Curious what MPG most are getting. I've calculated the last two tanks and I'm getting about 18 MPG I thought it would be a little higher.

 

21 on mine, mostly shorter trips under 5 miles.

 

Should be around 27 - 29 mpg for a Cooper 'S' in US gallons, 32-34 for a Cooper.
You should really calculate over several tank-fulls - individual tanks will be misleading.
My 2002 R53 'S' has averaged 27.06 over the last 5 years - a high of 31 & a low of 23.

Low tire pressure, excessive toe-in, and clogged air filter are all low hanging fruit for possible causes.

 

My 2005 R53 (manual) has delivered 20.6 mpg for the last 10 years. I drive the beast twice per week to my job...5 miles each way. Mileage is now 72K. And I always buy my 93 octane fuel from the same service station (only one gas station on the island). Oh, I never turn off the air conditioning..as I live on Palm Beach. And I drive very gently....overkill gently. Seldom above 35 miles per hour. And smoothly. When the mpg dips below 20...I will address the issue.

ps I calculate mpg both by the computer...and in my pea sized brain. My 2016 Countryman S achieves better gas milage. Same driving habits.


yup,

Monkeyjuice

 

2004 R53: When I commuted to work and drove mostly freeway miles I got 25-27 mpg (sometimes higher before I got a 15% pulley). These days I take mostly shorter trips and get 22-24 mpg.

 

Im getting 16-18MPG.

Probably the way I drive and my mods though!

 

I have a stock 06 MCS JCW and regularly get 29.5mpg and 30.5 with all freeway driving (if i am not driving like a wild man!). I live rural, so not much stop and go.
I had an 05 MCS and it got a little better at around 30mpg most of the time. I keep it tuned up, proper tire pressure and use cruise control, when on the freeway.
I also had an 06 Justa rally model and it was getting 44mpg and average around 40 mpg.
Living in the country helps a lot!

 

I pushed it to 30 MPG once on a cross country trip, but generally get from 26 to 28, which isn't too bad. The premium gas is killer though

 

 

The computer says I've been averaging 26.1 on my 05 MCS. I have a CAI and pulley. I've also been driving conservatively.

 

Like HaltCatchFire, I get around 21 MPG around town with a properly maintained 2003 Cooper S. This is calculated MPG, not computer MPG which is 10%-15% optimistic. Road trips average around 25-28 MPG. Now at 157K miles, its dropped around 3 MPG from new.

 

Mine is miserable... My Suburban gets better gas mileage and I flog it...

 

It is hard to believe you are getting that poor of gas mileage, unless you have huge injectors installed and the tune is off badly.

 

2016 MCS JCW exhaust/tune. 34.3 per mileage indicator. 80% highway and 40 lbs all around.

 

I can not believe the MPG you guys are getting in these. I just got one from Canada....and have not been calculating the mpg. Next fill up I will figure it out and convert it to mpg. I sure hope it is better than that.... It might not be..because my wife and son have driven it mostly

 

Ive been burning through 93 octane at between 29-30 (US) mpg since getting my stock 2005 justa ragtop in July. Thats a mix of stop&go , highway driving and a suburban commute with one or two longer funday drives, but pretty much driving it like I stole it all the time (as one should in a mini).

 

 

Justa cooper, not an "S"

 

Trust me, I'm with you. I usually don't drive more than the 7 mile commute to work which is in typical Houston stop and go traffic. I usually try to drive smoothly and don't race up and brake hard... For example, if I watch the instant MPG meter, gently coming from a stop to 40 mph without going over 2,500 RPM it says 12 - 20 mpg. As soon as I hit 40, and put it in 5th or 6th, it will jump up to 40 MPG or so...If I actually accelerate like most traffic does, the meter is more in the 8-18 mpg range... It drinks fuel to accelerate. My car is not heavily modded, just a DDM Works CAI, 15% pulley, JCW plugs, wires, and Milltek resonated exhaust. No tune or injectors...

I don't doubt if I drove out to the suburbs or went on a road trip I could get 30 MPG though. But city driving, my computer says 18.5 mpg is my average.

I have to say that 18.5 is a bit sad!
If you look at http://www.fuelly.com/car/mini you'll see that the average for a JCW & similar is in the 24-27mpg in US gallons range.

Just for reference & having seen several different dashboard computers on different makes & models, I'd say they are all optimistic by 1 or 2 mpg.
I'd largely ignore the 'instant' reading other than for fun - I've seen 99mpg coasting downhill & 2mpg leaving a toll-booth!
It's important not to reset the reading too often - most calculate the average over several tanks or miles, so the longer you leave it between resets the more accurate it will be.

City driving is tough on economy - maybe a tune-up would be worthwhile?

 

I leased a 2004 GTO a few years back. LS1 350 HP V8- at about 3800lbs. I only fed it regular fuel, I beat the poopoo out of it. As a reference, I went through 4 sets of rear tires in 17K miles. I never got under 16mpg. On the highway, fully loaded trunk, back seat, and father at my side....30mpg (Vacation trip) Your Mpg is ridiculous..

 

2006 R53 145,000 miles. I get 26.7MPG

 

I agree, but I like to think mine is in top shape...new air filter, new plugs, new wires, top tier premium fuel... what else could it be? The car runs great overall and has been reliable (probably until just now since I typed it...) haha
