I've so far only burned through 2.5 tanks of gas on my new Stelvio, but both times it's gotten down to 1/4 tank on the gauge the low fuel light comes on, and a fill up takes about 15 gal.

Anyone else seeing similar issues? Want to get an idea if it's a broken sensor or what may be going on before I call the dealer.

Forgot to add, I've struggled to get above high teens in my MPG with normal driving. Now I know I can have a heavy foot sometimes, but I'm driving it the same or even easier (due to the still low miles) than I drove my Evoque, which I never had a problem getting at least 24mpg.

Same for me, yellow light same position same petrol quantity.

2,000 miles on clock of my fantastic car averaging 23.5 mpg in UK Our Gallons are larger than US

Interesting, I've never heard of a UK gallon that is larger than the gallon unit of measure that came to the US from the UK. Perhaps you are thinking liter used by everyone outside the US and UK?

Anyhow, I have about 1600 mi on my Stelvio and, assuming the computer is correctly calculating, I am averaging somewhere between 22 and 23 mpg. I do most of my driving in N with occasional stints in D. I used A for a couple days thinking maybe I would save a few gallons eventually but then I remembered why I bought the car. In an interesting side note, I had to take my young daughter somewhere last night and she disappeared when it was time to go putting us behind the clock to get there. I was a little mad when we left the house but MAN, that ended up being a fun ride. Still wound up arriving 1 minute late but let's just say I made up some serious time!

The UK (or imperial) gallon is 4.55 litres, about 20% larger than the US gallon which is about 3.79 litres.

that's 22-23 US MPG?

I only just rolled over 600mi, but I'm struggling to average 15 MPG driving essentially the same way as with the Evoque, where I was getting 24-26 MPG. I expected 3-5 MPG lower with the Stelvio, but not down in the 13-15 mpg range!

Yes, US gallons. Something doesn't seem right. Are you using high octane fuel with 10% or less ethanol?

 

[SailDrive]

Yes, though I can't say for sure it's 10% or less, as non ethanol fuel is actually illegal in Connecticut. Most of the pumps claim to be 10% :crying

 

[PatD]

Have you been using premium fuel? Is the ethanol included in premium gas or just the regular unleaded? I have a little over 800 miles on my vehicle and so far have been averaging about 21.5 miles per gallon

 

[SailDrive]

can't say what the dealer filled it with since it was full when I picked it up, but in the ~650 miles since then I've filled up twice with premium 93 octane, and going to have to fill up again in the next ~75 miles.

I do the majority of driving around town, but I've only been getting about 14mpg! I can barely even get 21mpg average driving down the highway with cruise control on.

 

[TiSport]

Strange - I've been doing a fair amount of city driving, and stepping on the gas pedal a bit (a bunch), and my 2018 Ti Sport is showing avg mpg of 21.1 and speed of 27, so a lot of Christmas type driving, and short trips to take my wife to work as she was waiting for her new Porsche to be set up...

So I expected something like what I'm getting with the way I've been driving... When out on the road, the Stelvio cruising MPG (second center screen) was showing about the same mileage as I was getting in my Mazda 3GT.

So something seems quite wrong about what you are seeing...

 

[zvezdah1]

something not right, there, I'm getting around 22mpg around town driving in dynamic mode.

[Scalewoodman]

Agreed: worst I got was 22.7 heading into gusts and currently in bitter cold. Best 31 mpg 93 octane.

The tank takes only 16.9 gallons. If you put 15 in, it only had 1.9 left. Modern cars should not be taken much closer to empty to prevent the pump gulping air in the tank. Next time, since you are getting 24 mpg, try driving another 24 miles to use up another gallon before filling it. This way you can find out if the 1/8 mark lights on time and exactly how much is left at that point.

 

[SailDrive]

I've now got 2200 miles on the car (took a road trip to Vermont for Christmas and the Poconos for New Years), and highway I've averaging around 22ish. Around town I am still seeing ~17, but better than the ~14 I was getting before the fuel pump issue. I swear my foot isn't THAT heavy!

Last night I filled up at just under "1/2" on the gauge, and it took 14.8 gallons....

 

[zvezdah1]

but the tank only holds 16.9 gallons.

yup, now you're understanding why I said something was wrong with the gauge!

I need to get it back to the dealer for this, but so far I've never been able to get the gauge below 1/4 tank, and when it reads 1/4, it takes over 15 gallons to fill up.

 

[ARS]

I don't expect superb accuracy from gauges that read in "bars". I just try to learn them. The gauge had just turned from "3/8" to "1/4" at the last fill up. It took 13.745 USG. So, 3.1 USG (19%) left.

that's not that far from what I'm seeing. around town I start thinking about when it'll be easy or convenient to fill up at one bar above 1/4, and try to fill up before it drops to the bar below 1/4, pretty much all my fill-ups have been 15.x gallons in those cases.
