#29 of 43 Milage around town by morgan5 Jun 13, 2008 (4:43 am)
Everyone talks about highway miles when discussing MPG, but I'm more interested in around town driving. My daily commute in my 2006 S is about 15 miles in stop and go traffic (no interstate or highway). Usually, I get about 22 to 23 MPG around town. Now that the temperature is getting hot I am running the AC most of the time and my MPG has dropped to 18-19. Is this normal?

Replying to: morgan5 (Jun 13, 2008 4:43 am) I've gotten 28 MPG under the worst of conditions - super-short stop and go trips with A/C on and somewhat fast acceleration. I'd say that's the bottom in the "entry-level" automatic transition model. It probably gets better as the car gets more broken in. That is using high octane gas. You don't want to use lower octane or it'll drive poorly at slow speeds, such as in parking lots, where you'll think there's something wrong with the car as it seems to search for the oomph to get going.

Replying to: minidrivermn (Jun 13, 2008 7:29 am) Minidrivermn, are you driving an "S" with a supercharger, or a regular Mini? Replies to this message: minidrivermn (Jun 13, 2008 10:36 am)

Replying to: morgan5 (Jun 13, 2008 4:43 am) 18-19 seems rather low as I got about 25 mpg in a 2004 MINI Cooper S with a similar style although shorter distance commute.   Are you using premium? Replies to this message: morgan5 (Jun 13, 2008 10:33 am)

Replying to: british_rover (Jun 13, 2008 10:17 am) Yes, I'm burning premium, but leven so, the MPG really seems to go down when I'm running the AC.

Replying to: morgan5 (Jun 13, 2008 10:11 am) Regular Mini. Not the "S" with the supercharger. As I posted earlier, the range is huge. The worst case scenario is in the 28 MPG range (bad weather, hot weather with A/C, starts and stops, very short trips, heavy on pedal) up to a 250 mile trip of 44.9 MPG without braking once and driving 50-60 MPG and no heavy accelerating. I think that's probably about the widest range anyone could produce with a Mini. Typical mixed driving will for sure be in the 30s, but high-30s is only likely with mostly highway driving, below 65 MPH, and good weather without A/C.
#35 of 43 What gas do I use? by nutomotr08 Jun 26, 2008 (10:41 pm)
I have seen some postings regarding this but I will ask again anyway. I have only had my MINI for about a week. As I was leaving the dealer told me I should use 91 octane. It is not always available, so when I filled up for the 1st time, I asked the gas station attendant if I could use 92 octane. (I figured the higher the better!?) and they said yes, it really wouldn't matter. Since then when idling and at low speeds my MINI is really sputtery. Is this because of the 92 octane? What should I really use, despite what the dealer told me? I have heard different stories. Thanks in advance for any input. Replies to this message: busiris (Jun 27, 2008 6:24 pm)

Your Mini will run acceptably well even on 87 Octane gas, although the mileage will not be quite as good. My wife's 2005 Mini runs on 87 octane beautifully. I would guess you are running a poor grade of gas currently.   I would suggest using a different, name brand gas (ie, Shell or Chevron) for a few tankfuls and see how it performs.
#37 of 43 Non-S 5000 mile trip 39.5 mpg by ilovebatz Jul 27, 2008 (1:24 pm)
We took a stock mini (non-S) from Evansville, IN to the Pacific Northwest and back, about 95% hiway driving, 5500 miles, and achieved 39.5 mpg. We used premium fuel at almost every fillup, a couple times we used plus. Best tank was 45.5 mpg, worst was 35.0 mpg. Didn't keep track of which gas had ethanol. Speedwise we averaged between 65-75 mph for most of the trip. We thought about taking the CRV but took Mini instead. We did take out the backseat so we could fit our camping gear. It actually worked out quite well.   I was impressed.   Regards,   Harry Faulkner
#38 of 43 Re: Mini S, High octane vs regular gas [morgan5] by ltq Oct 20, 2008 (6:53 am)
Replying to: morgan5 (May 13, 2008 6:41 am) I have a Clubman S, which shares the manual with the Hatch. It clearly states that premium is highly recommended, but also that 87 gas will NOT hurt the car nor void the warranty. Read the manual!! The knock sensor takes care of the car. As to whether the extra price of 91 gas offsets the poorer (as reported) mpg from using 87 gas, I don't know *yet* . I am getting 33mpg real (measured by gas fills of 91 octane) in mixed driving (31 mph average on a tank) on the turbo Clubman automatic (the worst mpg configuration). But I've got a couple of years of gas-pedal training from driving hybrid cars...... this makes a BIG difference.
