Absolutely. Sometimes I drive around with the mpg computer on. On the highway, it ranges from ~30-60 mpg on cruise control. On the streets, if I drive conservatively, I can keep the mpgs above 30 most of the time by not pushing the accelerator too hard or revving too high. But when I drive like I normally do, I can watch the meter drop into the teens just before an upshift. That's why I'm averaging only 27 mpg.

 

Wow, you Cooper folks do well. Your numbers have me droolin'...

With my '03 Cooper S I average about 22 mpg (I have some mods, but some are supposed to improve efficiency--- my right foot has other plans). Even before the mods it was like 23 mpg on average. The best I've managed is 29 mpg on a long highway trip (nearly 100% driving at 60-65 mph in sixth gear).

Clearly, the 'S' is a big loser on efficiency compared to y'all's non-'S's, but I'm sure you already knew that

 

With 2000 miles on the mc I've been averaging 33 mpg

 

Right now I'm averaging 31.3 mpg on my '06 MC. My mileage has consistently improved from when I brought her home. I drive to work 23 miles/each way of which 10 miles is SUCKO stop and go averaging probably 10 mph. The next 10 miles is 80 mph interstate in heavy traffic which means cutting in and out and alternately stomping the living crap out of either the gas or the brakes (haha), and the other 3 miles is 50 mph, pretty much straight and level. I have 5,800 miles on my Cooper and have yet to take it on a trip really, so I'd say that the mileage I'm recording is pretty much "combined". I'm happy with 31.3 mpg on average. Considering my heavy-footed, agressive driving style, I think it's remarkable.

 

I'm at 29.63 including my trip back from SLC. I got 34.5 on that trip with ac on. My daily grind avg is 28.66, brutal S&G traffic with a passenger. I calculate manually as the OBC is +~2.5 off. I also haven't done a check with the last two tanks since I lost two sets of readings when I installed my iPod integration.

Lastly, I have a "heavy" MC with the premium pkg and Xenons which makes a negative difference. To counter I have the JCW SK and am sticking with 15" wheels.

 

We're getting about 35mpg on average...just two tanks run through the thing so far at 55k miles. The car is mostly driven on secondarys at 45mph and then on the highway, hence the decent mileage.

I just picked up my MC '06 "go-cart of death" (my bf named her) a week before Thanksgiving. I have about 1100 miles and went thru 4 full tanks since driving her off the dealer's lot. My average thus far is 28-30 mpg.

I know...she's still a baby. Though I'm hoping she'll improve with age.

 

With the 5 spd I typically get 32-33 in mixed driving according to the OBC. Sometime I'll have to check it the old fashioned way and see how that compares.

 

Best: 40ish mpg
Worst: 25ish mpg
Average: 34ish mpg

Better than I expected with my driving. Although I was being super extra careful when I got 40 mpg, I drove 506.1 miles on that tank.

 

I have an 06 MCC/cvt. The daily commute gives me 28-30mpg. Straight freeway 33-34mpg doing 75-80mph.

 

My 2006 MC gets 30 mpg in the city and roughly 37 mpg on the country backroads (with or without cruise control) .

 

I noticed about 32-34 MPG in the city. But Denver is a lot of highway travel, even in the city.

 

Now I've got over 8,000 miles on the Cooper and it is getting an average of 32.2 mpg overall (I haven't reset the mileage since new). Are y'all getting that same kind of result where your mileage is improving as you drive the car further? It's interesting, because my driving habits have been more agressive recently than when I first got the car.
IT'S JUST AN AWESOME LITTLE CAR!!!!!!

 

Okay, here's the next item for controversy.

I have been driving with my DSC off for about 3 weeks now (except, occasionally, on wet roads). My car's computer has shown a steady 27.3 mpg for months. Since switching off the DSC, the computer now shows the average as 27.6. This is the overall mpg since the car was new. I haven't computed an actual tankful yet since switching the DSC off.

