jump on the bandwagon - the thread for the ultimate mpg number. Post your mpg, give advice on how to get better mpg, questions why you're getting worse than everybody etc

I'll get it started:

based off mpg indicator in dash: 19city/23-24 hwy

lots of stop/go, traffic, etc.

about 10k miles ago replaced fuel pump, o rings.

recently replaced air filter, changed oil to synthetic

yesterday replaced spark plugs (champion platinums), cleaned MAF, hoping to see some mpg gains this next fill.

looking to replace TCV with ipd's to get some more mpg.

25ish mixed city and highway

A good amount of stop and go.

Lead foot and luv performing the Italian tuneup once a week.

200k and needs a full stage zero.

GTX 10w-30 high-mileage burns about 5 quarts every 3-4k.

Tires are just about worn out.

Exhaust leak, O2 sensors are crusty as hell.

P0455 OBDII code.

DEAD inspection

Bottom line it really doesn't matter. I abuse the stuff out of this $1,200 commuter car and only replace what is completely necessary. I still get better mileage then my Expedition.

As per the message center I'm pulling around 22.1 mpg. It's dropped atleast 2 mpg since I brought it home 1.5 years ago at 51k. Now it has 80k, new fuel filter, new NGK iridium plugs, full syn 5w30, good tires (Z rated though), and a CAI kit from Eurosport. It runs like a raped ape at times, and other times it acts like there is an anchor hooked to the back. No codes....

If you don't mid, Im curious about the cost of your fuel pump replacement. I had to have mine done in June and it cost close to a thousand dollars. This thread is a great idea. Keep at it.

I didn't pay for it, the original owner did. Before I purchased I copied the VIN down, did a carfax and called up the dealership that serviced the vehicle. They faxed me a copy of the complete service history.

October 18 2005, 30101 miles

Checked fuel pressure and replaced fuel pump

Parts $294.31

Labor $202.40

19 to 22 city - 27-30 Hwy @ 70mph (thanks to dp and catback) But no stomping the throttle to get those numbers.

The best I have gotten on the T5 is 35mpg when hypermiling.

Click me for hypermiling tricks

Its excruciatingly boring (60 mph fwy) and I got a cramp in my leg from modulating the throttle over 150 miles. <_<

Is that an "in the tank" fuel pump? I think I got ripped off really bad and am going to the BBB. Thanks

23.9 average.

I use 92 octane gas.

I try not to accelerate and brake rapidly, but when I deliver pizza, its inevitable.

And thats with me driving like a fool. If I drove a lot better/slower on the freeway I could maybe hit 25.

That's in KMs for the record. It's nice to see that after driving for 20kms I still had 990 more to go. I believe that the reading won't go any higher.

As for mpg I'm averaging 27 mpg (8.7L/100KM) with city and highway over the last 3000miles(5000km).

I would lie to thank the manual tranny for my milage. The live reading also let's me know how much fuel I waste when I drop the hammer, not that it deters me too much.

Sorry for the UBER large pic (complete with bad img quality. Don't know photo editting and this is off my mobile)

Nice work, rolling down a mountain definitely would help. In Toronto we have only hills, and not even big ones at that. You should have put it in N and just rolled for a few miles and then you could even get more!!!

i did have it in N for most of the downhill (about 15 miles +/-).

it might have been a little higher if i didnt have to drive through town to get to the gas station.

i was running on fumes most of the way down. :o
