Does your location and type of gas sold (e.g., whether it has required additives for emissions) make a difference?

I seem to remember from the Subaru list a long time ago that people in areas of the U.S. that did not have to buy low-emissions gasoline had better mileage than those of us in smoggy areas...

Our first fill-up on our new EX gave us only 14 mpg, all city driving. Hope it improves...
 
Our 2002 Navi had 4,000 miles when we started our trip from SC to CT. Over close to 900 miles we averaged 25 MPG with 85% on Interstates. Day to day we get 19-20 MPG. The first 1,500 miles we got roughly 15MPG.
Around 24-25MPG is what we got on our 1999 EX on highways and 18 around town. Odys get exceptionally good mileage normally.
 
Disappointing mileage?

I've had a 2002 MB Ody for just over two months, and turned 10,000 miles last week.

The week before that, I returned from a round trip cross-country trip of some 7400 miles. I averaged 24.5mpg round-trip. I scrupulously filled the tank to the same level each time, and calculated the mileage to a couple of decimal points. And I could not have been more pleased. We got 28.5 on one tank, wind-aided, and as low as 19.5 when we drove in stormy Long Island traffic.

I drove back from the East Coast in four days of driving, two to Kansas, where I hid out over Memorial Day weekend, and two days to Los Angeles. The first day from Kansas I covered 1057 miles to Salina, Utah. Can't imagine a car more comfortable for the long haul than the Ody. 5-600 miles is a very easy day for me.

Called me "Thrilled in LA."

There is a difference in fuel economy between the reformulated gasolines and conventional blends, but it's not drastic -- something like a few percent worse with the reformulated gasolines. Your fuel economy will not be up to par until the engine is broken in... I'm not even bothering to check mine until I have a few thousand miles on the clock.
 
Just returned from trip to Los Angeles (from Salt Lake City). Started at around 650 miles on the odometer and came home at ~2200. Very comfortable trip.

Here's my problem: My best fuel efficiency was just under 20 mpg. I did enjoy passing other cars (and minivans) with ease on hills from time to time, but mostly we spent our trip on cruise control.

Here are my questions:

1. I averaged about 80 mph. At what speed is fuel efficiency greatest (i.e., do I start to burn more gas per mile at higher speeds?)

2. Someone mentioned that I should start getting better fuel efficiency after the Ody is broken in. Any science to this, or is this another "all the nutrients are in the orange rind" sort of fact?

Thanks,

Ryan

What Fred failed to tell you is that he drives to and from work with that strong Oklahoma wind at his back (both ways).
This theory works well either TO or FROM work, but one way or the other, I heading INTO the wind. So it's a wash. I just can't get Mother Nature to cooperate.:stupid:

Just got back from a week long trip in our 2002 EX. We started with about 750 miles on the odometer and have returned with about 2000 miles. With two kids, a few hundred pounds of stuff, a big hitch mounted rack and four bikes hanging off the back, we averaged about 24 MPG heading from sea level to about 4200 feet altitude, with the A/C on almost constantly and averaging 70-80 MPH. The return trip had a bit of a tailwind and we were drafting other cars and again averaged 70-80 MPH and our last tank was over 29 MPG, with about a 28 MPG average for the entire return portion.

We purchased our Ody at the last moment, needing a van for this trip but having had our previous van (93 Previa) totaled a couple of weeks ago by a driver who ran a red light. Both my wife and I are fairly aggressive drivers and found a sweet spot in performance with cold tire pressures of 44 front, 42 rear. This still provides a smooth ride (to us) with about equal handling to the Previa, which had upgraded shocks and stock springs, and might explain our gas mileage.

BTW, I've read the numerous discussions about the "break in oil" but decided to change ours right before the trip. I used 5w-30 Mobil 1, which noticeably quieted the engine down during both hot and cold idling, and gave us confidence to run the car hard on the way back.

Great forum and great information here!

Well, we have about 1500 miles on ours so far and it's mostly been on short trips (<10 miles) with a few longer drives mixed in when I can get hold of it. Anyway, we're only getting about 15 mpg or so -- that ain't right, is it? :(

15 mpg could be correct based upon your driving habits. The short trips will really kill your mileage.

Wierd -- my original message looks garbled and the reply to it looked hosed too, but the quote in this reply looks right -- at least in the composition window. Wierd...

Sorry about the multiple posts -- curious to see if this one works.

Our first few fill-ups were all in-city driving, never more than a mile or two of freeway at a stretch, and with lots of stopping and starting, up and down hills. The tank from the dealer (don't know how full it was really filled) was about 16 MPH, and subsequent fill-ups never had it below about 18.5 MPG.

We live in the Seattle, WA area, which has had pretty mild conditions, with daytime temps fluctuating between 50 and 80 degrees F., and pretty much dry the whole time we've had our Ody. However, lots of the stops are at the bottom of hills, so we lose all momentum at the lights.

We haven't noticed any real difference in gas mileage due to driving more aggressively. I'm sure frictional and pumping losses are greater when the engine is rev'ed up higher, but this is offset by the fact that the Ody spends more time in a higher gear getting more MPG. I'd seriously suggest checking your tire pressures. Hysteretic losses in wide tires are really pretty high if they don't have the proper pressure. Those tire gauges that are now for sale sound like the deal!

I have about 600 miles, four tanks all around 14mpg, mostly city driving. I expected much better than that. Other than that, the van runs great, the engine smooth so I don't think it is a mechanical problem. I have two other cars that only my wife and I drive, an Acura Legend with 120,000 that easily gets 20mpg and a Toyota Camry with 100,000 that consistantly gets 25mpg and much better for highway drives. I hope the Ody will improve to at leaset 18mpg, I'm very dissapointed in the gas milage.
 
Fuel Economy

We have an 01 Emeral Pearl LX. On long routes/Fwy driving we get around 21-24 mpg; depending upon the load; 7 passengers and cargo load;

Typically the daily commute includes both Fwy and street driving and just this morning I figured that mileage to be around 18-20 mpg;

So all things considered I believe the Ody's mileage just as any other car, would greatly depend on individual driving habbits, properly maintained engine (spark plugs, air filter etc) and correctly tire pressure. And of course the AC during street driving will consume more fuel for sure.

It is still a gr8 vehicle to own and be proud of ;

:p
 
'00 EX w/85K on the clock. We get under 20 mpg in town-- very short trips, 5-15 minutes driving a trip. Highway we've never gone over 27 mpg, have had a range of 24-27. Tires filled to 40 psi all around- I think we'll try 44 after reading the posts here. Going to try 89 octane also. Maybe synthetic oil?
We've been a little disappointed, because a friend with an '01 has recorded over 35 mpg on some tankfuls. And he drives faster than we do! 70-80 mph, where we never drive over 75, usually 65-70.
My understanding is that fuel mileage drops above 45 mph, and the drop is significant for every 5 mph over 55.
 
This is v.hard to accept: getting 45 mpg on an odyssey !!
may be when it was a 4 cyl engine but on the 00 and upwards models, I dont think so .... anyone else exp the same ?
:)
 
correction: i meant to write 35 mpg?
