How to Choose

Scientific Basis and Evidence for Viscosity Improvers

Research and industry testing show that modern VI improvers and associative thickeners work by increasing fluid thickening efficiency at high temperatures while minimally affecting low-temperature flow. Laboratory methods such as kinematic viscosity measurements at 40 and 100 degrees Celsius, viscosity index calculation, shear stability index testing, and oxidative stability tests consistently demonstrate the benefits of well-formulated VI improvers. Peer-reviewed studies and industry white papers also document how polymer architecture, molecular weight distribution, and associative groups influence shear retention, thickening efficiency, and compatibility with synthetic basestocks and additives. The result is improved film protection, extended drain intervals, and more stable viscosity across service temperatures when the right VI improver is selected and blended to specification.

How they work: Polymers expand at high temperatures to increase high-temperature viscosity while collapsing at low temperatures to preserve flow.

Shear stability: Laboratory shear stability index tests predict how a VI improver will retain viscosity under mechanical stress in pumps and gears.

Compatibility: Studies show matching polymer chemistry to PAO, ester, or hydrocarbon basestocks reduces additive separation and performance loss.

Performance metrics: Key tests include kinematic viscosity at 40 and 100 C, VI calculation, HT/HS, TOST oxidative testing, and engine or gearbox bench validations.

Environmental and regulatory research: Ongoing evaluations in Canada emphasize low volatility, reduced extractables, and supplier documentation for local regulatory compliance.

Practical outcome: Data-backed selection typically yields longer oil life, more consistent film strength, and predictable multi-grade performance across Canadian climate extremes.
