I believe the second generation Odyssey does require premium fuel (1999 - 2002), then they dropped the requirement in 2002 and made it such a great deal...
For Sienna, it also recommended premium fuel for optimizing performance for the first genneration (1997 - 2003), Toyota also dropped the requirement in 2003 for the current generation...
So both of them just need regular unleaded fuel, and that should be the norm for all cars except the sporty and luxury cars which need premium fuel to enhance performance...

If I'm not mistaken, the early previous gen Ody's were rated for both types of fuel. Now don't quote me but it was something like 215 HP on premium and 205 HP on regular. I have a family member that has a 01 MDX which requires premium. The 02 or 03 MDX went to regular grade with a boost in HP. As for a few cents difference for premium, in SoCal, a good price today is $1.89 for regular, $1.99 for mid grade, and $2.09 for premium. 12,000 miles per year at 20MPG = 600 gallons or $120.00. That's not chump change to me.

Most modern engines and have knock sensors so they will take advantange of higher octane.
As a result, many new engines are rated for both fuels. For example, the Nissan Quest V6 in our van is rated at 240 hp on premium and 230 on regular. Premium is not required. The torque peak is only five less, however. Going on a diet and taking the extra junk out of the vehicle would probably yield a better return on mpg.

We recently purchased an '05 odyssey EX-L RES and are only getting 19-20 mpg. I have spoken to our sales representative and she stated she has had 4 complaints of others with the same model. The Honda Representative was to the dealership and this was the first he had heard of the problem. Perhaps we should contact our selling dealerships, there may possibly be a problem with the 6c engine in these models.

ONLY 19 to 20 mpg is a PROBLEM? Sounds good to me. After all, this is a big, heavy, functional vehicle that can hold 7 people. And it's about as aerodynamic as a barn.

Is that combination city/highway? If it is, you have no problem at all.Great if only city.

First tank driven 291 miles yielded 18.1 mpg.
Second tank driven 297 miles yielded 18.04 mpg.
Van has 610 miles to date. Sixty percent highway miles. The improvement necessary to achieve supposedly understated EPA mpg estimates seems seems a bit daunting. I'll keep driving and keep calculating!
#758 of 1887 Vehicle cargo weight a problem?

I've read a lot about how vehicle weight affects mpg. At what point does anyone think vehicle occupant(or cargo) weight factor in? If you are hauling around 4 or 5 fairly good sized people(say 160-250lb)say total of 1000lbs. And someone else in the the exact(identical down to the fingerprints)vehicle with one other passenger for a total of say 300lbs...thats a difference of 700lbs.In city driving that could make a big difference.May this be part of the reason some of you are having lower mpg than expected?

You said: "with one other passenger for a total of say 300lbs...thats a difference of 700lbs.In city driving that could make a big difference."
I believe it would make a difference in city driving (constant acceleration/deceleration). However, the premise of VCM dropping three cylinders is that it requires less energy to keep mass rolling forward under highway conditions. As such, I don't think we would see dramatic differences. I'm also betting that those posting van MPGs aren't regularly driving 300 miles hauling 4 or 5 (160-250lb) occupants. I'm 180lb, wife 130lb, Kid1 40lb, and Kid2 22lb for a total of 372lbs at 18mpg. Funny how some are getting great milage of the lot and some of us are holding on in faith to this ethereal break-in phenonenon.