My driving habits have not changed. In fact, with all the power now getting to the drive wheels, I have been driving the car harder to take advantage of it (hey, its fun!).

So, it is possible that the DSC, in its constant monitoring of what the wheels are doing, in cutting mpgs, if only slightly.

Now that winter has finnaly come and with 4400 miles on the mc I'm getting right around 30 mpg.I lost 3 mpg I think because of the cold temps.and the oxygenated fuel we have here in Maryland for winter time.

 

Yeah, I'm hoping that Obie's sudden drop of about that much mpg is due to the cold weather and not my new Megan exhaust.

I seen it before I installed the exhaust

 

I have experinced a drop off in mileage since I put the exhaust on but highway miles are just a little better.

I drive mostly highway,around 60 miles round trip to work 4 days a week running around 75 mph

 

I've got 8500 miles on my MC and fairly consistently average 33-35 MPG, combined driving. Back when I had the stock 15" "rocket" wheels, I'd average 35-36. And no, I don't burn regular gas - but I don't notice a difference between 91 and 93 octane. My '02 MCS got 22-25, but in fairness, it encouraged a much more agressive driving style!

 

i average 36 - when im on the hghway im usually getting an average of 40 but in the city it drops down to about 32-
i think its also a little worse in the cold weather than it was in the fall- anyone else notice this?

 

How do some of you with MCs get such high mileage?

I average about 32 mpg. I drive 80-90 miles a day 4 times a week. Majority is on the highway.

 

I now have 21K miles on my '06 cooper. Mymini exhaust, ITG filter, light, forged BBS 15 inch rims. Daily 90 mi. round trip commute, about half wide open 75mph, and half stop and go horrible traffic. Weekend short trips, etc. Tank in and tank out avg. about 32 mpg. When I do a lot of short trips and rev it up to about 5Krmp a lot, it'll go down to 28 or 29. Highest I've seen is about 35, but then I've never had a straight-out nothing but highway mileage run, or kept my commute down to say 60mph. For the fun factor, I think its great fuel economy

 

I've never had a non-S Cooper, but I've had two MCS (04 LY/B and 04 CR/W) and just bought a BRG MCSC. (BTW, I'm lurking here because I plan to buy a used non-S MC in the next couple/few weeks).

I have not had a chance to measure the MCSC MPG yet, but I kept flawless records on the two '04s. In our daily commutes, my wife and I would average 32-34 calculated MPG in mixed highway/city driving in a fairly aggressive manner. If I went and did some serious backroad bombing, I'd be down in the 27-28 mpg range. On long highway roadtrips we'd get 36. I never measured it at the track.

So, I'm surprised that so many non-S Cooper owners are getting such low MPG from their NA cars. Shocked, really. One word of advice: do not trust the OBC at all. There's only one way to measure true MPG:

1. Go to a pump.
2. Fill up your tank until the handle clicks off automatically.
3. Reset your trip odometer to zero.
4. Drive.
5. Go back to the SAME PUMP.
6. Fill up your tank until the handle clicks off automatically.
7. Record the number of gallons.
8. Divide the number of miles on the trip odometer by the number of gallons.
9. Record the data.
10 Repeat.

This is the only way you can find out what your true MPG is, and you have to be consistent. It will vary throughout the year with temperature and oxygenation in the fuel.

Calculating in this manner for over two years and 40K miles, I always got better MPG than what the OBC recorded or displayed. After my first few tanks of gas I just turned it off. It appeared to be off by 15-20 percent.

Note: Exxon 93 octane about 90 percent of the time. Occasional 91 oct.

BTW: fuel tank design and fuel dispenser nozzles are regulated by ANSI and SAE standards, so the pump should auto shut off at just about the same point at any pump at any station--but to be obsessive, try using the same pump at the same station everytime.

Also, I wish I still had my spreadsheet, but it went into the bit bucket when I sold my second MINI about 10 months ago. Now, let me tell you about the Honda Civic DX I bought that always got 44-46 MPG...and bored me to tears!
