My best mileage ever was on a road trip from London, Ontario to Salem, Mass. I racked up 1,120 km (700 miles) and then needed 52 litres (13.8 gallons) to fill up. So the trip average was 50.7 mpg (or 4.6 litres/100 km). I wasn't hypermiling either. This is almost the exact same mileage that I used to get from my '05 Golf TDI, which obviously had a lot less power. Typically, I get 48 mpg or so when crusing at 75 to 80 mph.

I've never actually burned off a full tank in city-only driving. When in town, I'm always hammering the throttle. My best-guess estimate is 32 mpg city. I'm sure if I drove more sedately, I'd probably get at least 35 mpg.

Over the lifetime of my 2010 Golf TDI (12,000 km) my average fuel economy is 42 mpg (5.6 litres/100 km). I expect that will improve in time, especially if I get some mods going too.

Anyone think they have the high mpg on a tank with there jetta or golf 2.0 cr tdi?

Im looking for what the best mpg achiveable might be. I only have 1 tank on mine so im hoping after winter to go for a good couple tanks see if i can try and get close to my 03
I have observed that folks concerned with "best" mpg seem to bypass, over look, or just plain don't know about the monthly MPG "competition". Why this is so, I have not a clue, especially when the EXACT data one would probably be looking for is probably ... there. http://forums.tdiclub.com/showthread.php?t=298471, the last month's results with full cycle results IN.

So since you have an 09,10,11, MY, 6 speed manual, the posted range is between 58.47 to 40.92 mpg.

Some of these mileage figures are very impressive. Unfortunately, I have Los Angeles gridlock stop and go traffic. I figure it's about 80% just idling and stop and go and maybe 20% when the fricken freeway allows me to do 60-70 mph when it briefly opens up. I just broke 1000 miles on my odometer and after my 4th fill up the best I can muster is 34 mpg. I can't wait to be able to just go on a open highway with no traffic to see what she can do on a full tank.

For sure, there is not much you can do about those commute conditions (I am swagging here, correct me if I am wrong) . The only thing I can say is to know your VW owner's manual technical page and operate (execute) the best you can under your operating conditions. We do a very similar commute (27 miles one way) which can take, point A to point B, anywhere from 30 mins to 2 hours) and the range with a DSG is posted in the signature (40-47 mpg) and Nov 2010 mpg competition (3 drivers).

Yeah, my commute is 25 miles each way with some side trips at lunchtime. Actually I am happy with my mileage in this terrible L.A. traffic. As the engine breaks in I hope to see some better mileage figures. I do wish my little tdi had about 50 horsepower more, I may have to look into a flash from Malone someday :D.

I may be wrong, but lots of stop and go -- combined with the occasion stab up to 3,800 or 4,000 rpm -- is a pretty good way to break in your motor. I am fortunate enough to have mostly free-flowing highways around here, so when I was doing break-in, I had to maintain 75 mph while alternating between 5th and 6th in order to vary my engine speed.

At least you're not driving a large V6 or a V8. You'd probably be seeing single-digit mileage right now otherwise.

Yes, I also think that some stop and go driving as well as some freeway driving has helped my engine see a variety of RPM ranges to help in the break in. I also agree that I would definitely would have seen much lower MPG figures in a V-6 or V-8 under these conditions. Gotta love my little turbo diesel :D.

That's Excellent

I just turned 3200 miles on my car this week. Best/worst hand calculated tank was 45.6 and 40.4. My best single trip according to the MFD was 125 miles from my home in Big Bear to work in Century City that registered 61.7. This was from my house at 7000ft to near sea level.
My MPG on the MFD was 75MPG at the 45 mile mark of the trip when I got on the freeway.
The last 80 miles of freeway lowered it to 61.7. I'm quite happy with the car so far.
:)

That's excellent for coming down the mountain. Wait until it is completely broken in! :p

The question is: What kind of F E do you get going from Century City back up to Big Bear? :confused:

Another question: What kind of F E do you get for a R/T? :confused:

:D

Well most of the time I drive up the hill, I end up at my house with the MFD reading anywhere between 39 and 43. A lot of that depends on how bad the traffic is on the freeways on my way home. My lowest reading on the MFD was last night at 39 and traffic was really bad most of the entire way. I usually dont get any kind of round trip figures, but my best tank fill up is a tick over 45 hand calculated. I am going to be looking into a few different brand fuel stations to see if I can find a hotter fuel. Not that I think I have bad fuel, but just gonna try 2 other places for the next few fill ups to see if there is a difference.

