Next Generation PAOs to Improve Fuel Economy and Energy Efficiency in Engine Oils and EV/Driveline Fluids

Fuel economy has been the major driver in engine oil and EV/driveline fluid development as CO2 emission mandates are getting more stringent and challenging. While moving towards low and ultra-low viscosity fluids is an effective formulation strategy to improve fuel economy, it poses challenges in wear protection, deposits and oil drain intervals. SpectraSyn MaX is the next generation PAO (polyalphaolefin) family from ExxonMobil.

SpectraSyn MaX provides excellent low-viscosity, low-volatility (LVLV) balance, enabling low and ultra-low-viscosity engine oil formulations without compromising additive treat rates or Noack volatility. SpectraSyn Max also exhibits lower traction, which can lead to improved energy efficiency, and superior oxidative stability that also make them desirable in low-viscosity EV/driveline fluids.

Important properties of SpectraSyn MaX are presented along with their performance in finished formulations of engine oils and EV/driveline fluids.
