PAOs have inherently high viscosity indexes (VI) while maintaining excellent low-temperature performance. Both properties are critical in protecting engines at temperature extremes. Low temperatures can rob a lubricant of its ability to reach critical parts, while high temperatures can thin and break down an oil, crippling its lubricating ability.

However, two different lubricants with the same viscosity index may perform dramatically differently at low temperatures. Other factors shown on the chart below need to be considered.

Because PAOs are synthesized molecules, they don't contain components that might adversely affect their desired properties. As a result, our PAOs require fewer VI improvers and are less likely to create performance-limiting deposits.