Best tank yet? 2010 VW Golf TDI, 6MT, 830 miles, 14.85 gallons, 55.89 mpg. The wife refuses to ride when I'm hypermiling--it can be a bit irritating to other drivers.

Good commute, though, minimal stoppage, mostly highway, and favorable overrun conditions when stopping is needed.

Normal driving, I average around 47-48...

Wow. That's impressive. My best trip number was last summer, late at night on Interstate 65 between Gary and Indianapolis -- 100 miles at 59 mpg. BUT. . . . .the interstate was packed solid with semis so I stayed behind a big rig in the right hand lane at around 55 mph, drafting I'm sure. My best tank so far, hand calculated, is 47 mpg, which I got, oddly enough, last winter driving about 90% highway. I'm pretty sure I could break the 50 mpg barrier for a whole tank if I could exercise your patience and keep my speed down on a 600+ mile highway trip (I don't think my speed demon wife would go for it, though). I'm not sure that's ever going to happen because the longer I own this car the more I enjoy driving it hard.

Ain't That the Truth

Mine is exactly the same way.

If I'm not running at a true 80 mph, she is upset. I cannot
figure why she is in such a hurry all the time? :confused:

But at 60 mph (even the semis pass us and their speed is supposeded
to be 55 mph), she falls asleep and I motor on, happy as an old clam. :cool:
Let those that are running 85 mph or better keep the California Highway Patrol busy.

Did anyone ever figure the difference in seconds per mile between going 60 mph and 70 mph?
How many seconds do you save? And look at what it costs you in F E alone!

:D

Most of my highway trips are under 200 miles and I can tell you there doesn't seem to be much difference in arrival times between 65 mph and 70 but there is a definite improvement in fuel economy at 65 mph. The nice thing about Indiana is the speed limit for trucks is 65 and the interstates are crowded with them so it's easy to tuck over into the right hand lane and chill out. Ohio has a speed limit of 65 for cars on their interstates, so my mileage always improves on trips through the Buckeye State (and I believe their State Troopers do only traffic enforcement so they are everywhere). . . . .It's difficult to travel any distance on the interstates around here at a sustained high speed because there's always someone in the left hand lane going slowly, or trucks passing (they must have governors set at 65) blocking traffic. It's all speed up, set cruise, slam on the brakes. Sometimes it's just easier to slow down a bit.

That's what I cannot get my wife to comprehend. :(

It is all but impossible to get many people, especially the younger folks to understand that.

Driving at 70 miles per hour, we find that is takes 51.43 seconds to cover a mile.

Driving at 65 MPH, we find that figure to be 55.38 to cover the mile.

So the difference is on 3.956 or less than four (4) seconds!

So if you are traveling 65 mph instead of 70 mph, you will save a whole 13.8
minutes
over 200 miles. Big deal! But look at your savings in fuel economy.

Easily figured by using the constant 3600 divided by either mph or seconds to travel the mile.

What could be easier? :confused:

My commute is 36 miles each way including 24 miles of 70mph and stop and go highway.
My first 2 tanks averaged 39.8 when doing the math at the pumps. I am very happy with the results so far and expect better results once the engine breaks in some more.

Don't know what's wrong with me or my car but I have a 2010 Jetta 6mt and my best tankful has never broken 600mi. 15,000 on it and 37mpg is about average for about 70 highway 30 city.

Some of you guys get awesome fuel economy... My best tank is about 540 miles/14 gallons. Highway at 70mph with the cruise set. I have averaged about 36hwy for the 11000 miles I have had it, but I get 36-39 commuting. Dont make sense!

