    In the "Real World," my 2004 MPV got 24mpg in mostly hwy driving(say 75%hwy) calculated over 2 tanks of gas. Feel like it is getting close to what EPA indicates. Satisfied. :P
  • Hello Everybody,

    so I took my first HIGHWAY ONLY trip on the 4th of july weekend. I put 178 miles on highway, from 8am to 11 am in a 75 F temperature, using AC 80% of time. I was cruising between 70-80mph.
    Much to my surprise, I got terrible gas milage: 15.67 mpg... (i filled the vehicle up before entering higway, and after puting 178 miles filled it up again - i got 15.67 mpg...)
    What is the probable cause?

    I take very good notes on my fuel economy.In the last 6 month, which translates to 5610 miles driven, my average mpg is 20.89 mpg. This is combined city and highway driving in chicagoland area.

    What is your opinion?
  • I just took a long trip and got 25 miles to the gallon in my 2001 MPV.
    If you don't get that much, I suggest you check the tire pressure. Also having the fuel injectors cleaned and a tune up may be on order. This is my second MPV abd so-far my favorite
  • I have a 2001 MPV and have calculated around 18 mpg highway (and this was right after having new plugs, wires, new coil pack and injectors cleaned). City, I get even less. I noticed that highway driving, at 70 mph the engine hovers at around 3000 rpm (yeah, this is way more than it should). I'm not sure if I have a lower geared transmission or if something is just not working right (yes, I have checked and overdrive is on). Flukee, I would like to know exactly what your rpm's read when you are at 70 mph.

    Talking about gas mileage, my 2001 mpv is going crazy on gas mileage, talking metric system for every litre it travles 6 km, tried to convert to mpg which is 14. mpg
    and that is not good.
    I there any soultion to avoid this.

    We love our MPV in part because it gets about 21-22 mpg when we drive the I5 between Los Angeles and San Francisco as we do several times a year. Our total driving is 380 miles door to door; with much of this highway posted at 70, we drive 70-85. Although mostly flat, only a modest part of this is "freeway" driving; rather most is one or two lanes each way, undivided, with the usual passing and dealing with trucks needed.
    My recollection is that at 70mph the engine turns at about 2600. With a gentle push on the gas, the car will speed up slowly and generally maintain rpm. However, if the cruise control calls for an increase in speed or you press down on the gas, the transmission shifts down (incredibly smoothly--you only hear the revs), and the rpm jumps to maybe 3500. Our car has low miles--25,000--and has been dealer maintained. Strangely we had to replace the O2 sensor at the last service (perhaps the secret of the performance), and haven't made the trip since then.

    Mostly highway with extremely light load (for a minivan). My driving is mild, rarely exceeds 65 mph. But A/C was on 80% of the time - that hurt. Trim is LX-SV.

    Just got back from a 550 mile round trip within Texas (in Texas the A/C is always on...)
    My '01 DX with 97.5K miles still gets about 22~23 mpg on the highway - around 20 in town. I fell in behind an 18 wheeler going 75 and let him suck me along the last half on that particular trip.

    The '01 at 70 MPH turns about 3000 RPM. The '02 and above with the transmission change is (I think) about 250 RPM less at that speed even with the slightly bigger engine.

    My O2 sensor makes the infamous "moose" call for 1 minute if the temp gets below 50 degrees (in Texas??) after engine start. This has been going on for three years and I never replaced it. Apparenly, in my case, it didn't affect the gas milage. Plus, I don't recall if we really had a winter in the last three years...

    By the way, I put Goodyear Assurance tires on all the way around about 15K miles ago - pumped up to 37PSI - really smooth - best tires yet.

    The "moose" call is not due to the O2 sensor, but due to the IAC (Idle Air Control) valve.
  • subearusubearu Posts: 3,613
    and it's typically referred to as a "fog horn" sound rather than a moose. The IAC is an easy DIY replacement.

