My Real World MPG
Here's my actual MPG from the first 2000 miles (MCS). The interesting thing is that the OBC rates me at 21.2 MPG. One would have to drive like "the little old lady from Pasadena" to get anywhere near what the window sticker states.

I have the regular Mini cooper, not an S, but I've had mine for almost 3 months (shortly after you, on September 18th, also from Long Beach Mini btw). And I have not had anything lower than 28 mpg. I took the car up to San Francisco this weekend and had two 31 and 32 mpg tanks for the trip up and back. I believe my OBC says somewhere between 28-30. My average mileage per tank is usually close to 375, even though the OBC usually tells me I can go about 425.
For what it's worth, I drive 5 days a week to work from Huntington Beach to Anaheim, and then my girlfriend lives in Long Beach and head there several days a week. Just out of curiosity, how many miles have you racked up so far?

It's a baby engine you've got to wait a while, stock I averaged 24 highway with some city, ALTA CAI less humidity even highway city mix I know get 28-30, 33 highway when around 70 (decrease over that speed) and I can pull in 35-36 if I'm under 60 and no traffic to deal with (rural non highway) I don't have an OBC so I use a similar method to your chart. BUt after a year I'm at 45.8k so everything runs a little more cohesive.
Thats a lot better than I'd get in your situation. I have proved the driving like I stole it (time on a road course) to mean 15mpg of course you're still in the break-in and shouldn't be much past 4500 RPM yet, 5l-6.5k is a golden good time, and worth the wait

My 07 MCS is now down to 34 mpg, but most of its 200 mile shave been in urban conditions so I'm not suprised.
I run mine on 97 octane though, may be this has something to do with it. Standard fuel is 95 RON in the UK, premium is 97/98, as far as I know we can't even buy 91 here. Assuming that 91 costs less you may find that compared with more expensive fuel you are getting further per buck.

I've been quite surprised at the drastic effect even "a bit" of urban driving does to the average on a tank. About 4 miles of my 18 mile commute is "traffic/ traffic light" type driving. It can very quickly take me from a 28/29 mpg to a 21/22 mpg. The traffic-y stuff is all accelerate, stop, sit driving.
Reports on Mixed-use "fun but not psycho" MPG averages for the MCS seem to cluster around 24mpg. Haven't heard too many convincing reports outside of that average.

In Europe you use the RON value, in the USA it is (RON+MON)/2
from wikipedia....
Research Octane Number (RON) is determined by running the fuel through a specific test engine with a variable compression ratio under controlled conditions
Motor Octane Number (MON) or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance.
Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally fuel specifications require both a minimum RON and a minimum MON.
In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-95 (regular) in Europe.

Over the last (ahem) 37K miles, my MCS has averaged 24.5mpg according to the OBC. The speedo is a little out compared to the GPS, it is 3-4% over.
Calculating from the fuel stubs and GPS distance travelled on a few long trips I put the error at less that 1/2 mpg. On my mix of road-trips, commutes, track days and california traffic I think that 24-25mpg is acceptable.
The absolute best I have seen is 31mpg, the worst is single-figures at Laguna Seca where I was consuming ~30% of a gallon of gas every lap........

actual miles
yes: I got my MCSca on Nov 8th '06 and I'm get really bad milage too. It's starting to worry me a bit because when I bought it I read stuff about how good MPG they get...I have a bit over 2000 on at I'm averaging about 18 mpg with mostly local driving and I have to fill up at around 240 miles on speedo. So the real question is how long is the break in period until I will see an increase of MPG ?? km

My
2006 MC gets 30 mpg...no matter where I drive it....city or hwy. Course on hwy its 70 plus mph. I've got about 12K miles on him now. Thought it would go up after broken in..but not yet. I don't use OBC...use Odom and gallons.

I've got 4,800 miles on my MCSa and I've averaged around 24mpg. Best was 26, worst was 22. The tank I'm working on now is definitely on track to set a new low - I've been using the manual mode hard in the last few days.

I don't drive like the little old lady from pasadena, and my 05 MCS gets right around 30mpg. I do a lot of highway driving. Two tanks ago I got horrible mileage, somewhere south of 25 mpg, so I put in a bottle of Redline SI-1 and now all is back to normal.

Hey Mini-Wingnut!
I did my own mpg calculations too and here's what I got for the first year of ownership:
24.723 mpg from mixed driving at a cost of $0.111/mile (last year's prices ranged from $2.099 to $3.739/gallon -- remember that crap in September?!).
Before the MINI arrived, I committed to always filling-up (to know how much of the previous tank is consumed), saving the receipts, and then plotting everything on a spreadsheet. I knew there'd be many uncontrolled variables (such as seasonal temps, times of day, lead-footing, etc.) but I just wanted to find out if different gas chains could have better gas, if my driving style could shame the EPA estimates, and whether my gas expenditures could feed all the children on that commercial...
Yes, everyone, I had a lot of free time; for every fill-up I lost a whopping 15 seconds of my life that I never got back! I don't think all those people who also lost 15 seconds waiting for me to pull away ever got their time back either... but the information gleaned from my pseudo-scientific study was worth the trouble. Especially knowing that I could fatten all of those children...
