After spending 3 days since I got my Sri 1.6t 200 seeing how fast I could go, I decided a better game was how high could I get my MPG to display.
On a run from Norwich to Great Yarmouth and back I managed to break the 50mpg mark, mainly on dual carriageway. That seems quite good to me but as I did not have a trip computer on my Astra GTC 1.4t I cannot make a comparison.
The best I've had was 70mpg on b roads during a 20 mile trip. I've now averaged 65mpg over the duration of over 1500 miles (mixed driving).
With my 1.6d (136). Also running with 16" Mich energy saver tyres. It's an auto too.
From Stoke to Liverpool on the M6 through the 50mph roadworks 75.9 mpg but it was a clear run with no traffic. It was creeping up till the return journey when I was queueing and it dropped. 1.6 (136) Elite ST manual.
If all onboard computers are as accurate as mine then they over read by about 15%
I recently did a couple of long journeys with some steady driving so brimmed the tank at each end of the trips. I got an actual 46mpg (51.5mpg on the trip computer) at around 70mph and in general use with a mixture of driving we get about 37mpg (42.5mpg on the trip computer).
As an add on to my last comment, the last tank has just done a rather disappointing real 30.5mpg after doing lots of short journeys although in fairly light traffic and it's not really been hooned around.
Running Costco 99 Super Unleaded just now and on average seeing about 44 mpg on the trip. Though that is a mixture of high speed runs (70 to 80mph motorway cruises and being stuck in traffic around Edinburgh). I really must at some point take mine out to do a eco run and see what I can get out of it. Then I'll put it in for a remap and see what I can get after that, once the knocking noise issue has been sorted.
Astra 1.6 turbo, 200 ks
In last aprox 5600 km, average is 7.3 l/100km
Or 38.7 mpg
This includes winter and summer time
And i always keep the left lane
My average speed driving is 47 km/h (29.2 mph) so that includes city driving as stated
I recently achieved my best ever calculated MPG of 44.6. The dash said 50.1 which goes to show that you should really ignore whatever it says.
I've also found that running Momentum 99 consistently gives me an extra 4 MPG, paying only 5p a litre more for it over regular unleaded seems like a no-brainer to me.
I don't even know how is this possible. I have the same car specs as you, the best I've done is 5.0l/100km and it isn't even accurate as the trip computer over reads. In reality is 10% higher.
In my 1.4T auto on a fairly short very economic drive (10 miles) I managed to achieve over 70mpg. The complete journey which was mostly motorway still came out at 60mpg. Fuel was roughly 50/50 Tesco Momentum and Sainsbury's Super. Speed was mostly around 50mph.
This engine can deliver amazing economy but only if you don't use the turbo!
From my 1.6 cdti 136 i get between 68 and 72mpg showing on the car on all tanks of fuel, thile car isused for a daily 92 mile commute with a combination of city, twisty a roads and motorway driving.
All tanks return between 700 and 800 miles each time to the point where the low fuel warning sharts flashing
On my 1.6cdti 136, I get 73 mpg pretty much consistently. That is long drives on the weekend of motorways and a and b roads. Then short town drives to work in the week. Get about 700 to 750 miles out of a tank.

This happens only once Last week i had a trip do the seaside and with 3 more passengers, language and speed about 120-140km/h on the highway i got about 5.8-6l/100km.
I used get 60mpg now I rarely get over 50mpg I use A roads to and from work and bit of city driving my driving hasn't even changed and the mpg had dropped loads
