Lots of people have reported average gas milage with some pretty big differences among them. For example, the MCS range seems to vary from as low as 15-16 mpg to as high as 25-26 mpg. What's never provided though, is the average speeds that go along with these results.

Over my last 357 miles I averaged 19.9 mpg at an average speed of 21.3 mph. After filling my tank this afternoon I averaged 22.4 mpg at an average speed of 22.8 mph over a distance of 14 miles.

It would be neat of some us could compile stats on average gas mileage ALONG WITH the associated figures for average speed. This might help alot with making more accurate comparisons, especially for those of us whose gas mileage doesn't
appear to be so hot.

This is pretty easy to do since the info is right in front of your face whenever you're
behind the wheel!

 

Right off the top of my head:

'04 MCS, 4,800 miles:

City: 24-26 MPG in mostly stop and go traffic. A/C running most of the time.
Highway: 34-37MPG

Gas used: Exxon/Mobile 93 octane

Average speed in city driving for both 24MPH.


'02 Cooper CVT, 19,800 miles:

City: 28-30MPG also in stop-n-go traffic with A/C running 100% of the time
Highway: 37-40MPG in "D" mode take off 2-3MPG in SD (Sport Mode) and Steptronic modes.
Gas used: Exxon/Mobile 93 octane

Cars are driven in Miami, FL. Altitude 11ft above sea level.

2003 MCS @ 12000 miles:

Around 24mpg. I cruise between 70-80. In 4th, and am more spirited than the average commuter in the San Francisco Bay area. Gas is usually from 76 @ 91 octane. Mostly city driving, but use I-80 everyday Using hand calculations and not the built in mpg estimator.

I also have an ALTA intake,pulley, and upgraded Powerchip ECU which may help or hinder fuel economy.

 

2002 MC seems to always get 27 MPG with an average speed of 34mph. Its odd but every time we check the average speed it at 34mph +/- a couple must be our driving habbits.

We have checked highway mileage and have gotten as high as 35 in constant freeway driving with the cruise on but typically its about 32. It has gone as low as 20 in winter driving slogging it through the snow.

 

03 mc 11,889 miles 91 Octane various sources. 30.1 mpg 28 mph avarage.

 

I'm getting about 26 mpg from my 04 MCS with an average speed of about 25 mph. That's mostly commuting with a fair amount of traffic and stop lights.

 

03 MCS, 15k Miles 27.0 MPG, 33.3 MPH (speed and mpg figures for last 1k miles).

'02 MCS, 2,500 miles on her, 24.4mpg on average, tracking all fillups since purchased. Mostly city driving, some trips on the interstate in the mix as well. This is also with the zip-tie yo-yo fix, which I was worried would impact fuel economy. No way to guess average speed.

 

GBMINI has given me MPGs above 31 on a good highway run with speeds held around 70. In the winter, with short runs with the engine not warming up quickly, my MPG has been below 25.
The worst MPG was when it was at Tweeter for a (botched) stereo install, with the engine running and doing 0mpg for a very long time - the average was about 15!

The recent John Cooper Works upgrade does not seem to have affected MPG - latest tank a little higher but proably due to the warming weather with high temps up to nearly freezing now!

03 (May Build) MINI Cooper CVT: 24.2 Miles Per Gallon/Avg speed 31 MPH. This is in regular "D" Mode. I rarely use SD. I think my "mediocre" gas mileage has a lot to do with the short distances I drive the car each day...about 4 miles to and from work, and then another mile or so to and from lunch...so yea, 4 very short drives per day really lowers the gas mileage. When I drive it on the highway, crusing around 70 MPH, it averages about 32 MPG.

9,010 miles on the car, going in for its first dealer-serviced 10K filter/oil change on Monday.

BTW, I sent an 8 oz. oil sample to Blackstone Labs this week for analysis. It's a sample siphoned directly from the oil pan, at operating temperature (meaning I drove the car for 10 miles or so before taking the sample)...the oil had 8,932 miles on the oil when I took the sample. I eagerly await their analysis...I'll post the results when they arrive.

Rock On,

My OBC says my average speed is 29mph and my average gas mileage is 24.
But I only have 2.5k miles

 

MC 5-speed with 15" summer radials: 33-34mpg with average speed in the mid-50's. Yes, I said mid-50's. 80% highway commute, usually cruising at 75-85mph.

 

2003 MC, 5-speed with runflats, 7500 miles. Averages 28.5 mpg in commuter/arterial driving, plenty of traffic lights. But at a steady 70mph on the highway I squeeze out about 34. Mostly 91 octane fuel.

