I run premium (91 in California) its a few dollars more, for better gas mileage, and better performance. I've been using only Premium in all of my cars, since I can remember. I actually switched to 87 in my 21 2 liter accord, and it made a huge difference in mileage, and power, and Im not talking about gimmick.

With the handheld, the Accord runs 2-3 degrees more timing, and you can actually feel it. These cars that have higher compression turbo engine, you can really tell. I can also tell that flooring it, the engine wants to hesitate, not physically, it just doesnt react as quick as it does with Premium. I switched back to 91, last week, and now on the highway, Im back to averaging 31MPG on the highway, and for months, I couldnt get it over 26-27.
