The cheap gas causes unnecessary, long term wear and tear on the engine and causes it to lose significant power. Not only that, more sludge forms. I could keep going, but the list would read more like a book, so I'll spare you. The point of this rant is to just say, use the good stuff. It's worth it in many more ways than one.

Is that still true for modern engines that "Recommend" Premium? I thought the computer can detect the octane you're running and adjust to handle a lower octane without damaging the engine.
