Only claim the miles driven for business if you use the standard mileage rate. If you use actual expenses, you can add them all in. If you use your car for our spouse or not exclusively for business, you need to assign a percentage of the time you use your car for business and multiply that percentage times your car expenses.
I will include a link because that gets a bit complicated.
