Looks about right. I can usually get mine to hit ~31mpg with no AC, but only if I can keep it under 65mpg, so it's rare!

 

 

Just filled @ 31 US mpg / 7.587 L per 100 km / 37.23 imp gal.

It is a US market (vs German) version, so I am not sure how apples to apples they are. I am led to believe German versions normally get better mpg. A/C used most times and kept under 90 mph for this tank.

 

Not even broken in yet.



Someone had left my New Touareg idling for an awfully long time as it accumulated test drives before I bought it, as noticed by the long term MPG shown here at low MPG. Cruise control was only used briefly at 75MPH in an 80 MPH hour zone is a desolate part of Southern Utah on Interstate 15, only to accomplish the picture being taken. I rarely, if ever, drive this fast, only when forced to to prevent bottle necking, of traffic, it kills the MPG rather quickly on the Touareg... it's been noticed both on my 2012 TDI Sport, and this 2013 TDI Sport. Speed, headwinds and pushing air out of the way is the enemy of really good MPG per tank.

 

Dang niner, where did you pull off that 35 mpg over half a tank? Coming down out of the Sierras? I know I was able to get 34 between Tioga Flats and San Fran...

 

I'd last filled up in Beatty, NV, drove to Mammoth Lakes, loaded 'er up with 4 fatty's in their mid to late 50's, over 1100#'s of lard butts and went in to Yosemite, pretty far in, over Tioga Pass, went back to Lee Vining at Tioga Toomey's for dinner and live music, back to Mammoth Lakes, and then the next day started heading back to L.A. Probably was shot somewhere in the Owens Valley at 4000 ft elevation, higher in elevation than when I started at the last fillup in Beatty NV.

Drive them nice, slow down a bit, 60-65mph for me, being retired, is the sweet spot. I have lots of time, no rush to be anywhere. Lots less wind resistance at higher elevations to push and burn fuel on too... it's all cumulative and adds up, along with keeping that damn AC turned off. That will suck you for 2.5 to 3 mpg or more, easily.

No secrets, nothing special, any one can do it. The Touareg TDI Sport model with 18" wheels and the Goodyear LS 2's makes it easy for me.

 

I think that is probably one of the neater things about diesels. Once one is fairly comfortable about the parameters of TDI operations, it is easier or almost takes little effort to get pretty good mpg. For me anymore, given a set of fluid conditions and environments, it is fun to just guess what it is one actually gets.

Another thing that might take some doing to appreciate: I try to fill when the tank is fairly low. I have filled slightly after the low fuel lamp comes on, @ a bit past 23 gals/26.4 gal tank. So for example if I am posting 31 mpg, the range is app 713 miles to 806 miles.

The past post I filled @ 675 miles with 21.7 gals or 31 mpg (31.106 mpg)

 

I have a 2007 R5 TDI with 163HP, automatic gearbox, DPF deleted and have just under 10L/100km. Not bad but 8L/100km never happened to me.

 

B.V. Mine is same as yours but with Manual Transmission (which I like the best) and probably that explains this 8L/100KM I have. And I had to go through several mountains and uphills with a sick traffic otherwise I would have had it even lower, and surely below 7,5L/100KM

I had to crash the party because I love the whole fuel economy thing. This is a pic of me going to work usually I can average about 50 Imperial MPG, this is a trip of 90 km this time I went around and did mostly hwy. Not too shabby. I took it easy and just let it glide pretty much the whole way to work 1 hour. Usually I get what the video shows....that's much easier to attain. that's going through a bunch of traffic lights through the city about 20 minutes.

For those conversion challenged, the pic below is about 60 MPG imperial or 50 US mpg.

 

Nice

2011 Touareg TDI Fuel Economy - YouTube

That is awesome! I bow to the King of liters /100km. You are the Jedi of VW Touareg T3 TDI fuel consumption conservation, Master!

 

Yes there is an other explanation, I'm sure I can get the same value om my MFD
All you need is vagcom and adapt consumption value in your instrument cluster ;-)

Did you ever reached 2000km on a 100L tank? Then you have a wonder Treg ;-)

 

Exactly.. Real world figures are different.. Sometimes by mfd seems that I can do 1500-1600 km.. But that isn't possible.. 1180 is the max i can get

 

Oh and BTW, this will make golf and passat drivers very jelaous!

