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:
Low volatility for extended drain intervals
Improved energy efficiency
Low CCS viscosity for better engine starting and low-temperature oil flow
Cost-effective low-temperature and volatility performance when blended with mineral oils

In the ASTM D445 tests, SpectraSyn Plus PAO demonstrates a better balance of Kinematic viscosity (at 100°C) and Noack volatility compared to Group III and Group IV reference oils.
ASTM D2270 measures the apparent viscosity of engine oils and base stocks between -5°C and -35°C using a Cold Cranking Simulator (CCS). Noack volatility is measured by ASTM D5800. SpectraSyn Plus PAO demonstrates improved volatility compared to a reference conventional PAO.
