What’s the difference between the Regular, Midgrade and Premium choices at the gas station and does it matter which I put into my vehicle?

    Other than price, the difference is in the content of octane, with premium gas containing the most of the three. There is little difference in energy content when comparing regular to premium gasoline. Check your car’s manual to see which type the manufacture recommends. Regardless, the American Petroleum Institute declares that the manufacturer’s recommendations on whether to use premium or not is more of a suggestion rather than command.
