I think you need all the warning you can get,

My car has a fuel gauge, it gives plenty of warning that the fuel level is getting low.

12 miles remaining (according to car).
I wouldn't trust the computer's "miles remaining" at all. It was discussed here:

12 miles seems to be much less than the possible error in the calculation.

600 miles on the clock since new so not run-in yet. Computer says average mpg of 51. Mix of town and motorway driving. Very pleased as my previous car (a 2005 Corolla) did 37mpg average.

3778 miles, 49.7mpg (10.94/ltre).

This is 4.53mpg better than Mk2 traded in

The 49 ish mpg is what I get. Ish is accurate enough for me.

Now that summer is over mine has dropped a little. My typical drive is a commute between Brackley and Banbury. 10 miles of country A-road at 50mph. 2 miles of town driving which is a bit stop start in the evening. I'm managing 52mpg pump to pump at the moment. The car is claiming 55mpg :-/

I'm hopeful that I might keep things above 50mpg over winter but it's far from certain. Banbury evening rush hour becomes particularly bad over the Christmas period. Quite why people feel the need to be travelling to/from the shops at 5pm for the last half of December is beyond me. Why not shop earlier in the day? Come to that why even bother with shops - I buy everything online.

My car lies, it says 53, but does 49.

My Orange Jazz 1.3 SE CVT was traded in last week for an HR-V SE CVT. The Jazz managed 57.8 mpg over 5300 miles of mainly open road driving. The mpg given by the computer averaged 8.8% higher (ie abut 62.9 mpg) with the difference ranging between 6% and 11% higher than the value indicated by fuel bought and miles travelled (I noted the computer mpg at each fill-up). I hope the HR-V will manage about 50mpg under similar conditions.

My previous Jazz (hybrid) managed 58.8 mpg over nearly 16,000 miles of similar driving conditions to that incurred by the Mk 3 which confirmed my suspicion that, for my normal driving, the hybrid system didn't provide much benefit although I would expect a Mk 3 hybrid to do better than the Mk 2 with the motor supplementing the Atkinson cycle end of the revs providing some useful extra torque and reduce the need for the petrol engine to put on the revs.

Hi Guys

Attached is the latest Trip A Screen which is showing my fuel consumption for just over 1000 miles
I am quite happy with the results, whilst accepting the few % optimistic figures.
My Mk2 EX CVT never got anywhere near those figures on a consistent basis.

I note on a previous post someone was suggesting the a larger fuel tank was needed, Why? just how many many miles is acceptable on a full tank, in my view 400-450 miles is adequate. Why tow around unnecessary weight?

I ended up pushing things the other day, fuel gauge said low fuel and by the time I found an open petrol station the car had done some 30 miles from the readout indicating 0 miles left.
Filled up with 39.7 litres, much to close to being a disaster (40 litre tank) never in 50 years of driving have I been that close to "running dry".

Did you do it on purpose as a test ?  If I was doing that I would have a couple of 5 litre cans in the boot,  the Jazz doesn't look like a heavy car but just try 'pushing' one for real LOL

Never knowingly let my tank get below 1/4 full (or 3/4 empty if you are a pessimist).

Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

It was just circumstances, I normally fill before the low fuel lights up.

Do you stop filling at the first cut-out of the pump or keep trying and fill up the filler pipe (my usual technique)? I'm sure the pipe holds another litre or two which probably explains why it's often 50 miles or more before the fuel gauge moves off full. Nonetheless, 39.7 litres is getting close to empty.

Yes the pump clicks off and on a couple of times usually, try to squeeze in as much as possible.

I have just completed a 1,200 mile pensioner roam around. Starting and ending at my home in central Scotland it covered the cotswolds, west country, and London. Always driving at the speed limit, aircon always on, the full to full consumption over the 1,200 miles was 54mpg. The cars info display showed 57mpg. Much was at 70 mph on cruise control, but it included pottering and London traffic. No consideration was given to economic driving, I am impressed.
