I get about 33-37 mixed driving in my Cooper. It's the city driving that's killing you.

 

So i bought my mini used and never really went through the manual in regards to the computer. When i scroll through the various displays i have two different mpg readouts.

One which is 28.1mpg and two clicks of the button and i have another that reads 36mpg. What's the difference? Why is one so much higher?

 

One of the readouts is instantaneous MPG--what the car thinks you are getting at this moment. (It may be averaged over a half-second or so?)

The later one is an average MPG since you reset the readout. I forget how you reset it, the info is in your owner's manual. I haven't reset mine yet.


BTW, I drove in a quite "spirited" manner this morning on the way to work. Still got 33 MPG.

Thanks! I got to read how to reset and see what i'm getting with the new tune.

 

You can check it against the actual miles traveled and the gallons used. What I do is:

When I fill up, I write down the reading on the trip odometer, then zero it out.
I fill the car, I don't just put ten bucks or whatever in.
I divide the miles traveled by the amount that went in. That's miles/gallons, or MPG.

The above assumes that the trip odometer starts at zero and the tank starts full.

I have yet to reset the average MPG readout on my car. It started out reading fairly optimistic, but more recently the value is closer to the MPGs that I am calculating overall.

The instantaneous MPG readout has been fairly optimistic the whole time, at least in comparison to my ScanGauge.

 

I routinely get over 900kms per tank (560 + miles)
09 Justa,standard , light to medium weighted right foot.
LAst 2 months I run the A/C 90% of the time.
75% of my driving is at 80-90km/h (50-55mph)

works out to 40mpg US (50mpg imperial)

 

My mileage with the AC on is 28. I have a very heavy foot. Also, my drive involves mostly to stop and go traffic. Rarely do I get to run at a constant speed. On some of the MINI drives I have got as high as 35 mpg. These are "spirited" driving and has curves in the mountains.

 

Average over 8300 miles for me is just under 31, with a single tank high of 35.1 MPG.

 

Just clicked over today at exactly 33.0!

 

So i reset my mpg the other day and to date i am reading 29.1 with an overall of 38.4mpg

I'm happy with those numbers . I do an average of 14 miles / day on the highway.

 

My last tank of gas lasted 2 weeks and about 340 miles.. read out read 25 mpg that was a pretty consistent mix of city and highway driving with AC on. I wonder if my car needs service or something. Seems like everyone is getting better gas mileage then me!

 

It's probably just that the only people posting are getting above-average mileage.

I'm pretty sure I'm getting above-average.... :D

 

damn it I want to be one of those people! lol
a friend suggested one of those fuel system cleaners.. might try that on my next fill up

 

Which model and year? Our 08S got about 25mpg. It seems we don't drive economically. That was a 25% improvement over our 05S, and a bit better than our 12 JCW.

 

My 2012 MCS has averaged 33.2 mpg over 23 measured fills. Typically over 400 miles power tank, I did manage over 500 once...light foot, 38.9 on that tank.

 

I use a great app called GasCubby, which tracks everything for me.




This past weekend, in all-highway driving (some back-road "highways", the keys are practically no stop signs or traffic lights and almost-religious use of cruise control), I averaged 35.9 over ~400 miles.

I keep an eye on the "instant" MPG readout - not that I believe it's actually correct but so that I can see when I'm putting my right foot more deeply in the gas bucket.

 

I use a program called Fuelly. According to the stats in Fuelly my 2012 Coupe is averaging a running 28.7 mpg. The best was 31.4. This was tracked over 8,961 miles and 32 fill ups for a cost per mile of $0.14.

My wife's 2009 MCS automatic has a running average of 31.5 with a best of 37.8 over 48,403 miles tracked and 142 fill ups for a cost per mile of $0.113.

She is about 70% freeway driving at 65 mph and I am about 70% surface street driving at 40 mph.

 

By the way Fuelly is an online program that is free. I like free! LOL

 

OK, I did this with my last fill-up. I reset both the trip meter and the mileage readout. When the next fill-up came, it was 12.2 gallons. The readout said 36.2 and the calculated number was exactly 1 mpg lower at 35.2.
I'm happy with either one!
(I usually do about 30/70 highway/city)

 

I got 34mpg on a long trip in my 2011 MCS using cruise control.

 

I'm getting about 28mpg on my R55S. Heavy right foot. Having way too much fun driving it to even really care. I have changed the tach readout to show me what my "active" mpg is and i'm actually hovering in the 35-40 range when i'm just cruising on the freeway. I'm assuming once i stop having the urge to go fast, my MPG will improve. Question is... can i not go fast?

 

when i drive a little heavy foot i get about 26-27mpg. when i drive normal i get about 29-30mpg. its an 03 cooper s

 

I drive roughly 30% / 65% / 5% -> Stop and Go Traffic / Highway / Spirited. Generally my highway is between 65 - 75 mph. I calculate at every fill up and will generally run it down to 25 miles left til empty. I put in approx 13.2-13.6 gals per fill up. Also, this summer I have primarily used my AC instead of windows open. I have found that windows open seems to create more drag than AC drain on mpg...with that said i am seeing 32-33.5mpg on avg. Also...my major driving "adjustment" has been to shift at 3000 RPMs and try to avoid higher unless in "spirited-drop the hammer mode".

 

Ecstatic with 37.8 according to my OBC. My daily commute is 55mph backroads and teensy bit of city...
