Figures in the product data sheet

Every KORTEX product page lists these figures. What they mean: DEMO

Viscosity, 40 / 100 °C

28.4 – 168.2 / 5.7 – 19.7 cSt

range in the catalog

How thick the oil is: at 40 °C — at start-up, at 100 °C — at operating temperature (cSt).

Viscosity index

105 – 184

range in the catalog

How stable the viscosity is as temperature changes. The higher the index, the more evenly the oil works in cold and heat.

Flash point

220 – 244 °C

range in the catalog

The lowest temperature at which oil vapour ignites from a flame. Higher means less evaporation in a hot engine.

Pour point

−51 – −30 °C

range in the catalog

The temperature at which oil stops flowing. The lower it is, the easier a winter start.