Not at all ! I'm just back from a trip with my 2012 Passt TDI from Montreal to Rivière-du-Loup and to Saguenay/Lac St-Jean and on the highway between Mtl an Riv-du Loup, my MFD give me an average of 3,9 L/100 km at 106 km/h (100 km/h on my GPS). I did fill up at Riv-du-L and fill up again near home. I did put 46,8 litres for 985 km (my tank contains 70 litres). Lots of hills and small back country roads in Saguenay region.

BTW, I'm sure that all of you know's where Rivière-du Loup and Saguenay/Lac St-Jean are located on a map...

I think I can safely say all of us do....Thanks Google!!

 

No modifications on the Vag com, and no I don't live on a hill just simply allowed the vehicle to glide along at 100 km/hr. There were a few lights in there too in the video.

Hey, I know where Rivière-du Loup is i'm driving past there in a couple days on my way to new Brunswick.

I find MFD is usually about 0.1-0.3litres per 100 km optimistic. So having said that it's still not bad.

 

The below picture shows my best milleage so far! It is true that one needs to avoid all missunderstandings here and reach the best ever mentioned of getting a 2000 KM out of a full tank of 100 Litres. My records are not matching this criteria so far but I will try to do that soon. I want to see if I can do it or how close to that I can get.

 

just did a trip from VA to AZ. 2250 miles. Lowest mpg was 22.4 highest was 26.7. Rolling just shy of 80 most of the way. Have noticed if I keep my foot off the skinny right pedal and do around 65, mileage is much higher. Does this trend with others?

Also, the low reading was from "suspect" source diesel. Does the quality of the fuel affect gas mileage?

100% quality of diesel will affect mileage, it will also affect longevity of your fuel system. Always remember to only fill up at high volume truck stop type fuel stations unless it's an emergency. It will net you better mileage and also protect your car.

 

I've run mine in many states, both the 2012 TDI and the 2013. Where you buy your fuel, geographically, makes a huge difference.

Nothing in my experience beats the fuel MPG, consistently, year after year, of the diesel fuel I buy in Arizona, Utah, Wyoming and Montana. I have the fuel logs to prove it. Every time I've bought fuel in Colorado, or anywhere in the Midwest, I lost 5 to 8% MPG over the fuel bought in UT or WY or AZ. It's my belief that the diesel fuel on those states is high in aromatic content, it's probably based on oil coming out of Wyoming oil fields, and it's really high in calorie count and completely suitable for being burned in a diesel motor at constant, steady state operation, like on the interstates for hour, after hour, after hour.

Getting 22.4 to 26.7 MPG, even at 80 MPH, is terrible. I did 75 MPH-80 all the way from L.A to Chicago last November, and averaged 32.5 to almost 34 MPG the whole trip, on cruise control. 2012 Touareg TDI Sport.

There's about 140k calories in a gallon of diesel fuel, and 129k calories in a gallon of biodiesel. Makes it physically impossible for the fuel to give you more MPG when it has less calories per gallon. Most folks report 8 to 10% less mpg per gallon, pencil and paper, running 100% biodiesel vs 100% D2 diesel fuel.

One needs to always pay attention to headwinds and tailwinds when computing their MPG per tank. Easier to do if you burn the tank of fuel in a day, versus over a week or two.

Now that I am in AZ, I guess I am looking forward to the fuel and getting better mileage. The MPG listed was hand calculated after each stop, filling up exactly the same way. Since the Treg kills the average MPG once you fill up, I need to remember what it indicated, since I seem not bright enough to remember to write it before I start the fill.

The computer was giving me consistently 1.5 to 2mpg more than my calculated amounts. I have seen a near 30mpg calculated run when I kept it below 65. I must say that I am happy with the mid 20's that I am getting, but if the rest of you are more than that, I need to figure out what the issues may be. The Treg has just over 22k miles now and I have a log of every fill up done. It is easy for me now to go back and get the summary.

Any tips for increasing mpg?

 

it's possible that the bio had more cetane additive causing it to burn more completely. But usually I would expect a decrease in MPG with Bio.

 

Cetane rating is a non issue with these common rail diesel motors with multiple pulse injection capability per burn cycle. It allows for complex injection timing cycles that the piezo sensors in your glow plugs that measure cylinder pressure pick up and feed back to the ECU in a closed loop control system, and the ECU compensates, timing wise, the injection, for the cetane rating of the fuel.

