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.

MPV 2002 milage and RPM at 70 and above by nierlich

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.

My first tank in 2006 MPV did 20 mpg by valley

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.

RPM's and MPG by bob57

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.

and it's typically referred to as a "fog horn" sound rather than a moose. The IAC is an easy DIY replacement.

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....

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..

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.
