Just done the first fill to click of pump tankful and was surprised that it worked out to 47mpg and 319 miles. That's driving around 12 miles with the low fuel light on.
Not that many motorway miles in that either and that was with Shell fuel, guessing it will be slightly less with supermarket fuel.
Happy though. :)

43.7 over the last 6000 miles measured tank to tank. Usually about 45-46 according to the dashboard. Mixed driving. On a long run (I've done Sheffield to Durham and back today) taking it steady I'll see 53 on the dash, which I reckon translates to about 51 in real life.

Highly recommend fuelly.com if you like that sort of thing!

After filling up on Friday I went for an 85 mile run, yesterday. It was a mixture of town, country and motorway miles, and my ScanGauge returned 54.4 mpg for the day. The dashboard display for the tank had a way too optimistic 62 mpg, but I know that over the tankful that will peg back and arrive at a fairly accurate figure.
I am disappointing by my mpg at present, and a check of the wheel centres on my return yesterday showed the driver front a little warmer than the others (the rest were stone cold). I have set remedial action in progress.

Pesky brakes!  ;)

120 mile trip round trip yesterday, with a few miles of town driving at the other end. Fibometer reset at the beginning and reporting 62mpg on arrival and 59.5mpg on return.

Currently averaging around 48mpg locally, but still haven't got round to doing that service yet... been occupied with rather more important matters.

Had my brakes checked, and they were not sticking in the slightest. Today I did a 100 mile trip, in warm sunny weather. Immediately on my return I pulled the wheel trims and all 4 wheels were stone cold.
Crisis over!

I think most people would be very happy with your mpg Jocko, especially on a 12 year old car. As a ball park you are over 12 miles per gallon ahead of me and I do try to drive carefully. It's my very short journeys that kills my mpg. I've noticed that there is a huge difference between 2 miles and, say, 4 miles, in mpg terms. Been looking at this using trip B.

I cannot complain, really. It certainly beats the 29.8 mpg that my Volvo S40 returned, during my ownership.

A very much improved figure this top up. Brim to brim, 412 miles and 56.4 mpg. (Fibometer said 57.2 so not too far off) What was pleasant was I only had one top up during April, instead of the usual two a month. More down to when April's fell (mid month) as it is more a case of 23 per year than two per month.

What a huge difference the warm weather makes to mpg. Today it is a dry and sunny 17 °C. I have done three short, cold start trips, all of them in town. According to my ScanGauge, for the 10.7 mile total, at an average speed of 15.8 mph, I have achieved 53.9 mpg. A week or so ago I was struggling to get near that on a long, gentle, run. Long may Summer (Spring?) continue!

Another warm, dry day and I had my usual, two up, weekend  trip to visit my mother-in-law, south of Edinburgh. It is about 60% motorway/dual carriageway, the rest a mix of town and country driving. The roads were busy, but apart from a couple of slow moving queues mostly the traffic was moving steadily. I gathered my ScanGauge E data for the day, and was pleased with the results.

Average mpg: 59.0 mpg
Max coolant temp: 84°C
Distance travelled: 83.0 miles
Maximum revs: 4055 rpm
Max speed: 61 mph
Average speed: 37 mph

Considering most of my driving was at around 55-60 mph it is surprising how much the average is pulled down.
Country and town driving gives the best scope for improving your fuel efficiency. On the motorway most people get what they get. I don't like motorway driving, for that very reason.
I am doing no coasting, all in gear driving, making best use of DFCO and "a raw egg under the accelerator". I am being particularly brisk in accelerating up through the gears (over 4000 rpm is unusual for me!).

Today, as well as my usual taking my wife to her work, and picking her up after, we also had a trip into Edinburgh city centre. Most of the centre of Edinburgh is 20 mph now (very strictly enforced), which is just as well, seeing how many ancient cobbles I had to traverse today. Here is my data from my ScanGauge E:

Average mpg: 64.4 mpg
Max coolant temp: 84°C
Distance travelled: 61.3 miles
Maximum revs: 4158 rpm
Max speed: 58 mph
Average speed: 29 mph


Very pleased with that. I am now back to adding a little coasting in, where appropriate, and the warm dry weather is making a huge difference, though Fife is plagued with the early morning haar during weather like this.



Some of the cobbles on today's route.

The average speed says it all. Driving that slowly, in city driving, using anticipation to avoid braking where possible and switching ignition off at known long lights, makes a huge difference.

Today my usual weekend trip was in warm still conditions, and according to My ScanGauge E, I averaged 67.1 mpg. And this was despite about 3 miles of 1st gear, stop start driving, due to a breakdown on the City Bypass. I am doing a bit of engine on coasting, when circumstances permit, and find that the car coasts great in this warm weather.
