I've been using an Android app called FuelLog since just before Christmas, and can confirm that the 129.9/l of unleaded I paid yesterday is the cheapest fuel has been since I started using the app. There were a couple of occasions when I paid 129.9 but those were with Tesco 5p off per litre vouchers. The most I paid in this time was 140.9/l. Over that 6 months I've only done 4567 miles at an average of 30.95mpg therefore a fuel cost of 20p/mile. Unfortunately, due to a recent insurance renewal and the big brake job the other week, the accumulated costs (fuel and other costs) are currently 43p/mile (it was running at about 23p/mile until a couple of weeks ago

).
So that means, in the 6 months since I've been tracking it, it's cost me an average of...
£10.28 a day
£71.99 a week
£312.85 a month
£3753.74 a year,
or to put it another way, i've done an an average of just 2.35 miles per £
Of course, calculating all this over such a relatively short time period and off the back of a big bill is going to skew the results, I've had this car 10 years and the total cost of repairs (excluding service items and consumables) is way less than 2 grand, so I reckon the realistic accumulated costs are more like 25p/mile, which is actually very cheap motoring for such a big, comfortable, versatile mile muncher. In fact, even if you figure in depreciation (around 13.6p/mile on my car) then it's still less than 40p/mile in total, which is incredible. I bet my next car won't be anywhere near that cheap to run!!
