I have tried to find out if there is a set amount per mile for running errands, taking my dad to appointments. I would be on the road for 5 hours just for driving to take him to his VA appointments. I live 2 hours from him one way. One month, I put over 1300 miles on my car just running errands, shopping, appointments, cleaning, etc.
As I mentioned, I am not looking for income, just some kind of reimbursement. Not for my time, but for mileage, wear and tear on my vehicle.
