Not been on here for a while. The car has been running fine so nothing to be replaced.

I'm a bit older than most of you and being retired I am always trying to get my money to go as far as possible.

This last weekend we have done a round trip from Wakefield to Didcot and back. 360 miles. I was able to fill the car up on departure and then fill it up immediately on our return.

The in car computer told me it returned 49.2mpg.

My calculations gave 45.02mpg. 36.31 litres divided by 4.54 = 7.99559 gals. (Ok I know I'm a bit of an anorak)

Can anybody confirm whether these figures are good or not so good please?

Fabia 1.2 Classic HTP.

IIrc there is a sliding scale of efficiency dependant upon speeds, gears and how you get to speeds

I aim for 56 mph for optimum fuel efficiency on a long run, but my pal goes 62 mph

Also the conditions play a big factor, a prevailing wind could impact by 4-5mpg

Hi Binzie, yeah appreciate that mate.

I just thought that seemed quite good and wondered what other people thought.

It was all done on motorways and trunk roads at 65-70mph average speeds.

One passenger down and 2 back. No harsh acceleration or braking.

yeah sounds good to me

Sounds pretty good to me too. Is your 1.2 the 6-valve, or 12-valve version? (Engine code AWY or AZQ)

What year and how many miles has it done?

My g/f bought one of the 12v AZQ-engined ones in February and I've been keeping records for every fill-up. First 8 or 9 fill-ups averaged very close to 40mpg. Having replaced the EGR valve recently after finding a problem with it, this has gone up to 42mpg for the last few tanksfull.

This is with mixed driving, not much motorway, variable length journeys mostly short-medium length.

From what I can see, keeping the cruising speed at whatever corresponds to 3000rpm in top gear should be optimal.

Speed seems to be largely irrelevant to the economy on my 1.4 16v - much more important is consistency. When I'm on a motorway doing 70 (and holding it almost dead on) I will just just as good economy as when I'm doing 50, but what hits it is the slowing down and stopping.

I've seen an indicated 50.7 on the dash on a trip from Oxford to Birmingham before, although obviously the dash always overestimates.

Thanks for that lads......Wino, ours is the 12v version. (First time I realised it isn't the basic version.) From memory, it's actually my wifes car, it normally runs around the 42mpg mark in normal usage, but she is a bit heavier footed than me.

I think 3000RPM corresponds to about 62/63 mph on the speedo.

Andrewkeith5....lots of forward planning and no braking if possible is always how I try and drive.

I once annoyed the crap out of everybody else on the road on a back roads trip to Scarborough and back, but registered 61+ mpg on the in-car computer. Tried not to stop at all on the journey.

Thanks all for the interest.

Interestingly, I always calculate that my trip computer in the diesel under-reads slightly, by about 2mpg.

I manage roughly 55mpg a tank in the 1.9tdi PD...

mines a 1.9 sdi fabia 02 I am getting 65mpg round town and 70+ on the motorway 385 miles mixed driving on £40 of fuel

I once had a 1.2 12v Fabia as a courtesy car. I found it very nippy around town (with a light gear change) and loved the sound it made when you revved it. If I can remember correctly I got 40 mpg from a tankful. I normally get 45-50 mpg from my vRS, but it is a diesel.

I'm pleased someone else in the country has a sensible driving style! Once or twice I've managed to never use the brakes for an entire journey, even stopping doesn't need it sometimes.

I'm starting to get the impression that perhaps the trip computer makes assumptions irrelevant of the fuel type, hence it making sense that petrol cars' actual MPG is lower than indicated and diesel is higher?

Possibly, we'd have to ask more people to report their findings!

I've just started using fuelly to check my mpg - its worth a look!

With the diesels they are super fuel efficient between 40-60, if you do a good run at those speeds you easily get high 60s, but when you start doing 70-80 it drops off quite quickly to the mid 50s! So basically I can be very efficient, if I have the time....

What is 'fuelly'?

andrewkeith...never thought of that, but seems right about the car computer.

Can a mod delete this as a double post

That's my findings on a 1.4TDI. And round town it's about 55 MPG. On motorways, I average a bit less,as I have a heavy foot.
