Which item has the greatest impact on the operating costs of cars?

Miles driven per gallon of gas consumed
Cost of oil changes
Sales tax
Insurance premium rates

The correct answer is: Miles driven per gallon of gas consumed

The miles driven per gallon of gas consumed directly affects the efficient use of fuel in a car. This can greatly impact a car's operating costs as the more miles a car can drive on a gallon of gas, the less frequent and costly fill-ups will be. The cost of oil changes and sales tax may also contribute to operating costs, but not as significantly as fuel efficiency. Insurance premium rates are also an important factor, but they are not directly related to the actual operation of the car and can vary based on individual factors such as driving record and location. This makes miles per gallon the option that has the greatest impact on overall operating costs.
