Abstract:
The invention relates to a method for analyzing a lubricating oil for low temperature properties. The method utilizes 2-dimensional gas chromatography (2D GC) to determine the amounts of paraffins and isoparaffins in the oil. In particular, the method analyzes for a particular isoparaffin fraction which is correlated to low temperature performance. The compositional information thus obtained is correlated with formulated oil Mini Rotary Viscometer (MRV) properties.
