There is a pump that screws into quart oil bottles that will pump the oil out. It is in the marine section of most Walmart stores and it is used to fill the lower units of outboard motors. You can romove the fitting for the motor but then have a pump with the correct threads to attach to your oil.
Here is a link to West Marines site that sells the unit.
