When driving my Octavia at around 30-35 m.p.h in fourth gear the indicator comes on to advise me to change up to fifth gear and then when I do it doesnt seem that happy initially, but at other times I can drive up to 60-65 m.p.h.in fourth gear, just to test it, and the change up to fifth indicator does`nt come on.Had its first service today and mentioned this but was advised that nothing was wrong with the car, all my fault for taking too long to change gear,of course,why did`nt I think of that, my fault all the time.Another thing is when I have the fuel consumption showing and driving on the motorway it goes up to 80 m.p.g. then 90 and on sometimes up to 105 m.p.g., just like running on fresh air, but no answer was given for that, probably my fault again for driving it on the motorway.

Bristol VR3 thats an odd username, nothing to do with a bus is it? i.e. Bristol VR series 3??

If you're driving reasonably sedately the gear change indicator likes to tell you to shift up early. If you've put your foot down it realises that you're not pootling about so it doesn't recommend short shifting. If you feel that changing up too early will make the engine labour then just don't bother - the indicator is fairly simple, it's not perfect (it can't tell if you're going uphill for example) and it's not supposed to replace your own common sense and driving experience.

With regard to the mpg reading, I assume you're looking at the instantaneous mpg readout rather than the average mpg readout. If you're on a very light throttle, or no throttle at all you will be using very little fuel hence the high readouts. Put your foot down and those high readings will plummet. It all averages itself out, and that's what you'll see on the average mpg readout.

I realise that common sense and driving experience, of which I have 40 years are, are useful but as the car was new I was inclined to do as I was indicated to rather than drive my own way. Thanks for the explanation anyway , shame that the service technician could`nt explain it so simply instead of blaming the way I drive. Bristol VR3 is a name that I have used for a long time,I used to work at Bristol Commercial Vehicles Ltd., when they were making Lodekkas,RE`s and VR`s.