Giving an indication of driving style in terms of typical RPMs you keep the engine at, or shift at should help too. I've averaged 26 mpg on my 04 MCS with mixed city highway ( mostly city). Highways speeds are about 70 mph and I keep to within 5 mph of city speed limits :smile: . While in the city I shift just over 3K rpm and keep it at or below ~3K rpm while cruising. I do have a few spirited burst up to near red line. :smile: :smile:

 

Usually 28.5-31mpg. average speed?? below 50mph for commuting.
you mean average RPM? then im at about 2100-2300rpm's cruising.
I dont rev past 3500rpm during the commute.

on the weekends, i take it up to redline and drive pretty spiritedly..
but still manage about aveage 28+ mpg

 

Brand new CVT MC, so I'm baby-ing it.

This AM, I had my first fill-up at exactly 300 miles driven and put in 10.1 gallons

 

Please search for past threads on this subject which has been discussed many times.

Many of you are using your trip computer to give you these numbers esp ave speed.
All of the data from the trip computer must be considered a rough estimate and not always very accurate.
If you want real mpg then you have to manually calculate it which has been done already.

My 03 MCS used to get about 28 or 29 mpg when it was stock with mixed driving mostly highway.
Now fully modded except for ECU I get about 26-27 mpg with similar driving. On a track day I get about 21.

MC have reported more like 30-34 mpg with general use.
Some MINIs report less than 20 mpg with mixed driving- not sure why- no known reason is found.

 

FYI: My 2003 (march build) MCS's computer always reads 10% optimistic...I calculated longhand for a while in a log book - it was always 9%-10% off. With that said, here it goes:

19.5 MPG
17.7 MPH ave speed (slow!!! to much traffic!)
(aggressive full-throttle spurts when trafic allows!)

Here is another important factor - Oxeganated fuel!! It stinks! Same drive, same car in the summer (with out the winter-mandated oxegenated fuel) is over 21 MPG. So please post if you have the oxegenated junk or not....

*RANT ALERT* Oxegenated fuel is suppoesd to lower cold-start emissions and help with polution in densley populated areas.... Too bad most cars built after the mid '80s have O2 sensors and ECUs that compensate for the cold starts. So, the majority of cars on the road don't really need it. Here is the annoying part...it is supposed to HELP pollution...but you get LOWER MPG with it and most cars on the road don't need it to compensate for cold-start emissions. Another example of our messed-up EPA.

 

I average about 21mpg in city driving. The roads around here are very twisty and although I am no speed demon, I do have fun on the curves. . . .

On the highway, at a reasonable 70mph, I get 28+mpg

 

'04MCS 1700miles: I average 26MPH overall and get 23.1MPG avg. Mostly city driving with some freeway lunacy thrown in. On longer runs (cruising around 80 with a bit of hill and dale thrown in at either end) I get between 34 and 35.

I have to say that my city driving MPG is likely due to my bad habit of constantly seeing how quickly I can get away from traffic lights (redline in 1st and second).....

 

'03 MC CVT: 25-26 MPG at average speed 27-28 MPH, both directly from the OBC (unsure of accuracy...I have not done a manual calculation yet).

 

'04 MCS, mostly city driving with occasional 15-20 mile highway jaunts. According to the OBC, I've never dipped below 23.0mpg and my car sees 5,000rpm at least 5 times daily (after she's all warmed up of course :smile: ).

 

I'm finding the feedback here very informative. So far, I have calculated the info
for the nine people who gave fairly SPECIFIC numbers for gas mileage and speed.
The average was 24.5 mpg at a speed of 26.9 mph. This is a ratio of 1 mpg to 1.10 mph.

Using these numbers, my gas mileage of 19.9 mph at a speed of 21.3 mph is almost as good someone who gets 24.5 mpg at a speed of 26.9 mph. The ratio for my personal stats is slightly worse.....(1.07).....and this makes sense because I'm probably heavier on the throttle than the typical driver and most likely tend to shift at higher rpm's (a 15% pulley tends to encourage this kind of driving).

My conclusion, based on this very limited sample, is that my gas mileage is just about as good as others who are averaging 4-5 mpg higher......especially because
I have an MCS for which the numbers clearly are lower than the MC.

This helps to explain my 'mysteriously' low numbers and now I feel alot better about my Mini's gas mileage performance! Maybe you will to!

 

My OBC reading is 27 mpg City driving with an average speed of 30mph.

 

I've long suspected that the OBC was giving me suspiciously high mpg averages. This past weekend with 2,500 miles on the car now, I took a 250-mile trip and kept accurate records of two tankfulls of gas. Highway use mostly, averaging 65-75 mph most of the time.

The OBC told me I averaged 30 and 30.5 mpg for the two tankfulls. My hand calculations showed I actually was getting only 26 and 26.5.

Because the car is British, could it be possible the OBC is calculating mileage using the larger Imperial Gallons rather than U.S-sized gallons to calculate those favorable figures ??? I wonder. If so, that would certainly explain the greater number of miles per gallon that the computer is telling me I'm getting.
