    It's the same here as what you have, although I have seen in the past different octane high test; 91, 92, and 94. Come to think, I believe Costco's high test is 92, I can't be sure, but seems like I recall it being different than 93.
    I do go out of my way and buy gas without ethanol. That is getting hard to do now days.
