For oils and lubricants, viscosity at the cold end governs start-up and pumpability while the warm end governs film strength. The shape of the curve in between is what specification work depends on.

The full working window

We profile oils continuously from −30 °C to +40 °C, complementing single-point methods like ASTM D445 and feeding viscosity-index calculations.

Repeatable, automated runs

Every sample sees the same thermal program, so candidate oils compare cleanly.
