Wow! Assuming you have not just bought a new pair of lead boots you have a bit of an issue there.
What is the performance like? Does it feel like the handbrake is dragging?
Are any of the wheels very hot when you stop? Just wondering if there's a brake binding?

Hi, i have the same model and around 30mpg + is what i would expect. When its safe to do so, hands off steering and does it pull to one side or the other? 2nd the idea from enuff of checking for unusually hot wheels...you can also get a temperature gun to achieve a more reliable indication. Do they spin freely if off the ground? If you've worked on the brakes might be more than a coincidence , good luck

6 gallons of fuel ..that's around 240 kilowatts of heat if it was going into the brakes, so at say 44 miles per hour, that's 80 kilowatts going into the brakes over a 1 hour period.. mmh toasty..

Going slightly off topic, what sort of driving do those MPG figures represent? i.e. city, motorway, mixed etc? With regards to your issue I assume you haven't changed where or how you drive over this time? e.g. a mainly flat area to a hilly / mountainous area?
I've got a 2016 20i, I normally get around 27/28 bimbling around London (with an occasional bit of fun when I see an emptyish road).
My economy drops to 25/26 if I use sainsbury's supermarket fuel (Morrisons is around 24/25).
I get 27/28 with Esso standard 28+ if I use their premium 97 RON or Shell's good stuff.
Could it be the fuel?

Just driven 500 miles of motorway driving 80mph more or less no traffic jams. I have the 23sdrive manual version and with driver only and some light luggage. I averaged 32mpg (UK driving) in mixed urban driving I get 28-30mpg.
If this helps you judge your car?

I always use the cheapest petrol I can find. My 2.2 did over 40 on a run and my 3.0 does well over 30 on a good run and just under 30 around town.
So then, [ref]Leek78[/ref], no-one can shed any light on your potential issue, but you have at least discovered that everyone else's fuel consumption is much better than yours. 
I assume you have no smell of fuel, strange puddles under the car, starting problems (leaky injectors) etc?

If you had blocked fuel injectors the fuel burn would be less not more...there’s not much anecdotal evidence to suggest N20 suffer from injector coking..
Have you put an engine diagnostic / fault code reader on it ?
Iwould take a look at your fuel trims in live datra with diagnostics, if high then look for air leaks in the vaccum syatem across the engine from Maf to exhaust. Check all hoses rubber and plastic including intake from Maf to throttle body for holes or splits. Holes or splits will let unmetered air into the engine and when picked up by exhaust sensors will tell the car it thinks it is running lean so tell the injectors to add more fuel to richen the mixture. Usually this sets the EML and sets codes for fuel trims however it may have not reached the threshold it needs to set the codes. However frequent visits to the petrol station is an indication to this sort of fault. If you can't find any splits or holes, a smoke test would show them up or prove the system is airtight.
