Your V8 does have two filters and good luck trying to improve the mpg much more then what you are currently getting.

 

Yea, I get about the same and have for six years. There are 2 air filters and the one on the passenger side is a little difficult to remove, just be patient. Good luck.

 

Regarding air suspension setting it depends a little on the street conditions. I don't think fuel economy is affected much, though. I usually use "comfort" on bad road and "auto" for every day use. On the highway, I use "sport", since it lowers the car a bit and gives me better handling. It might use a little less gas in this mode as well, but if there is a difference, it is very small...

 

that sounds pretty good, i am getting about 16l/100km which is around 15mpg mixed city/highway.

i didn't notice any difference when putting the air-suspension in sport mode on the highway as far as fuel consumption is concerned.

 

Right now I'm averaging 14-15 per tank. Last tank was 14.8, highway indicates anywhere from 15-17 depending on cruising situations. This thing enjoys its drink, and its drink is fuel!

 

Some more stats. http://www.clubtouareg.com/forums/f43/how-far-are-you-going-with-your-tank-25983.html

 

Run it downhill - preferably with a tailwind - and keep unnecessary junk out of the trunk, don't carry lots of passengers, keep it waxed and make sure your tires are properly inflated.

If you do ALL of those, you can expect the mileage you're currently getting to increase by .00125 MPG.

I suspect I'd see mileage increases if I stayed off the interstates and cruised back roads at 55 - 60 mph...but the real fun in a V8 Touareg on the highway is found between 74 and 82 mph. It likes to cruise there around 2900 rpms. Expect 15-16 mpg overall.

 

Now if you had held out for a V10, you could average 24 mpg overall and over 30mpg at a steady 50 mph.

 

To the defence of us lesser V8 drivers, I thought about the holding out thing, until of course some simple mathematics had to be equated, adding my lifestyle to the formula of course, along with the price premium of buying the TDI on asking prices. With the amount of driving that I now do, it will take me aprrox 7.5 years of burning 91 Octane Super Unleaded fuel, to eventiually cancel out the savings that the V10TDI would have provided me.

That is a lot of super unleaded

Of course, not to misinform others, and stray them off, I iterate again, this formula includes the amount of driving that I do, and the asking prices of both the V8 and V10 in our market.

 

I currently get about 13.5-15.5 mpg with mostly city driving and a little highway thrown in for good measure. I used to get a bit better mileage but this past winter our gas stations switched from a part-time ethanol (up to 10%) mix to full time ethanol mix everywhere. On the other hand if I take a highway cruise and I (ahem) may get a bit judicious with the throttle (including triple digit speeds :-D) I can still expect to see 15-17 mpg for the trip. Not too shabby for a 5500 pound all wheel drive truck (though I still call it a car too). And for those who don't play with their air suspensions, or read the manual, it automatically lowers the car to sport mode and turns on all the regular headlights when you go over 88mph. Happy driving.

 

steady 50 mph

Im sorry but I there is no way I can drive my v10 at steady 50 mph on the hiway.
I took a trip last weekend , got about 21-22 mpg at 80 mph.
Driving in traffic to & from work it gets 17.5 mpg.
I have a hard staying below 80 mph.

 

that's interesting. I wonder if the one here has something wrong or too much biofuel or filter issues?

 

I believe him on that high mpg figure. Most vehicles burn significantly less if you keep it at 90km/h and not 1 figure over. Just the way the Physics is. Question is who has the patience to drive so damned slow.

 

I believe him on that high mpg figure. Most vehicles burn significantly less if you keep it at 90km/h and less. Wind resistance is the dominant factor when traveling faster than those speeds. There are exceptions to the rule, gearing, etc playing a role, but all in all, I can easily see how under optimum conditions, low resistance tires, maximum psi inflation, good quaity fuel, etc, that V10 TDI can reach that. Hell, I see an incredible difference when I cruise control my V8 at 50mph.

Combined on the V8 around 16mpg.

Not to bad guys, sometimes I wish I went with the TDI, but I can get around 16 MPG if I keep my foot out of it! LOL

 

On my first road trip this week end (write up to come) I averaged 19 mpg and thats at 75 to 80 mph the whole time.

 

I just did an 1800 mile trip and I would say I averaged around 17.9 and although I was on cruise control 95% of the time, it was set above 80 almost always. And boy was it a fun ride! I love my Reg!

 

It is helpful to either list your vehicle in the post or your signature...

 

Isn't that covered with the info on the Left?

 

duh, my fault, yes it is. I hardly ever see cars listed there.

 

Hah, and I just figured out how to get a pic displayed too. Gotta love it!

 

what about the 3.2l or 3.6l V6

 

Since I bought my 2004 V10 15 months ago.

19,677.8 miles : 944.6 gallons : 20.83 mpg : best - 24.86 MPG : Worst 16.12 MPG.

Interesting, the best was the first tank we burned which included a trip to the summit of Pikes peak. The worst was towing the racecar on an open trailer in the Sacramento Valley into a headwind at about 62 MPH.

johnt

 

just drove from houston to aspen and back.

got 16.5 on the way there

got 18.7 on the way back....elevation?

went 80-90mph going both directions.

 

16.9 on the V8 using the Tiptronic 100% of the time, but since temps are now nearing -40F that has something to do with it. Don't know about the CFO's V6 must check when she's not looking...

I've got 3.2 V6 with some big tires, and get about 15 in town, 18-19 on the highway. I suppose I could get better mileage, but I don't really care. If I want lots of MPGs I'll drive my Jetta.
