2.5L Fuel economy thread.--UNOFFICIAL--

Still not entirely impressed with my mileage. Just fueled up, thought I was having a reasonably good tank and left the pump with a face on.

I still had a lot of room to go, gas light had just turned on and I was at 520km's.

Ran 94 this tank and got 25.3MPG, been watching my Torque Pro app and it put me at 34MPG. Fred, how accurate is your app, have you ran it for a full tank to see what it says for fuel economy?

Threw in another full tank of 94 today, we will see how this goes..

[Lwize]

I'm still in the 24 range with mixed driving and 87 octane ('09 Rabbit stick)
Haven't taken any long trips, so I've never cracked even 30mpg.

Does short-shifting and cruising around 1,500 rpm in city traffic matter?

[whitefang]

new member and first post.

So far,
in town only(Montreal) shifting before 2500rpm i average 420km on a tank of 89
On the highway non stop(ex: Montreal - Niagra falls) i max out at 750km.

[ajd187]

Average MPG is about 25, with a low of 22.65 in the dead of winter, and 28.08 in a warm week in March.

This is mostly mixed highway/city driving, about 50 miles a day. Waiting to take it on a long trip to see what we end up with on that.

[thygreyt]

32MPG


full hwy, cruising at 70mph.

[A1an]

26.4 on my last fill up with mixed driving (mostly highway though). It typically averages 26-28.

Worst I have had was just under 22mpg on the highway driving up to GA with this on the roof:

[SilverJetta2.5]

I tend to get 28-31 no matter how I drive, but have found out I can get a solid 30 running around in "S" mode commuting. mix 50/50

[cbs_24]

Using 93 octane fuel I got 27.6 mpg my last fill-up, mostly city driving, but some of my commute could be considered highway. Also have roof rack installed which might effect it a little also. Swapped out the fuel filter and am going to do an oil change before my next fill-up, so hopefully it will improve a smidge.

[jferreir]

I'm a bit disappointed with my fuel economy, too. Driving a 2012 Golf and I'm averaging between 500-550 km per tank in roughly 60/40 driving (hwy/city). I hit 260km with half a tank left (87), but I was driving like a senior.

Completely normal for mine as well. I try to hit 300 for half way then usually end with 520-550km at empty.

However I am having some amazing mileage since I put in the Carbonio intake. I got 710 KM on one of my tanks back from SoWo, all HWY driving though.

That 500-550km per tank is with the Carbonio intake.

What's most disappointing is that I've been babying the car, too. I'm talking 115km on the highway (with CC), and no sport mode. I might hit 130km every now and then, but I'm actively trying to drive slow and steady, and these are the results I'm getting.

My daily commute is about 55km roundtrip, most of which (75%) is highway. I tend to bike around the city, so my 40/60 (city/hwy) spread is also fairly forgiving. I'd say I'm averaging about 10L/100km, which is nowhere near the EPA rating of 9.1L/100km|6.5L/100km, especially considering the amount of highway driving that I do. What gives?

Edit:
Out of curiosity, how often do you guys check tire pressure? I'm a bit lazy, and I haven't checked it in 2 months or so.

[A1an]

I'm guilty of not checking my tire pressure as often as I should. If you are only doing it every two months you are probably running low most of the time.

[GTACanuck]

Yeah my one way trip is 52km from Newmarket to Toronto daily. I just installed the Carbonio before I left SoWo so time will tell how my mileage is.

I find that babying the car is not always the best for better mileage for some reason. It is truly weird. What did help me with my mileage, I purchased an app for my phone called Torque Pro (android) and a bluetooth OBDII dongle. This app has shown me the sweet spot on the peddle and calculate real time MPG L/100km etc... Its a very interesting app and with a total cost with the dongle and app it was under $30. It also does a whole lot more and I see it as a necessity for any gear head.

I have gotten into the habit of checking my air every weekend when I wash the car. I do have stretched tires and I have learned was happens to them if not properly inflated with camber

Gonna do a full fill up on Friday, I will track the results.

[thygreyt]

cars HAVE to be ran a lil hard every now and then.

driving like an old man can have serious bad effects:
-carbon build up on the cat
- dirty injectors
-dirty valves
etc.

its always good to keep the car at around 3k rpms for a couple mins. (per manual)

my car, in its 78k miles runs perfect. no build up, injectors work fine, i get 33 mpgs on the hwy and 27 on the city...

I use that for an excuse too

First post here on vortex*, but figured I'd add to the data pool: http://www.fuelly.com/driver/psn/jetta
Right now the car is bone-stock (aside from a Sebring antenna -- best $6.31 spent) and does a lot of highway commuting (70-75 mph).


* Super-fast intro: Grew up in LA and the first car I had was a '93 Passat GLX wagon (yes, a VR6!), then went many years without a car (college and grad school in the Northeast). Moved back to SoCal last fall and a few months ago picked up an '09 Jetta S, manual transmission of course.

[H3LVTCA]

I try to drive my Rabbit to the last drop of gasoline.
How far does everyone else go after the "fuel up!" light comes on the dashboard?

