Clubman Real Fuel Consumption
For those of you interested in some number crunching ... I filled Stewie up today for the first time from empty. (Computer stated, with much binging and bonging, that I had 6 miles remaining). I would not have let it get so low, afterall I had 19 miles remaining when I first reached the gas station WITHOUT my wallet!
On my previous top-off I reset all computers and topped off with Chevron Super. (It still had 1/2 tank of the original fuel in it)
Anyway, here are the numbers:

Anyway, here are the numbers:
- 50/50 highway/city driving, flat terrrain
- 33 aprox avg MPH
- A/C on 90% of the time
- 380.5 miles driven
- 13.605 gallons at fill up
- 30.6 MPG computer calculated
- 27.97 MPG hand calculated
- 2.63 difference between computer and calculator
- $4.15 a gallon total cost $56.58
- .15 cent cost per mile
- 693 total miles to date

Hey, 1.5 mpgs is not a biggie - in my not so humble opinion. For those who like to do the calculations with every fill up - go for it, and definitely post...but there are some of us who are just too lazy and will be fine with the OBC, given at least one non-OBC calculation.
There is a fellow who posts regularly on MINI2 who is very scientific in his calculations...perhaps you might enjoy reading his posts. His name is Dr. J and you can read about his ongoing experiments here: http://www.mini2.com/forum/mini-club...orld-mpgs.html

I am curious, though, and would like to know what you all *do* with this information? Other than for "record keeping", does it serve some sort of purpose that I'm just not getting?
Thanks!

Just curiosity I guess. I want to make sure that my MINI is performing as well or better than EPA estimates...

For me, it is just pure and simple OCD. I even made up a sheet that fits in the armrest of the car I drive now so I can keep up with mileages for a year at a time. I know, I can't help it.

Too much!
I started keeping a log when I got my first car, largely because that's what my brother did. That was back in the day that fuel taxes were deductible (for him). It also let you know if something might be amiss with the engine tune; much less likely now. But, it lets you know if certain fuel works better or worse, the impact of oxygenated fuel in the winter, running the AC in the summer. I also keep my maintenance record in the same log.
Okay, those are just justifications for being A-R.

Anyone have numers that compares mid range fuel with super? After this current tank of 93 I will try mid range.

Tracking gas mileage is also a great additional way to keeps tabs on your cars' health. Many fuel system / computer / ignition system problems will manifest themselves through lower mpg before getting bad enough to trigger a 'check engine'.
I put a vacuum gauge on my '78 Subaru way back when and drove with that for a while. It was amazing in a car with a carb' how much better one could do on mileage with a bit of training with a vacuum gauge.
