I am only on my 3rd tank so I lack enough sample data to come to a solid conclusion. However I do know compare to my 11 2.0T? MY GOODNESS it uses WAY less amount of fuel! On the 2.0T, under same conditions I can get AT THE MOST 450 miles per tank. With the TDI? I haven't even receive the refuel notice I have over 550 miles on it.

Glad I made my decision to trade in for a TDI. So much more POWER yet uses less fuel.

Oh and... diesel costs less than Premium in SoCal now lol.

NABS4 said "I'll take solace in the fact that it will take you 70k mi to make up fuel economy difference for the premium you paid for the TDI."

Why do non-TDI buyers assume people buy a diesel for the gas mileage? I never hear anyone say "Well, Bob you're going to spend $4,000 dollars more in gas since you bought that Camaro" yet when diesel or hybrid is mentioned, they automatically go to "It'll take you "X" years to recoup your savings …"

Maybe they bought the TDI because they liked it better.

I've averaged 26.0 MPG over this 10k miles. I've gotten over 30 MPG on segments, but I love the torque and am having a blast making full use of it. And to do that and still get 26 MPG, I couldn't be happier. It's better than any of my other cars listed in the graph below for MPG and bigger than all of them, and quicker than some. It's just plain fun all around and meets all sorts of different needs of mine (utilitarian). I know others are getting better MPG, but they're clearly not having as much fun as I am




Zoomed in for just the Q5 TDI:



I changed the VAGCOM fuel consumption accuracy to "108" and that looks like the perfect setting (based on first 2 datapoints and trend from 110/109 settings). Now I can trust whatever I see on my trip computer to be accurate. That's awesome we have this ability:




Have been getting around 500 miles per tank (median value) and quite happy with that too:




I ran out of fuel this morning when I was pushing it. I got 33 miles past empty and had been driving rather efficiently since 0, averaging around 30 MPG, so just about a gallon of spare capacity. This was over 2 days, with various stops, so I likely could have gone further if in a single stint. I'm happy to know the limit and now I'll stay well within it . I hope you all benefit from this . When I ran out, I actually tried starting it a few times to get me to move just a little, getting me out of the lane I was in to a safe place. Then upon filling the car with 1 gallon of diesel, when I went to restart, it cranked for a while (5 seconds maybe, seemed forever) and then started up just fine.

I put 1.051 gallons in a can and into the car, then drove 7.5 miles to a gas station and proceeded to add 19.978 gallons. This tank averaged 24.4 mpg, so if I apply that to those 7.5 miles, I consumed 0.307 gallons during that drive, meaning I still had 0.744 gallons in tank. Adding the 19.978 until the pump shut off means the tank took ~20.7 gallons from dry to pump shut-off. FYI for those who may find this interesting.

All TDI owners should get their hands on a Fueling Adapter. This is needed to pour fuel in from a can or from a non-standard-diesel pump nozzle. The diesel pump nozzle is wider than a gas nozzle, which prevents putting a diesel nozzle into a gas car. But there's also a mechanism to prevent putting a smaller gas nozzle into a diesel car (at least the Q5) and that's a release on the flapper that requires the nozzle to be full (diesel) size else it will not open. So this full-diesel-size plastic funnel performs that task:

Part Number: 000-072-709 Looks like List Price $8.70 at VW & Audi Dealers. I'd suggest a VW dealer as they often have prices less than MSRP. Below is a good online Audi Dealer with it for $7.40, but of course have to add ship. Check your local VW and Audi dealers for online parts pages to see if they list reduced prices online, or call and see if they have standard price reductions (ie 10%) from MSRP. It's worth trying a few as I've found quite the variation in local dealerships.










And I've been driving this a whole heck of a lot more than my 911. Partially because it was over winter, partially because I've given more attention to the new car, and partially because we're taking my Q5 instead of my wife's Tiguan whenever we go out as a family (including 2 trips up north, evident in the graph)...



In comparison, when I first got my A3 and drove it 10k miles, I drove the 911 3k miles, 3x more than I've driven the 911 now: (no kids then)




and when I first bought the 911, I drove it much more than either my S4 or Golf (or the sum of those):



All signs pointing to the fact I am really enjoying the TDI Q5
