a wide range of automotive applications due to Noack, CCS and viscosity characteristics
- 6 cSt – Suited for automotive and industrial applications that require good low-temperature and low-volatility performance.
