    Just go with whatever maker suggests. They always have real information to returning up their suggestions. Its not like they have a share in the gas organizations. If that was the situation then every producer would only suggest top quality.

    premium gas has the same amount of ethanol as regular.

    The ATS works fine on regular gas. Remember Cdn regular is generally better octane than U.S. regular.
    I bought my ATS after 25,000km of rental use and you can bet it never had any super going into it.
    Sometimes COSTCO premium is only a few cents more expensive than regular so when I'm at Costco,
    I fill up with super. Honestly, I cannot feel the differnece. 4 cents worth.

    As an ATS coupe owner, I have used premium gasoline from day one; it costs me around 5.00 max over using regular. I was obliged to use regular when running short in the boonies and the result was engine knock when the car was pushed. Under normal, Interstate conditions, it made no difference but gas mileage fell by a couple of miles to the gallon. My previous vehicle used a Ford V8, the Euro design used in the Lincoln LS. It needed premium as regular certainly caused a drop in performance. Regular gas can be used in the ATS but premium does ensure no knocks and a seemingly smoother ride from an engine that can be rough at the top end.
