Thermal and physical properties of lubricants

Knowledge about thermal and physical properties of lubricants enables OEM’s to improve their equipment designs. Q8Oils has tested and measured the most important properties of some of its products. To support our partners we give them insight into this valuable information.

More and more OEMs use powerful design tools for the engineering of new equipment. In this process the lubricant is regarded as a crucial design property.

Why we measure thermal and physical properties

In a lot of cases general information about lubricants is sufficient as the thermal and physical properties of a lubricant change when the oil is ageing. However, in some cases empirical formulas and general oil properties are not enough and more accurate information about the lubricant is required to optimize equipment design.

In order to support OEMs with their calculations, Q8Research has measured thermal and physical properties of some of our products.
