800+ on a tank, whos with me.

[JettaJake]

my ALH mods never hurt mileage

My '03 ALH (aka Jake) CONSISTENTLY tops 50 mpg in summer (typical ~52 mpg) and rarely falls below 48 mpg in the worst of winter. A leaky tire and driving like I stole it ONCE resulted in mileage below 44 mpg BUT only for that one tank!! When I calculate a number like that (even with my oh-so limited math skills ), it's an immediate giveaway something's awry.

That's my "big lie" and you can stick THAT in your PD and suck on it .

And once more --- HELLO PEOPLE!! --- a ventectomy DOES NOT change how much fuel you can get into your tank. It only changes HOW FAST you can get fuel into the tank.

diesel on

I'm in @ 801 on 16.745 gallons of "B11" which is what one poster atop the pump says, but a blue and black sticker on the pump itself states that the bio blend can be anywhere between 6 an 20%. I use the same pump and all Summer I was averaging around 45.5mpg, but this last tank was just under 48. My LFL came on @ 639 miles and I carried a half gallon in the luggage compartment just in case. 1/8 of this tank was a 105 mile round trip through farm country and the rest was all urban with some highway miles as well. My car is an 05 Golf with an auto trans.
I'm still debating whether or not to have the steel GP with reflash performed.

I used to get 820+ out of my 99.5 Jetta. I hit a 1 ton truck with utility bed on it while sleeping with the cruise set at 65. They had stopped to turn left. I pushed them at least 20 feet. I got out of the passenger window and felt like superman not a scratch. Great car. but anyway. My 01 NB only gets about 730 to a tankfull. It is stock. Only mod on the jetta was a down pipe.

Screenshot from the phone app I use to track mileage. Fillup on 5/29 was for 812 miles... I guess if reports of the 17-gallon tank are true, and there were more diesel stations around here, I could pretty easily see an 850+ mile tank.

Most of the miles depicted are for my 34-mile-each-way weekday commute. It's about equal parts two lane and four lane, with a half-dozen stoplights, 400 foot elevation change, and a 700 foot hill thrown into the middle. I drive 65 (by stopwatch and milepost) on the freeway segment, which is about the 40th-percentile speed around here... I'm in the right lane except to pass, but not slowing anybody else down. My only antisocial traits are leaving a little more following distance ahead of me, and slowing down a little farther from redlights, than some of the Type-A characters around me might like... all with the goal of minimizing brake usage.

I could have artfully made all this data up, but... why would I bother? I didn't even bother to correct for my known 1.4% odometer error. (Reads a bit low, which means I actually went 1.4% further than the miles indicated in the screenshot.)

 

[tditom]

c'mon eddy- everyone knows that's impossible and you must have spent hours making up that data so you could brag on the internet...

Was your timing belt done on schedule, sir?

 

[EddyKilowatt]

Was your timing belt done on schedule, sir?

Nah... it was making some noise when I got the car at 65k, so I had it done (DbW again, at a Bay Area GTG) a few months later.

 

[EddyKilowatt]

In Red's defense, though, I will note that I myself have long advocated for some kind of informal steady-speed mileage measurement convention that we could all use to compare our TDI's mechanical performances.

It'd require a well calibrated ScanGauge, of course, but then all we'd need is something like a pair of steady-speed 65 mph runs, in opposite directions, on a couple miles of level road. Doing this would take both the driving technique and the speed, which are difficult or impossible to specify, out of the comparisons.

Those who have cars with problems would immediately be able to tell... and more importantly, everyone else would know how much they need to work on technique, or would be able to make intelligent decisions about lopping a few mph off their cruise speeds.

I think this would greatly reduce the frustration level that folks like Red, and many others (self included), feel when they check in here at TDIClub and read reports of 50, 55, 60 mpg performance. Those kinds of numbers ARE attainable in a TDI, but only by the minority of drivers willing to take increasingly extreme measures. Everyone else would be happy just to verify that their car is operating at mechanical norms, and then make their own decision about where on the mileage scale they wish to drive.

'Nuff said. My car gets about 49 mpg at a steady 65 mph on level ground.

806.9 miles, 16.23 gallons. I noticed one person mentioned that a ventectomy does not change how much one can fit in. I beg the differ. I always fill to the point where the "water line" is within 1/2" of the gas cap. I was never able to get more than 15 gallons in before venting.

 

[tditom]

the ventectomy does not change the tank capacity- it only makes it easier to fill it up. manually venting will allow just as much fuel into the tank. subtle difference, but it is accurate to say that the ventectomy does not increase capacity.

