Yes, if the mileage is NOT commuting back and forth to work or for reimbursed miles, then you can deduct mileage (for which you were not reimbursed) as a job-related expense.

Note, though, that job-related expenses (mileage for work) is part of the itemized deductions, therefore you must itemize expenses to include this deduction.  And, the deduction is subject to the 2% AGI floor, meaning only the amount of job-related expenses that are over 2% of your adjusted gross income will be included as the job-related expenses in your itemized deductions.
