Someone reverse-engineered a flux capacitor!

 

Put in 10 gals (filled it) and ran 245.5 miles.....mixed driving city and hiway....at speeds of 70-85 mostly.

OK...question about this OBC....not all minis have it, right?

 

10 gals fills your MINI? Wow!

I can get 3 in it with me driving... max (my wife prefers me to not have any in it - excluding her, of course)

To answer your question, the OBC is an option - I don't believe it's on all MINIs.

 

When I filled up this morning, the light had just came on, I put in 40 litres, at 614 kms(382 milles, 10.56 US gallons) So looks like I got 36mpg.

350 miles highway, 32 city.

Glad thats over

Going to go drifting around the gravel backroads this weekend, won't get anywhere near that

 

The honor system rocks! In my '06 MC (technically still on order, but I've projected mpg with at least as much credibility as the increased hp figures of most aftermarket posters), utilizing my granny technique, 3 lb per corner forged alloys and hot pink spark plug wires, I've gotten such incredible fuel economy that I literally have to stop every few miles and drain the excess gas accumulating in my mini's tank.

 

Ok, so I've gone about 375 miles so far, light just came on. I'm guessing, at the worst case scenario, I'll be putting 13.48 Gallons in, which puts me at 27.7 which I hope doesn't happen.

I'm filling up tomorrow morning. Wish me luck! I want to brag to my friend that my MINI got better mileage than his wife's corolla (~31.6).

 

At 1/4 tank left, I was at just under 350 miles on the trip and about 100 miles to go according to the OBC. I averaged 32.2 MPG in my '05 MCS. I shifted at 3k at every shift (except for 5) and went only 58-60 MPH on the highway. About 75-80% of the miles were highway driving.

I don't have the exact figures right now, but my OBC is usually off about 1%.

I hope to never do that again; it wasn't much fun.

 

31 mpg +/- a little. Averaging 85-90 mph. Got new tires recently, I think the pulley/CAI combo works really well for fuel consumption--no ecu chip. Actually had milage lag because the dealer did not inflate the tires all the way according to the side walls. We fixed that and pulled out 3 extra mpg. All autobahn driving though, so no stop and go. Can't wait to see what we get in the states...

Last week I got to 655km with 30km left on the range (all non-stop highway driving) including a bit of 'spirited' accelerating....which was about how far I had left to go....but I don't trust that thing, so I chickened out and filled up....

 

OK, the figures are in...

Gallons: 12.178

Trip: 379.1
Trip mpg: 31.13

Miles before: 582
Miles after: 962
Miles mpg: 31.204

Of course, this is essentially 31 +/- a little bit. Happy, since I got 30.6 the last time.

I'm also doing a calibration curve for my gas gauge - I am trying to fill up at 1/16 positions (ie, 1/16, 1/8, 3/16, 1/4, etc...) and plotting it. I have no clue how to determine the actual error, so I'm going to have to guess.

 

My average since I had my CooperS has ben just under 23 miles to the gallon. I actually drive a good amount on the highway and while I certainly do not drive like my grandma, I am also not torquing it all the time. I am a bit disappointed with those numbers. Even prior to the roofrack the numbers weren't much better. :-(
So I guess I finish dead last here?

'05 MCS 6-speed manual
Mileage: 4,200
Gas used: Citgo Premium 93 Octane
A/C all the time: About 90% usage

Thanks to kaelaria's money saving suggestions, I managed to get a solid 26MPG in strict city driving this past week. The last fill up lasted 325 miles

I did nothing different but to shift at or below 3K RPM, use the higher gears much more often, keep my tire pressures on check and avoid sudden "jack rabbit" starts and hard braking.

 

Ok, with my MCS '05, I've been floating anywhere between 25.8 to 26.1 mpg. Just refilled the tank to 12.499 gal and traveled 318 mi. which comes out to 26.3 mpg. Looks like the OBC reading is a fairly accurate reading of my driving.

I would have to say that the # of miles left reading on the OBC is way to sensitive to use as a factor for mpg - as soon as I get down to half or less than half a tank, the # number of miles left look as though they are decreasing at an inversely exponential (vs. linear) rate while I continue to drive.

 

I didn't keep up with the gallons or miles, but according to the OBC I got 29.7 MPG. That's in my automatic S, no A/C (except for the 10 minutes I was at Sonic), and a round trip each day that is about 50 miles highway, 10 miles city. Previously the OBC was saying a 22.5 to 23.5 average, so I'm happy

 

MC @ 100% city

30.51 MPG
346 km, 26.67L of 91 octane

Gunning it every chance I get (lots of 6000rpm shifts, 20% traffic jam), about 40% AC usage.

I honestly have not shifted below 3k rpm since the first day I got the car Even during break in period I was shifting right at 4500 everytime

 

I figure that if I stayed at 60mph, did not pass, on a long trip I'd get over 40mpg easy.

