Abstract
A spindle oil is hydrotreated and then hydrodewaxed in the presence of a catalyst containing at least 70 percent by weight of an intermediate pore molecular sieve in the support so as to produce a selected fraction having a low pour point and viscosity comparable to the original spindle oil, said fraction being then suitable as a 'cutter stock' for lowering the pour point of fuel oils.