Cetane rating was more important when our old Bosch EDC-15 systems only had a pilot injection and main injection cycle. Even then a slight boost in cetane with Power Service Gray additive on a long highway trip was noticeable in the increase in MPG in my fuel fill up logs.

That has not been the case in my 2012 Passat TDI SE, or my 2012 Touareg TDI sport, or my 2013 TDI sport. Adding Power Service Gray and bumping my cetane 3 to 6 points has made zero difference in improvement of my MPG in any of them, none that I can discern from pencil and paper calculations. It made a nice 5 to 8% MPG improvement in my 2002 Jetta GLS TDI on long interstate trips where the motor was run in excess of 2200rpms, over the exact same roads, and nearly identical conditions. I saw this pretty consistently when going on long distance travel fly fishing trips. YMMV, these were my observations.

 

Check your tire pressures. In AZ, you're fine going a few pounds above spec, just keep it uniform side to side. Here in CA, my cold pressures are 35 front and 41 rear. It's nice to not worry about rain or snow. If you're up by flagstaff or somewhere where there is actual weather, it's probably not worth the very minor mpg gain to go over pressure. Ditto if it's super hot where you are, the wear on the tires won't be worth the modest gain.

Remove any excess weight you're dragging around. Figures vary, but I've typically seen about 1% worse fuel economy for every extra 50lbs quoted.

Keep the RPMs low. As fun as it is to floor it, going above about 3k isn't doing any favors for your drivetrain and fuel delivery systems, and it absolutely kills mileage. Try to accelerate smoothly every time. You'll find you can still be decently quick without slamming the gas down, and your tranny will learn the shift points and make it even quicker.

Keep it clean. At highway speeds, a dirty car is a bit less efficient than a clean one. If you've recently gone mudding, hose it down before you get on the interstate.

There's really no easy way to get good gas mileage. The driver is the single biggest variable every time. Just be mindful of your driving habits.

 

I'll go a couple steps further than cb62fcni.

Get 255-55-18 109xl rims and tires with an "H" speed rating.

Inflate to 3 or 4 psi cold over recommended air pressure.

Don't exceed 2000 rpm ever when accelerating, except once or twice a week getting on the freeway on ramp once the motor and drive train are completely warmed up.

Never stab the accelerator... instead slowly roll your foot into it when you need to accelerate, over a 3/4 to 1 second period.

You'll experience huge savings just by setting the cruise control at 70 mph for any trip under 200 miles... the time savings will not justify the added fuel expense if you are purely after MPG's.

log the fuel station locations and brand where you fuel up, and compare mpg by stations.

Turn your A/C as low as possible, fan level wise, to barely maintain a comfort level.

Be exceedingly frugal in your use of the brake pedal, plan ahead, look ahead, drive ahead, and don't be a red light or stop sign racer, when you can coast instead with your foot off the accelerator.

Conserve momentum at all cost, realize that brake dust is fuel and the energy it created being thrown away and lost, forever.

Go hang out on TDIClub.com for more pointers on diesels and improving MPG's in the economy, fuels and oil section.

It takes commitment and discipline to make the sacrifices necessary to get uber good MPG per tankful. Only you can decide if it's worth it.... To me, it is, but I am retired.

Most people never really learn good driving habits, they drive like lemmings or have a monkey see, monkey do attitude while driving, "because everyone else is doing it." That's the wrong attitude and conformist attitude kicking in. Dare to be different, smarter, more conservative than your fellow mindless drivers on public roads, and you will reap the benefits of your careful fuel consumption behavior.

 

Guys, you are killing me here. I am in love with the torque. Not really running it much above 2k on the tach, though I do have my moments. The off the line move for a truck of this size is great. (confession, my other car is a '69 912 that is now a 3.2L RS clone).

I will take the be careful advice into consideration.

 

This only in my observation... but folks that modify cars, seeking something else, or that race or build race cars that have more displacement, more HP, more torque, chipped, whatever the modification, that are not happy with stock.... Never see the MPG t that the folks that leave their diesels bone stock do, exception that I've seen is guys on TDIclub.com that spend the money to put in a 10% taller 5th gear.

That you modified a 69 porsche 912... all of the above for you will only be an exercise in consideration, nothing more. That's my guess, based on previous observations of folks, their sedans or SUV's and their modifications. You may be able to do it once, for MPG, but not repeatably. Doubtful you have the patience.