Be sure yo break your car in right. This can be found here: http://forums.tdiclub.com/showthread.php?t=252501&highlight=2009+engine+break

You also have a JSW, which gets 3-5MPG less then Jetta Sedan TDI (In my uninformed opinion... based on weight assumption and people posting their results here.)

Also, don't cruise. Worse gas mileage. Have a light happy foot. Don't go 70MPH, go 60-65... light on accelerator when accelerating.

On a side note, I wonder how bad your fuel economy will be if you drive in DSG Sport mode all the time...

My 09 Jetta now has 92,000 miles on it. The best it has ever done is 42 MPG. It seams 62 MPH is the sweet spot anything more than this and it drops. I can say when i use Power Service the mileage increases but i only use it once a month.

It also might prove helpful if you can post what rpm your engine is turning when you go 62 mph.

Not So

You also have a JSW, which gets 3-5 MPG [?] less then Jetta Sedan TDI (In my uninformed opinion . . based on weight assumption and people posting their results here.)

Evidently you have not viewed my Fuelly!

The sedans and the wagon are listed as weighing the same!

Of course, those with the DSG will weigh slightly more. :p

Best tank mileage has been 44. Have seen as high as about 54 on short highway trips. Haven't really made a long trip since the new module was put in and programmed at 10k. We plan to travel to Florida (from here in Va) in early Feb to a wedding.

:)

And yours is a Manual 6 MT.
Try slowing down just a little to no more than 60 mph and stop using
Bio. and see if you do not get some improvement in F E?
Using both XPD and Bio., especially 10 percent is overkill IMHO.

Even though you have a DSG, you should be doing slightly better than a best of only 42 MPG.
At a true 60 MPH, you will be turning exactly 1934 rpms if you
have the standard 16 inch wheels with stock sized tires?

That is right near the top of your 'sweet spot'. Going faster than that will hurt your F E.

Find a level road in the daytime. No A/C and no seat heaters.
Get up to just a little over 1600 rpms (1611) and reset the MFD1 after you reach
that speed of fifty (50) MPH and see what kind of readings you will be getting.
I think you will be surprised. :p

Under good conditions (no wind, no rain/snow/with warmer temps) my '09 with DSG averages around 50 mpg when I set my cruise control with the tach at 2100 rpm. I've made the 160 mile trip on 1-65/1-94 between Indy and my home town in northern Indiana dozens of times and averaged as high as 52 mpg both there, and back. That rpm is about 65 mph (I got a GPS recently and discovered my speedo is slightly slow so that number may not be exact), fast enough to stay with the trucks in the slow lane yet not get run over. The terrain for the trip is fairly flat, but not completely, with some rolling hills in places, but what folks in other locales would certainly think of as Midwestern "flatland". In the summer/fall of 2009, before re-locating to Indy to be with my new bride (and driving mostly highway) I had ten tanks in a row that averaged 46 mpg (hand calculated of course). I live in the city now so I'm happy when I average 40 mpg for a tank, which I often do (38 mpg lately with snow and winter blend), driving almost all city miles (I make good use of the freeway system to avoid stop and go). I will say, for some reason, my car has gotten good fuel economy from day one, much better than I expected when reading the EPA numbers. With over 36K on the odometer, it averages 47 mpg at 70 mph under good conditions. I've noticed quite a few other members getting this range, and some who get a lot less. I still think there must be unknown mechanical/software variations between individual cars that result in good or poor fuel economy. However, just like everyone else, I get crappy mileage on short trips, especially now that the frigid weather is here and my car is loaded with snow and ice. I'm a long distance runner and I try to run most every day in a park three miles away -- I also take my Jetta out on the freeway most days and let it warm up, giving it a workout before mine, so it rarely gets driven just down the block and back. I'm fortunate because I have the time to do this, and I live in a good location near an interstate and beltway. But I can see how people living in a large, congested megaplex who only drive in stop and go/mall sprawl traffic would get crappy mileage out of one of these long distance thoroughbreds.
