Thanks for all the information guys.
So far I'm averaging 10.4 L / 100 KM (that's 22.6 mpg) - with a combo city / hwy; that's well worse than rate assumed by VW.
I guess it's time to consider a few minor mods to get that under control.
I will certainly look into a K+N filter and possibly a short ram intake.
Would chipping the car void the VW warranty (pre-owned warranty - 2 yrs, 40,000 km)? Which chip do you guys recommend? My local mechanic will have to be doing all the work as I don't have a space where I can work on this car (live in a condo).
In the future, I will look into better tires as I go to a lower-profile summer tire/wheel combo and probably lowering it to improve the ride / profile.
Thanks again - keep the advice coming!

Somebody correct me if I'm wrong about some chips having a "lock" setting of some sort?
"chipping" or flashing the car with new software DOES NOT VOIDS ANY WARRANTY.
Please search before saying such things.
The gist of it to me seems to be that while technically the dealer cannot refuse to do warranty work unless the dealer can PROVE the chip is to blame in some way shape or form, you may still have a fight on your hands with some dealerships.
So, thank you for the correction - you are correct, TECHNICALLY it will not void your warranty. For me, it just isn't worth the fight with the dealership/bringing VWoA into things, but hey, to each his own! Thanks again for letting me know the real deal.
My 2007 Rabbit with 6 speed auto gives me between 26 to 32 mpg.
The 32mpg I averaged on highway doing steady 65 with no AC on.
I get 26 in the winter driving around the town. Summer with a light foot I would get up to 29mpg driving around.
Yes the car for its size has a horrible fuel economy. Germans don't have a clue how to build efficient gas engines. How come a larger Ford Fusion can get 34 on highway with comparable size engine? I have no clue why VW stuck that engine in that car. They don't have it in Europe. As usual VW always shoves inferior cars in the US market.
You got a stick right? Hop into neutral while going downhill or approaching a red light while youre still a good quarter mile out. Then get good at matching revs and hopping back into gear.
When i was in NYC, i was eating at a restaurant with my friend when Bill Murray passed by, took a french fry from our basket, dipped it in ketchup, ate it and said:"No ones ever going to believe you" before walking out.
I get 30 mpgs going at 70-75... My record is 430 in one tank, and i havent really tried to top it...
And we hwve said it many times, its more thn the car, its the driving style

dealers don't check for chips on 2.5 motor. nobody tunes these things like the GTI. they didn't even care when I brought my 2.5 in w/SRI on it for warranty work on a compressor, that I BROKE!!!! When I had my GTI, the same dealership told me they couldn't touch my car just looking out the window at it parked in the lot.
The dealer doesn't care what you do to a naturally aspirated car. NOTHING you can do to these N/A motors is going to cause the stress that a chipped GTI goes under. Turbo cars get chipped and max out their stock turbo, this is why dealerships don't work on them if they can get out of it.
If you bought it CPO, just tell them it came that way and you have no idea what they're talking about if they ask. It takes a very clever technician to diagnose an encrypted flash program, one that likely has more important things to worry about. That or it takes a moron to rev your car to 7500rpm and realize its chipped, which is technically not the proper way to diagnose it so they would not admit to doing this.
As far as fuel economy. you're not going to get it out of a 2.5L gas engine... DUH. I average 28mpg which is basically what my MK4 vr6 got. This 2.5 is NOT an economy motor!

About 15,000 miles ago I purchased a set of Bridgestone Ecopia all season tires and I've seen a nice increase in MPG. They perform just as good as my previous Bridgestone Potenza A/S tires, but I consistently see 32 MPG on the highway, doing 80 miles an hour. The best I had seen with the Potenzas was 28.
I honestly think this is a total waste of time and effort trying to get more gas mileage out of your rabbit. It has an engine that has some pep, its torquey, it is ment to be driven. I have a somewhat heavy foot and still get avg 23-24 mpg driving 75% on high way at about 70-75mph. If you are really so concerned about gas mileage than trade it in for the new TDI rabbit or another tdi or hybrid car. Otherwise it's just adding yourself a headache being anal to add another 1-3 mpg to your overall gas mileage. Enjoy the 2.5, drive it like it's ment to be driven .

