Been running my VIS as a daily car for a while now and finding surprisingly good fuel economy. I knew it was good, after I once managed 38mpg on a long run.

This weekend, I drove to N Wales and back (320 miles) including "spirited" A road driving, fast dual carriageways, and gentle cruising. 36mpg overall. For a car which is only meant to do less than 30mpg, I'm quite impressed. I also think my Flea remap is the source of this improved economy, so hats off to him.

Bonus for such a good looking car as the Coupe.
Did you follow the A470?
Terrific driving roads through Wales if the traffic is light.

I'm off on a road trip through Wales in March.
The road from Rhayader to Llanidloes then over the top on the B road through Staylittle to Machynlleth, is beautiful.
Mach to Corris is tight, but the road from Minffordd to Cross foxes is superb as theres a wall by the road up the hill to amplify your engine noise. I just had to do it twice last year

Ps The Alfa average 21 mpg. Well, I was having alot of fun....

Yep Huw, A470 most of the way. I did take the Staylittle short cut though. Good B road blast.

Traffic was very light as the weather way atrocious, so makes a nice change.

Good man.

I never tire of the view you get when you drop down to the Wynfred Vaughan- Thomas memorial. It's breath taking.

I had sensation over load because the view appeared, the Alfa was on song and the guitar solo in The Wall came on. It was too much. My brain couldn't take in all of the positives.
I turned off the stereo, jumped out if the car and inhaled lung fulls of glorious air.
Man, that was a good day

The views are certainly stunning !

So we can assume we'll never see this under your username?

Heh. 4500 miles touring Norway a couple of years ago: 42mpg...

That’s impressive over such a long distance.

My best ever was 43mpg over 375 miles, but I was trying VERY hard. My last tank was 22.9, which is about normal for its current use. It managed 33 on a 1,000 mile round trip to LeMans and back, loaded with lots of camping kit

A lot of Norway is heavily speed controlled. But it did include the motorway/autobahn between Calais and Hirtshals in Denmark at more enthusiastic speeds.

That’s some impressive mpg! Mine averages 23 mpg but essentially lives in the city.

Actually, came very close to buying a 20VT a year or so ago.... the itch is there remaining to be scratched. I just find it hard to justify due to lack of space.

The point I'm making is that it achieved 36mpg without trying, so 40mpg should be achievable. Not bad for an old 2 litre with 169bhp.

My first company car was an 1999 (same year as my coupe) Astra 16v 1.6 Ecotec with 99bhp. I loved it to bits... and even that only did 36mpg on average.

Just means I have even more of an excuse to keep the coupe.

How do you work out the mpg?

Divide miles driven by gallons of fuel consumed.

But this only works if you brim the tank each time you fill it and note the mileage between fills.

If you buy your fuel by the litre, divide miles driven by litres of fuel consumed and multiply by 4.55.

(Doesn't everyone do this anyway? Fill the tank, check the odometer, do the sums in your head (roughly, at least), then zero the odometer... often the first indication of a problem is an unexpected change in fuel consumption.)

Yep. I only do it by the brim method.

Nerdishly, I quite look forward to seeing what I got !

My urbanish driving normally achieves around 28 mpg in the 20vt

I've never worked out the mpg of a car in 38 years of driving. I had a boyfriend who meticulously recorded his mileage every time he filled up and I thought he was a bit of a prat to be honest!

I do keep a rough eye on how far I go on a tank full, as Neil says, to be aware of if the car is running OK. Even with that, being able to notice a dragging caliper is not so easy until it gets quite bad! (OK it was my wife's car and I was less actively interested in that one).

I don't have the energy to do the calculation all the time

Then I moved to Wales.

I do that.

I also write down anything done to the car in the same book so I dont have to trawl through receipts to work it all out.

I don't write it down, unless it's on something like a European tour (and even then only on the petrol receipts until I get home and do the overall sums).

Mine is just the occasional check when I remember. I very rarely brim the tank (other than on the 17 litre capacity motorbike) as the resulting payment is too painful to consider.

The fuel receipt is the perfect notepad for me.