I thought I read somewhere that this light comes on when two gallons of gasoline is left in the tank, which means if the average MPG is ~25, we have ~50 miles to go before our car stalls.

[GTACanuck]

I barely can get 50KM after the light comes on, 5Litres ~ 1.32Gal (average 9.2L per 100KM and 27 Mpg). Although I have never had the testicular fortitude to see how far I can go until I run out


Might just pack up a jerry can and test this out one day

[cbs_24]

Would sea foaming the engine help with gas mileage? Anyone have a diy for the 2.5?

[DoDoubleGeo]

I'm getting a consistent 24-25 mpg, using 87 octane, driving about 10 miles per day, 80% city. I drive harder than I should considering I'm a dad in a wagon.

I think ive run mine out to about 65km but i was really babying it. and quite terrified at the end. Pretty sure i put 54.5L in it too when i filled up lol

[psn]

I provided my fuelly link, but forgot to put up some basic numbers. These days I'm getting ~29 mpg (generally 28-30) on 91 octane.

Slightly OT, but as a fellow dad (albeit in a sedan...not that the Sportwagen couldn't keep up), I believe that you should still have fun when you drive, just maybe at 8/10ths instead of 9 or 10/10ths. Last weekend I took my kid on a nice twisty road around here -- http://en.wikipedia.org/wiki/Angeles_Crest_Highway. He slept the whole time. (He's three months old.)

[rad5229]

Just went 403.5 miles with some fuel to spare. Filled up with 12.5 gallons. Pretty much all highway miles, but still around 32.3 mpg isn't bad. Cruise control with the speed between 65-70 the whole time

[A1an]

Do you guys suggest any injector/valve cleaner to run through these cars? I somewhat regularly used Redline fuel injector cleaner about every 30-40k on my past vehicles and it seemed to work well. I haven't done anything with this Rabbit yet but I'm thinking with 97k on it I should. My last fill up I only managed 26mpg and that was mainly highway driving.

The most I have ever put in was 52L, you must have really been running on fumes at that point

[phrog23]

84kmiles on car average 370-390 every tank. And if I drive from LA to PHX, some pulse n glide/ draft. 430.<- best tank ever..

Gas light comes on, I've gone 43 miles then filled up with 14.2gal.

I usually average 200 miles first half tank, doing good if I can hit 220, then @150 last half..

You wash your car every weekend? Damn, that's commitment! If you take the 404/DVP, my heart goes out to you.

So, I checked my tire pressure and I was slightly low on two (~0.5 PSI); probably not enough to make a big difference with respect to fuel economy. I honestly don't know how you guys are pulling those numbers without hypermiling, but I'm envious. In any event, I'm just going to ignore my gas bill and resume ripping it on weekends

Haha, had to look up that word..usually when I drive I'm not floored and I'll usually go 1,2,5... And if I can see there is a red light or something comming up throw it in neutral and coast.. Also if your on the freeway and comming up to your exit, bout a 1/2 mile coast it, and also down the off ramp.. And almost every down hill I'm on into neutral... My average freeway speed, 72..

Argh, why won't you silly Americans convert to metric already?

I don't throw it into neutral, but I take my foot off the gas and coast when I can. I normally limit my highway speed to 115kph (71.5mph), and use cruise control ~85% of the time. With the Carbonio intake, I'm still averaging between 500-550km per tank (310-340mi), and that's when I'm trying to conserve fuel. I noticed a plethora of mods in your sig. Maybe that accounts for the difference? I'm not a gearhead, and probably have the automotive know-how of a 12 year old girl.

Side note:
I absolutely, unequivocally, indubitably, frickin' love driving this car! I've owned it for about 4 months now, and I'm still excited to drive to work in the morning. That says it all...

That says it all...

I've owned mine 5 months (10K miles)
Sometimes I'll even take the long way to work, just to zip along for a few extra miles.

[Anile_eight]

I made it almost 730 km (453.6 miles) on my second tank from FL to PA. The first tank was just shy of 700 but this one should have more then 750 km (466 miles). I had a 15 min detour downtown DC, then I lost 35 minutes (verified by GPS) in traffic from Baltimore to Philadelphia. I put in 13.321 Gal which gives me 33.9 mpg (IN TRAFFIC AND CITY DETOURS!) so I was very very impressed!

[DUSlider]

Avg 32mpg over 1400 miles to/from SoWo this year. (Not including Tail of the Dragon shenanigans)

[Volund]

Some data to add

2008 2 Door 2.5L Rabbit auto-

Winter tires- usually around 25-27MPG driving between my house and my mom's (around 25 miles, mostly highway)
Summer tires- around 30-32MPG on the same road

I usually get right around 400 Miles/Tank in the summer

My rabbit is completely stock, except for a rear seat delete.

I've noticed that the rabbit likes to stay right around 65MPH cruising for best MPG

[Gunbu]

Got my best mpg so far coming down from North Hollywood to El Segundo (405).
Averaged 36.5 mpg.
I've had the carbonio on there for a few hundred miles now.
