Why do Chevron base oils have better low-temperature performance than Group I base oils?

Compared with solvent dewaxed base oils, Chevron base oils contain virtually no normal paraffins (wax), and they are very responsive to pour point depressants (PPDs). Therefore, under low-temperature, low-shear conditions, lubricants formulated with Chevron base stocks are not as prone to solidification, as are typical’ Group I base stocks.
