#1483 of 5511 Premium gas recommended for Sienna
Dec 21, 2004 (3:09 pm)
Here is an extract from the above weblink of cars.com:
the 2002 model year, the Odyssey doesn’t call for premium fuel, as it had from 1999 – 2001. For the Sienna, premium gasoline (91 octane) is recommended. It’s not required, so no damage should result from running on 87 octane gas, but all the manufacturer’s ratings — such as engine output, fuel economy and emissions — are based on the more expensive fuel. Regular gas is likely to reduce power and possibly mileage — though probably not enough to nullify the lower fuel cost."

Good link you found. Now will someone email Toyota and see if they dispute that? Seems a bit deceptive not to mention it in their specs. Nor does it seem to jive with the EPA's 2005 Fuel Economy Guide (link).
You should be able to extrapolate what type of gas the EPA used in coming up with the Sienna's mpg figures (even though there's nothing in the notes to indicate that premium was used). All you need to do is compare the Sienna's annual fuel cost ($1,285) with the method used to calculate it:
"The estimates are based on the assumptions that you travel 15,000 miles per year (55% under city driving conditions and 45% under highway conditions) and that fuel costs $1.80/gallon for regular unleaded gasoline and $1.95/gallon for premium."
I'll leave that exercise to the math majors since I have enough trouble with my checkbook.

Your link is hardly authoritative, mackakava, and is the most slender of reeds to support the blanket (mis)statements you have repeatedly made on this topic.
#1486 of 5511 Magical Torque boost too?
Dec 22, 2004 (3:54 am)
Does it even matter?
Do you care about 10 increased HP at 4000 rpm when your engine will almost never be there anyway with an auto tranny? Does macakava seriously think that 91 vs 87 octane is going to magically give him an extra 10 ft/lbs torque at any usable RPM range? Or that he would even notice/care if it did?!?!
Even if the recorded HP figures are boosted by higher octane fuel (and it wouldn't be by much anyway) minivan drivers are going to be more concerned about TORQUE since the purpose of their vehicle is to people move, not see how fast they can max out their speedometer.
And seriously, the "car guy" usage is too funny. So lame.

"..likely to reduce power and possibly mileage..." Sounds authoritative to me. He also states that the Sienna's peak torque at 3,600 rpm may offset the Odysseys (2004, I won't mix an match model years to suite my preference as some posters will) horsepower advantage. Why didn't you mention that.

Let the facts speak for themselves. No need to discuss further.
The doubters will always rationalize their beliefs.
Seasons greetings to you and yours!
