You can deduct expenses for the business use of your vehicle. You can use:

Actual Expense Method:For the actual expense method, you must track the actual expenses paid to use your vehicle for business. Expenses include: gas and oil; repairs and maintenance; Insurance; vehicle registration/license fees; garage rent; auto lease payments; vehicle depreciation.

If you use your vehicle for both business and personal purposes, we'll calculate actual expenses by applying the business percentage we determined from the mileage breakdown you entered on a previous screen.

The other method is the standard mileage.  If you have  a log book or daily record that would include details about how, when and where a vehicle was used for business purposes.  The written record of your business mileage could be a log book, diary or calendar that would include details about how, when and where a vehicle was used for business. It's smart to take notes about your destination and purpose of the trip each time you drive for business; this is really what the IRS is looking for.
