This topic is for MPV owners to post and compare their actual MPG.

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.

highway 15, combined 21; why??? by johnbullus

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

MPV gas mileage sucks by budreaux

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.

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.
