Low viscosity polyalphaolefins
To meet ever-increasing performance demands in the evolving marketplace, formulators use SpectraSyn™ Lo Vis PAO synthetic base stocks – available in viscosity grades from 2 to 10 cSt – to gain better low-temperature properties, low volatility and improved oxidative stability compared to mineral oil base stocks.
They can also be added to mineral oils for increased performance. They can be combined with SpectraSyn™ Hi Vis PAO, SpectraSyn Elite™ mPAO and Synesstic™ AN (Alkylated Naphthalene) blend stocks to formulate cross-grade engine and automotive gear oils, as well as various ISO VG industrial oils.

Enhanced Perfomance
Low volatility
For reliable performance in high-temperature operating conditions, formulators want base stocks that offer low volatility. In the NOACK volatility test (ASTM D5800), SpectraSyn PAOs demonstrate lower volatility at higher temperatures than Group II and Group III mineral oil base stocks.

High viscosity index
Comparing PAO base stocks at any given viscosity to polyisobutylene (PIB) and mineral oil base stocks, we can see that PAOs provide significantly higher viscosity index (VI). ASTM D2270 is the standard test used for calculating viscosity index from kinematic viscosity at 40° and 100° C. Higher VI translates to better stability in a range of temperatures.

Low viscosity at low temperatures
ASTM D5293 is the standard test method for apparent viscosity of engine oils and base stocks between -10°C and -35°C using a cold-cranking simulator (CCS). It is used to measure performance in low-temperature conditions. In this test, SpectraSyn Lo Vis PAO (4, 6 and 8 cSt) demonstrates significantly lower viscosity at low temperatures compared to a Group III mineral oil.
