The present invention provides a process and an additive package for removing oil from solid material recovered from a well bore, e.g., drill cuttings and produced sand. In this process, the solid material is passed from the well bore to a separation zone. An aqueous acidic solution containing a polymer substituted with an amino group is introduced to the separation zone containing the solid material along with a halogenating agent and optionally one or more surfactants. The polymer, halogenating agent, and optional surfactant constitute the additive package. The polymer substituted with an amino group is preferably chitosan, and the halogenating agent is preferably a sodium hypochlorite solution. The mixture formed in the separation zone is agitated to cause a product of a reaction between the polymer and the halogenating agent to contact the solid material and remove residual oil therefrom.

In a vehicular drive system for a hybrid vehicle, in which driving forces of an engine and a motor are transmitted through a power transmission mechanism to driven wheels, a common oil stored in a transmission case and a motor case is used for lubricating the power transmission mechanism and the motor. During travel by means of an engine, when a synchromesh mechanism operated by a shift fork isolates the motor from the power transmission mechanism, an oil return hole blocking rod, provided in the shift fork, blocks an oil return hole providing communication between the motor case and the transmission case, thereby preventing oil in the motor case from flowing into the transmission case, to lower oil level in the transmission case. Thus, during travel of the hybrid vehicle, driving force loss due to motor drag resistance and oil stirring resistance is minimized.
