Pretty much my typical commute route, but keeping my speed under control and using some moderate hypermiling methods. Mainly trying to time lights, and minimize my throttle (and changes) going over the hills typically working to keep the speed between 50-60mph as I go up and down over the rolling hills on my route.

Finished up the tank with 800+miles and a fuelly MPG of 55.7mpg.
10 miles left according to the computer, and the emergency reserve beyond that.
To dead empty, I could have probably gotten about 850 miles. But with no extra fuel, didn't want to try it, nor put the fuel pumps through that.



A lot of fun, but you have to work the road and avoid the cruise control. I seem to pick up about 5mpg or more staying off cruise control unless the road is almost perfectly level or with very long grades (ie interstate).

Oh, and FYI, that includes one leg (about 92 miles) with the AC running on low. Massive humidity that day, it was a killer. Also this is round trip filling up at the same station I started at. IOW, it wasn't all downhill. :)
My 704 tank was a trip from Greenville, SC to Roanoke, VA with no A/C and running 5 over the speed limit all the way there (mostly 70 MPH). The first leg of my return trip my GPS took me over the mountains on Rt 221 for an hour and a half, which killed my economy for that part of the trip. The rest of the trip home was Interstate at the speed limit. I finished the tank off with a trip I normally get good economy on running 55 - 60 for most of the trip. In town and A/C use make a dramatic drop in economy for my car.....

If you could have kept it up Nick, you might have been able to pull 800 miles from that tank since you should have had about 2.5 gallons left in the tank. Of course, you would have had to dip into the emergency reserve (which seems to be about 0.8 gallons on my car) and push close to dead empty. Good luck on your next run. :)
My next goal is 800 miles and 55+ MPG.... I am in outside sales, some days are all short trips with traffic and in town stop and go. I will find another long haul to get to my goal, I just don't know when yet. :)

Finally made this today. Like 715 miles or somthin. Yes it was vented. I could have made this tons of times before but it never lined up with my driving that I would arrive at a station at just a little over 700 and I didnt want to push it and run out.

Anyway its awsome....

Motor on

Well.........unfortunately, I'm not going to be a member if this club on my first tank with my new waggy. Because, unless the gauge is broke or starts dropping allot faster soon, I'm blowing past the 700mi. mark into the 800's, and possibly even get into the ever elusive 900mi club. @ 410mi now and just half way between 3/4 and 5/8 full.

The gauge is not linear. But congratulations on your new car :)

I know its not.........I've read and researched this to death since posting a separate thread asking the question. And like I said, unless its broken........500mi. By the half tank is a excellent indicator of a high mpg fill regardless of make + model + year of TDI. Nowhere have I read anything to this effect:

"I thought I was getting amazing fuel mileage cause my gauge read 500mI. at the halfway point and dropped like a rock from there, now I'm on empty at just 600mi."

Knoxville to Orlando. I had to drive down a side street... and then went off roading when it turned out said road kind of just ended... so I could break 700 miles before rolling into the gas station.

Just had my first 700-mile tank today!

Tire pressure at window-sticker spec. A/C on for the whole trip. The gauge showed 1/16 left and the MFD said 40 more miles before empty.

Mostly highway miles, from southern MD to NYC and back. On the way up, I hit bad traffic in NYC and didn't make it past 2nd gear for 90 minutes! If it weren't for that, I'm sure I would have done better. No traffic on the way down, and the avg MPG went up nicely.

But, still, hit 700 on the nose (after driving around the block before hitting the gas station :D).

And this was only my fourth tank in my new Jetta! Very impressed with this car and so glad I got it!

Finally made it

Finally made it into the club
705 miles when low fuel light came on
Drove 755 until fill up
15.772 gallons on a vented tank
47.9 mpg average

I would really like to get into the 700 club with an unvented tank.

It can be done. Just have to work somewhat on your hypermile technique. Which does NOT have to be so extreme that it holds up traffic. You just have to work the road and keep your attention well done the road so you can predict what you're going to need to do before you get there.

It was surprisingly easy. Granted, that (unvented) tank I did it on was 80% highway miles. I set the cruise for speed limit + 5 and kept the A/C on. And I got 700.

I could go slower yet, I figure, and turn off the A/C, mess with tire pressures, etc., but I like the A/C and I like my cruising speeds.

The car just continues to impress me.

I am now thinking that I could get 800 in a tank with all highway miles. Dunno. Maybe that's pushing it ;)

I made this without much fanfare, and with over an 1/8 tank left, will make it deep into the 800 club. Just doubt I have enough to make 900mi.

I'm hoping to clear 700 this tank, currently have about 570 and the car is telling me I should make it to about 740......

Can't say for the newer gen's but it's no big deal in a MkIV Golf/Jetta with working EGR.
Not a guarantee but easy to do if you can manage to sustain 45-65mph consistently.
The secret seems to be totally filling the 17.x gallon tank by venting foamless to the top.

I do nearly all highway commuting at steady posted speeds with the occasional fast food stop or in-town errand along the way and 700miles on an almost stock '01 ALH (PP520's) at 70mph interstate occasionally escapes me but is usually no big deal with a/c on and cruise set the whole time with manually vented fill-ups just driving normal with the occasional hard launch from a stop or full throttle pass attempt on the freeway along the way...
Low Fuel light typically anywhere between 635 and 680 miles depending on my aggressiveness and the little drive-thru stops in the mix along the way.

In my early TDI days this past spring I would occasionally see the fuel light at under 600 miles and getting mid to upper 600's with around 16.3-16.7 gallon fill-ups was usually a stretch but I backed down from 75-80mph indicated to 65-70 indicated and it made a pretty big difference.