  • bob57bob57 Posts: 302
    Sorry - we always referred the noise as a moose call three or four years ago in prior townhall discussions - I guess the term got changed through time....
  • subearusubearu Posts: 3,613
    either term would work. I'm just use to it being called "fog horn" from reading other sites out there. Even the TSB for it mentions "fog horn".

  • First full tank refill.. 20.65 MPG, 100% A/C and all city drive
    One question though, the fuel tank had less than 1/4 left and when I filled it only took 14.1 Gallons, Specs say 19.8 gallon full. I am guessing the fuel warning light comes on with 2-3 gallons in reserve..
  • subearusubearu Posts: 3,613
    21mpg city is good for city driving, my DW usually get about 18-20 city.

    The light does come on early it seems. I think the trend with most manufacturers lately seems to be this way. Not to mention that the only real time the fuel gauge is accurate is when it's full, noone makes a truly "linear" gauge anymore. Too bad the MPV doesn't have a trip computer like the GM and ChryCo vans, you'd see fairly accurate gallons used and could go off of that.

    New Highway and city numbers:

    Round trip from Raleigh to D.C and back, 2 kids, 2 adults and a lot of stuff in trunk..Average speed after subtracting the stops : 81 MPH to D.C, 77 MPH return
    To D.C: 22.63 mpg
    Return: 23.21 MPG

    3rd all city tank refill is 21.17 MPG, No A.C and all city driving.

    I am happy with the numbers, only thing is that I expected the HWY numbers to be sig higher after getting 21 MPG in city..BUT the van was full, AND we were moving pretty quick..My guess is, if I had reduced the "indicated" speed to 75ish, istead of 82ish, the MPG would have been higher..

    Just took my '02 MPV on a trip from Minnesota to Texas and back. Total mileage was 2733.7, about 350 of which was driving in-town. Total fuel consumption was 114.13 gallons. (I topped off the tank at the end at the same station and pump from where I started the trip.) That nets out to 23.95 mpg, right at the EPA highway average. The van was fully loaded with five passengers (three adults, one teenager and a child), a full cargo hold with a week's luggage, and every nook and cranny in the van filled with stuff. Most of the miles were on the freeway, with the typical speed being 70-75 mph with some slower stretches due to traffic/weather/construction. Weather was bad, raining most of the time. I am pretty happy with the fuel economy given the conditions. Also, the van performed flawlessly during the trip. The cruise control was spot-on and did a good job maintaining speed even when going up some pretty steep hills. I did notice some unsteadiness in strong crosswinds (30-40 mph).

    Entertainment note: Before the trip I bought a portable DVD player with a 9" screen ($89.95). I also bought a wireless FM transmitter for $20, which pipes the sound through the van's stereo system. The DVD player was just the right size to straddle the armrests of the front captain's chairs. (For a safer setup, one could easily attach the unit to the armrests with a strap.) The wireless transmitter caught some interference at time but generally worked well. It was well worth the money and an inexpensive alternative to a built-in system.
  • gus11,

    I'm getting bad mpg off my 2001 MPV, have ever since I got it. About 15 city/suburb and rarely more than 20 on highway.

    What's up with our vans?
  • jipsterjipster Posts: 5,345
    I'm getting about 24 mpg hwy on extended trips with air on in loaded down van. Must be your tire pressure.

    On a recent, mostly-highway trip, my wife averaged 15 MPG in her 2001 MPV (LX, I think). She has about 55K on the odometer.

    Any suggestions? I was thinking she may just need a tune-up, but it has been suggested to me that the fuel filter may be to blame.

    I have constantly watched my mileage on my 2003 MPV and it's always around 17 in the city and up to 22 or so on the hwy.
    The engine seems a bit gas thirsty for the size of the vehicle, etc. I had a Grand Caravan before and it got consistently around 19 MPG all the time on a 3.3L engine.

    It all has to do with the gearing, etc and how your driving habits are. If you push the peddle on take offs from stops, the gauge will drop rapidly on the gas. If you ease up on the starts, it will improve. During the winter months, the mpg's drop off too.
