Should I use regular gas or premium gas in my car?
<|assistant|>
Most modern cars come with either a "gas-saving" or "economy mode" setting or an automatic gas saving system that will switch the car to the optimal grade of gas depending on the circumstances. If you are unsure what grade of gas to use in your vehicle, it is best to check your owner's manual and follow the manufacturer's recommendations.