For example, I did the a/c off and 60mph (indicated) cruising thing for an entire tank a couple times and touched just under 700 before seeing the light the first time and crossed it the second time before seeing the light but haven't been quite confident enough yet to try for an 800 tank, as much as I'd love to achieve that goal someday, and I've sped back up to posted speeds as my work commute feels like it's taking FOREVER with the 10-15mph slower speeds...

I'm LOVING the cooler weather for not needing the a/c as I'm consistently seeing 3-4mpg's better without it with the same driving habits and speeds in the same car, rarely see the fuel light appear below 675 miles in this weather so far.

Had a defunct thermostat in this car when I got it and left it that way for quite a while so it rarely got up to proper temp without a/c on and agressive freeway driving in the HOT southern summer heat and I was quite a bit disappointed that replacing that bad thermostat and seeing 193c consistently on my ScanGauge since then didn't really make a noticeable economy difference overall. Same fuel light miles and gallons pumped before and after the replacement with same speeds/habits, i.e. I've never gotten any higher mileage since the replacement than before and as I change speeds and aggressiveness I still see the same range I expect from the tank with such behaviors every time so far after the replacement as I did before. That's not to say that it didn't help a little but I'm not seeing the big improvement I was all geared up to expect from what people were saying...

I'm told that I'm getting "within stock economy specs but on the low end of the range" and that an intake/manifold cleaning and timing check will help a lot. Fingers crossed for when I get a chance to do that, hopefully soon...

On my second '01 5-Speed Jetta GLS TDI this year and seeing very comparable results as the first one with 100k less miles on it this time... Ventectomy on the first one, manually vent and slow pump the second one every time. Ventectomy or manual venting makes a BIG difference in range but has no effect on actual economy.

2001 Jetta 5-Speed, my experience so far, manually vented for a truly full tank...
A/C on, 75+mph all highway, 700 miles takes a bit of work, thought, patience, guts.
A/C off, 70mph all highway, 700 miles is no big deal to achieve effortlessly... (on a truly full tank)

been there a couple of more times. can get there easy now, just need to keep speeds reasonable.

ultragauge showed i had 30 more miles left on the tank but fuel light came on and didn't want to push the luck and was showing 49 mpg and that's what was calculated.

760 miles on this tank! Sweet! I commute 125 miles each way to work everyday, and have been working to get my mileage up. Made it to 51 mpg this last tank. Loving my TDI!

Finally kept my foot out of it long enough to get a 700 tank. Comprised of 400 highway and 300 city miles and running 37psi on Michelin MXVIV's. My city miles are primarily short 2 - 10 mile trips so best case it barely has a chance to warm-up and it's time to shut her down which I know is rough on economy. I have close to an 800 mile road trip next week and will shoot for an 800 tank. Prior to the road trip I plan on adjusting my IQ back to 4 to 4.5 as I tweaked it for power a while back and suspect that's costing me some mpg's. May bump my tire pressure up a bit too, but the ride gets pretty rough with those bilstein's. Utilizing overrun and pulsing seems to be helpful.

701 Miles on 16.11 gallons of B20

I'd be happy to get 600, I think my gas gauge is poorly calibrated as I've never been able to put more than 14.6 gallons in the tank. I'd like to push it a bit but I really don't want to risk running the tank dry.

I love to stretch my miles as much as the next guy, but I have an older pre-HPFP version. I cringe when I see people with the in-tank HPFP try to squeeze every mile they can out of their tanks. Just a few seconds of running that pump dry will (may?) ruin it. Personally, I would fill it at a quarter tank and be happy with a 500 mile range.

The HPFP is not in-tank. An in-tank low-pressure lift pump feeds the HPFP that is driven by the cam belt. And while I can't even pretend to be an expert, I have read that the computer will shut things down if the tank goes dry prior to the HPFP going dry. If the tank goes dry, there's still plenty of fuel in the filter housing to prevent a dry HPFP.

Data points: Our 2012 Golf has 18,000+ miles on it and I have averaged 13.1 gallons per fill up. Our 2009 Golf (was Jetta) SportWagen averaged 12.7 gallons per fill until I stopped tracking at 76,000 miles. It's at 81,000+ now. I can't imply anything with those numbers; they're just data points. I may have future HPFP failures or I may not.

Which is not to say that running the tank to 'dry' is a good thing particularly if done several times.

@AusIndr ECM is not smart enough to stop if you run low on fuel. But it will shut down if the fuel pressure drops low enough.

It has never been a smart idea to run low on fuel with electric in tank fuel pumps. Being submersed in fuel with a strong flow of fuel is their cooling and lubrication. We learned this the hard way with a F250 and dual tanks. Dad used to alway run it dry then switch over like he had with the older Chevy (mechanical pump). But he stopped that habit when he managed to burn the fuel pumps up.

Back to the thread - I put the stock 15" alloys back on and I am tracking to make 750 miles this tank.

Had my first 700 mile tank. I have been close before, but always had to fill up before I got there due to location/timing/etc. Was at 701.0 miles today when I pulled into the gas station. Took 14.81 gallons to fill up, so I should have had another 1.2-1.7 gallons left in the tank. I couldn't risk running it further down with my commute (55 miles each way). 47.3mpg for that tank is my best other than a 49+ outlier where I fueled up just a few miles into a tank.

I made 68+mpg on the way to the office today thanks to a car hauler through part of my commute who basically pulled me behind him from all the wake he was creating.

If you've removed the vent and fill up to the neck with clear fuel you had over 2 gallons left. Most I've ever put in my wagon is 17.1. Done 16.8 or 16.9 a couple of times.

I did 725.1 miles on 15.04 gallons driving from Lacombe, Alberta to Pasco, Washington In October. I used cruise control for almost all of it. The cruise was set to about 10% over whatever the posted limits were. I used the A/C a little (maybe 100 miles or so).
