My wife took my car to work today. On the way home she stopped to put gas in it.
She says that she put in about a dollars worth of diesel before she realized it. She then put in about four dollars worth of gas.
What should I do?
Will this small amount of diesel do any harm?
She drove about 30 miles to get home.
