Final answer:
The statement that colder states use a higher number oil is False.
Step-by-step explanation:
The statement that colder states use a higher number oil is False. The number or grade of oil used in a state is not determined by the temperature of the state. The grade of oil used in an engine is determined by the manufacturer's specifications and the engine's requirements. The higher the grade number, the thicker the oil and the better it can protect the engine under high temperature and heavy load conditions.
