What does your owner's manual recommend? I'll bet it recommends 93 octane (which I think is what you mean by super). If that's what it says that's what I'd give it. Any lesser grade will cause the engine to knock and it won't burn as clean - you'll actually not get as good of mileage. I have an Acura that calls for 93 and occasionally I'll put some 89 (mid grade) in there with the 93, so I'll average about 91. But the savings are negligible.































Like my daddy said when I bought the luxury car... if you can afford the car you can afford the high grade gas you have to put in it.

I've heard that using 93 octane is your best bet so the engine will run the smoothest it can, not to mention it will give it a little more power, Mobil gas is the best to get (they say its better quality and will give you more miles to the gallon). Always fill up at night or early morning you will get more because the liquid is more dense at cooler temperature (More gas for your money). Gas is also more expensive closer to weekends so fill up in the middle of week preferably Tuesday or Wednesdays.
