Proven performance
Improved fuel economy
Using a 0W-12 engine oil in Volkswagon fuel economy test PV1496, SpectraSyn™ MaX PAO demonstrates superior fuel economy improvement compared to a Group III+ and a low-viscosity conventional PAO.
In a comparison based on a Toyota 0W-8 test,
SpectraSyn™ MaX PAO demonstrates enhanced fuel economy versus formulations using low-viscosity esters.
Compared to conventional PAO and mineral-based Group II and Group III base stocks, SpectraSyn™ MaX PAO demonstrates step-out improvement in Noack volatility.
In MTM traction tests, SpectraSyn™ MaX PAO demonstrated significantly lower friction coefficient/torque loss compared to Group II+/III+ and conventional PAO blends. This performance can enable improved energy efficiency and fuel economy.
Compared to Group III and Group III+ mineral base stocks and low-viscosity conventional PAO, SpectraSyn™ MaX PAO demonstrates superior oxidative stability, with lower viscosity and Total Acid Number (TAN) change after 192 hours at 170°C (using CEC L48 test method).
Formulating low-viscosity grades can be challenging. As the viscosity grade lowers, a “formulation squeeze” is created, offering less opportunity for performance additives. Thanks to its next-generation capabilities, SpectraSyn™ MaX PAO provides greater formulation flexibility.
This chart compares the performance properties of SpectraSyn™ MaX PAO with traditional low-viscosity PAO and Group III base stocks. Note that SpectraSyn™ MaX PAO provides superior balance of low viscosity and low volatility.