...as they say up east, ayuh! Time, not volume

Easy 800

52 mpg with vented on my way from CT to IN no prob, going the speed limit of course

 

[JohnBrock]

Hi all, another liar here. Filled up at my usual spot, drove to TDI Fest, drove around down there, came back and drove to work this week. Chickened out at 860.8. Went to the same place, everything the same except it was maybe 5 degrees warmer than when I filled up before. I got 15.7 gallons in for around 54.7 MPG. My personal best.

I was being careful, driving the speed limit most of the time and a little above the rest, air condo half the time. Nothing you would call extreme measures, unless driving the speed limit is extreme. 01 Jetta, 117,000 miles, stock engine.

Ok, you refer to "manually venting", I assume that refers to pushing the little flapper valve in the filler neck that we bastardize with the ventectomy procedure? Because without pushing it, I could not fit in nearly as much as I can now.

that is correct

 

[JettaJake]

812 miles & 52.12 mpg last tank while paying NO mind to mileage and only modest attention to the speed limit

'03 5M, ~120K miles, pp520s, RC3, 0.681 5th, DG down-pipe w/ cat-back, and vented (of course)

An alternative to the ventectomy or 'manual venting' is to fill up till auto click-off, bounce on the right rear bumper a few times, get under hood to check oil & coolant, check tires & tire pressure, clean windscreen & mirrors, and then spend your final ~2 minutes filling at flow rate slow enough to avoid heavy foaming. When you see foam-free fuel in the filler neck, you're done -- record odometer reading, reset trip meter - dieselGo!

My low fuel light went on today at 802.6 miles, does that count..?

How are you guys getting these huge amount of miles? Would it require the vehicle to be driven for more than 40k miles to achieve such numbers like that?

You're not going to see that in your '10, I'm afraid. I have a '00 and a '09. The '00 gets ~50 MPG in my 'normal' driving and the '09 gets ~42 MPG driving basically the same way. The '09 is a lot bigger, heavier, cleaner, and has a lot more power. All that stuff costs fuel.

Great job in that PD!! That rounds up to "only" 49.9 mpg

 

[scythefwd]

Fobulous,
Most of the guys you see doing this aren't driving above the speed limit. Most of us are also not driving PD cars and I don't think anyone has done it in a Common Rail yet (except for that one that set the mileage record for a mass produced car ... the 09 tdi at 67 miles to the gallon). My personal best is 53 mpg, and I was taking it very easy on acceleration, was moving 55 mph, and rarely touched the brakes as it was all open highway. I am surprised that my thread is still going strong after 2 years, but hey... it's all in good fun.

I won't be seeing this type of mileage again... my right front wheel well liner fell out, taking all the anchoring points with it (car is now even less aerodynamic). My transmission isn't what it used to be either. I have gotten my money out of her though, 120+ thousand miles since February 2006, and I only paid 8.5k for her. I'm just hoping to see 300-350k on the ticker before she dies.

 

[eric_TD]

I consistently get around 1150-1200 km (715-745 miles) per 55L (14.5 gal.)
so would that put me on the list...?

Also, my best tank was achieved a few years back on a trip to see family and I got 1379 km (856 miles) on 55L (14.5) and this was done before I got the mod bug.

No, the 715-745 won't get you on the list, but that 856 does

It is too bad they don't have something like this, http://www.tdiparts.com/catalog/product_info.php?cPath=99&products_id=1063, for a new beetle.

Brokk,
I still have the old fender liner.. I just don't have any place to mount it to! All of the little tabs that the liner screws to on the front clip were ripped off when the liner went. I am still trying to figure out how I ran over a piece of my liner while it was still attached to the fender. I might end up making a new mount for it by using an old strip of plastic screwed into the fender and then screwing through the liner and into the piece of plastic. I will probably need an expanding sleeve to do this with too.

Did it today for the first time in my life! 798.6 when the light came on and dinger rang...... then 812 miles for a 14.7 gal fillup. 55 mpg. , certainly beatable by many on here..... been enjoying my new Rocketchip #2 . Now I wonder if it's worth it trying for the 900 mile club????

More than just miles a ventectomy, lots of patience and willingness to drive long distances at 55 tops.

I got almost the same thing, 790something the low fuel light came on, went to 813.9 and 14.804 gallons. 54.97mpg

I am wondering the same about 900 miles. From what I've been reading I have another couple gallons I could be using X 50 mpg = easy 900 miles, but I'm scared to find out.

I think that the people that put up the big numbers tanks often carry a gallon or two of fuel with them and tools necessary to fill up the filter so that if they run out they can just top up the filter, pour the rest in the tank, and drive to a gas station.
