    Hey gang!

    The wife will be taking delivery of her new car when it arrives in 2 weeks.
    I expect it will be filled with premium for delivery, but given the price of
    gas/gal, do we have to stick with premium?

    She likes the car and will not use the full capability of the engine anyway.
    so what do you think?

    I think you put in whatever the manual states. If it calls for more than
    regular, try a grade lower and see if it causes pinging. If so, bump back

    I used to own a 2001 Maxima SE before the 06 Accord I currently own. It
    recomdneds "premium for max performance" after having the car for a month I
    tried to use regular in it for a tank. and let me say... I NEVER did that
    again.. Modern engines that require high octaine gas have a Knock sesnor in
    it, so if you put in lower grade gas than what is calls for, it retards the
    timing to compensate for the lower grade gas. when my maxima did this it ran
    like absolute crap... also the "knock sensor" has to "sense" the knock
    before it can retard the timing, so your engine is knocking before it
    retards the timing.... long story short, it only costs your a few dollars
    more per fil up (2-3 bucks) to get premium... like i said with my Maxima,
    one tank of regular made me NEVER put anything BUT premium in it. I'd say
    you might be able to get away with mid grade.. but I'd do that at the bare
    min... in my opinion

    I think that you read the Owners Manual and go from there for every aspect
    of being the owner of a Honda.

    That aside, every Honda vehicle I've owned over the years has come from the
    factory made to achieve the best fuel mileage using regular fuel. I have
    tried other grades of fuel and none of them have achieved any significant
    differences in mpg to warrant the added cost of the higher grades.

    The Prelude I previously owned developed 200 hp at 7,000 rpm out of 2.2
    ltrs. You had to run premium in it. The SI developes 197 hp under the new
    SAE hp rules which means it likely is comparable to the older Prelude but
    with a smaller displacement. Run 87 octane at your own risk. But, I have
    to ask why you bought the SI. The EX would have been far more appropriate
    if you wanted gas economy on regular gas.

    I have a 2006 si, I filled the tank and add gas when I hit a quater mark.
    The price for filling up to the full mark is not so bad as filling a near
    empty tank. This engine gets good mileage with fast starts and hi revs. The
    cost for hi test is worth it for the fun one gets from driving this car.
    stay out of food houses and spend the cash on gas.

  8. We still don't know: what does the owner's manual say the fuel
    requirements are for this car?

    Premium, in the manual and at the gas filler.

    We take delivery tomorrow evening - she is pretty excited!

    Based on the feedback, it will be premium all the way!

    PS - she liked the seats better than the EX. That and the spoiler! I know, I