Oh, those numbers you all wrote is looks like a dream for me...
My 08 Rabbit, stock has once 23mpg mostly highway but daily average is 18-19 mpg 50/50 city/ highway but constant stop and go on both... I was wondering if something wrong with it or it's something wrong with my foot ?
I have a 2005.5 Jetta, 2.5L. Best mileage I have gotten so far, has been right under 29mpg. And I do drive mostly highway to and from work. Otherwise, I'm somewhere between 24-26 mpg. I don't try too crazy, but I do get on it every so often. It does help to not rev above 3k, that's for sure. My mileage improved after I replaced my plugs and cleaned out my system (Seafoam anyone?). But I dunno, it's a 5 cyl, I don't expect 30+, but I bet I could do it with nice long highway drives on a trip or such. My old Grand Am GT (2.4L 4 cyl 5-spd) used to get 32 mpg all the time around the city, but again, it was a 4 cyl.
On that note, I did just put on a new catback system, and was told my mileage would drop, so we'll see. I would like to do a cold air intake, I've heard that helps a little.

On my Rabbit I get about 26-27 mpg avg. and my low gas light comes on around 320-340 miles.
Start with the free options like reducing unneeded weight and drag, but consider that to yield anything more then 2-3 mpg improvement you need to do more drastic things that are either expensive, and cancel out the purpose of saving gas, or heavily modify your car.
Mid to upper 20's isnt bad but if gasoline rises another .50-1.00 and looks like its going to stay there for atleast a few years I would seriously consider a tiny car that gets upper 30's or more, providing it would be fairly close to an even trade in terms of car value. However a tiny car like a Smart Fortwo or Scion iq doesnt bother me because I rarely have other people in my car, I don't drive alot, and dont carry around alot. Going from 27 to 37 mpg will yield a $350 savings per year on gas for me if gas averages $4.50 which I think is very possible. Not worth it if gas averages less then that in the years upcoming and or if the replacement car is more expensive.

I have been averaging in the high 20's since I bought this car almost 2 years ago and over the last 18k miles. I have only missed a few fill ups in my log, and I have averaged as high as 32mpg on a single tank and my low is around 24 or 25. I usually don't beat on the car at all. I have a 35 mile commute each day which is mainly non-congested back roads a small amount of highway. Just take off easy and don't romp on the gas, I normally shift between 2-2.5k maybe 3k (unless getting on the highway), and i typically go straight from 3rd -5th in normal driving (5 speed). I have had a Neuspeed P-Flow for about a year and half and put on a votex exhaust about a month ago.
While not the most fuel efficient car I don't think it's that bad.
I'm now driving a 98 GLX that gets between 25-27 miles to the gallon depending on how I drive it. My wife drives the newer 07 Wolfsburg 2.5 and has gotten around 28 on it through two tanks. I can drive the GLX round trip 16 miles a day for a week on $20 worth and she drives the Wolfie about 50 miles roundtrip a day for a week with a fill up.
I'm completely content with the mileage we're getting out of both cars because both are an impressive gain over the $100 a week I was spending on gas driving my 2006 Dodge Dakota that averages 17 miles to the gallon.
Weld up your combustion chamber, polish it, surface it -0.005, and dynotune it. fuel economy will get better I have done stuff like this before on previous builds.

A1an - try taking the roof rack off if you aren't using it all the time. I usually go at least 350 miles and re fill a bit before the gas light comes on. Racks tend to add a lot of drag to the car.
I average about 29~30 mpg on my way to work, which is 15 miles away (with a 2.0t). I, stay in nuetral a lot of the time and use cruise control on the more flat sections of roads. also i'm not sure but according to some the tune will help your mpg, maybe a cai.
I also have bad milage but few fill ups I decided to try higher grade gas and I was suprised that my milage go up to 22-23 mpg from 17-18 mpg even though I have sticking caliper at the back and same driving routing as always.
I was using 87 grade but filled with 89. Back in mainland I always used 89 with ethanol for best result as well. It's no in my head as I calculate it after each fill up.
