chosen: It is best to check your owner's manual to determine what type of fuel your vehicle requires. Generally, regular grade gasoline is recommended for most cars and hybrid vehicles, as it provides good fuel efficiency and is less expensive than premium gasoline. For vehicles that require premium gas, such as higher-performance or high-mileage cars, it is best to use premium grade fuel as it provides better performance and protection for your car's engine.