That would be below the posted 100kph(63mph)

Boring though

 

Well, here are my official results from a not-so-scientific test environment:

I greatly moderated my "spirited" driving style by driving with the AC off (when bearable) and shifting at 3000 rpm.

City: 28.5 average over 70 miles (I have a short commute to work)

I didn't do enough highway driving to get results from that driving style, but I did accumulate some highway miles yesterday going to a pulley party... I drove "normal for Dustin" and got 33mpg - I was much more concerned with getting there in a timely fashion.

My conclusions (common sense anyway)
1) AC is a factor - the actual drag is unknown but it is not entirely trivial
2) RPMs are a factor - low rev shifting will conserve fuel at the expense of fun (and potential carbon build-up & ECU adaption I would expect)

My observation/supposition:
With these cars, driving very conservatively seems to be like a diet - at first you achieve results, but eventually your matabolism adapts to the new caloric intake and the weight loss is less significant. The ecu seemed to adapt a bit in the short time I was driving like a granny, and when I tried to drive it like "good old Dustin" it was actually sluggish for a while.

My summary:
I enjoy driving my MINI in a spirited fashion way too much to fret over a few mpg. If I wanted a prius I should have bought one of them. The car will certainly allow you do drive conservatively and sip fuel a little better, but it's designed to squirt around town in zippy fashion, not be passed by kids in their hondas with coffee-can exhausts.

Thanks to everyone who participated - it was fun to focus on conserving fuel, but the amount saved isn't (personally) worth the reduction of the "fun factor" - perhaps this mentality is why we're paying $3+/ gallon of fuel to begin with... mea culpa.

Keep posting your findings - I'm sure I'm not even close to seeing how mild-mannered a MINI can be.

 

I went to see my son-in-law graduate from Ranger school on Fri. Here are my gas numbers. The MPG are from the computer and I've found they are about 2 - 2.5 higher than what is actual.

Leaving Orlando to Tifton first fill-up (I started with about 90 miles on tank).
29.7 mpg
321.8 miles on tank
56.7 average spped (I don't know if speed is off like the gas is or not) I use a GPS (on dashboard) and it's more acurate I believe and it's about 1 mile under car system, but I didn't figure it in anything, just an observation)

Tifton to Ft. Benning
134.4 miles from Tifton
57.7 mph average
33.6 mpg

Columbus, GA to small town 10 miles from Tifton (gas was only 2.87 for premium) (same tank from Tifton)
124.4 miles
59.1 mph average

Small town in GA to Orlando
31.7 mpg
66.4 mph average
269.8 miles from GA to home

It looks like in playing with the system that A/C makes about a 3 mpg difference when off/on. I ran with the A/C off when I left yesterday early AM, but had to turn it on when I got back to FL. Sun was hot.

Like I said, not very scientific, but it did give me something to play with since I was by myself on this trip.

Now have 14664 miles and it's 8 months old. Another trip to Cinci in Oct. (maybe 2500 more miles).

 

I hope you brought him some food

 

Well we didn't bring him any but we did eat out a lot. He lost 35 pounds during the 61 days of training. His friend that came with him also lost a lot of weight. Not sure where he lost it from, Josh is a stick already.
I can't wait until Fri. they are coming down for a delayed honeymoon at Disney World so it will be good to see them (again).

 

Well I tried the 3k shift thing and almost fell asleep on my way to work last night So I went back to my old habits and shifted around 5k and had a few 6k+ shifts getting around folks sleeping in the left lane!

My commute is 80 miles one way, with 6 miles of 2-lane Mountain roads in the beginning and 2 miles of rural "town" roads at the end, the rest is all interstate or 4 lane divided highway.

Results: 346.1 miles on 11.885 gallons (filled at indicator coming on) equals 29.1 mpg (OBC read 30.6) average speed 59.8

 

My test covered a typical work week tankful. Three days of driving, 101.3 miles per day avg., 15% city/rural, 85% hwy, AC on coming home in the PM while on the hwy. My usual driving style is "spirited" with shifts between 4-5K rpm. Highway speeds were 75-85 mph. Results: 10.55 gallons for 304 miles averaging 28.8 mpg. I have observed 26 to 30 mpg over the 23K+ miles I have driven since last December.

 

287.5 miles and 11.6 gals of 93 Octane.....

24.78 mpg.....90% hiway 75-80 mph, AC on always.....

I am sure I can do better, but I have this need to put my foot in it, and since it is about 50% better than I was doing with the Hemi, I am pretty dang pleased.

 

My homework assignment:

1 week
255.8 miles
7.695 gal of 93 octane
OBC says 30.5 mph average
OBC says 35.6 mpg
255.8 / 7.695 = 33.24 computed mpg

I drove like a grandmother. It was terrible.

Can I go outside and play now?

 

Bullfrog, you've done a good job. Now go outside and play nice with the other MINIs.
