For 2 1/2 years (since the car was new) ive been questioning the fuel consumption figures, the best my self and the vauxhall garage can get out of it is 41mpg (the official figures are 53mpg). Vauxhall have had the car back about ten times and changed a variety of parts but no improvement, they are now saying that this mpg is exceptable.
Has anyone else got any experience on this or owns a zafira with good/bad consumption?
kind regards in advance

Your consumption sounds about the same as mine. It's nowhere near as good as my old 406Hdi estate. I guess that it's due to a combination of poor aerodynamics and old engine technology. The Hdi was also much more refined than my Dti. This may explain why Vauxhall have dropped the old 2.0 Dti engine.

If they really did think it was acceptable then they wouldn't have had it back 10 times.

the official figures are 53mpg
Obtained in laboratory conditions, but rarely replicated in real life.

understand that dave but 25% down is a bit much!!!!!!!!!!! Vauxhall achieved the figure of 41mpg by driving it at 60mph for a hundred miles on a motorway, basically the best style of driving you can get for consumption. they've agreed with me all along that its low otherwise they wouldnt have kept having it back and changing stuff, so to turn round now and say its exceptable seems a bit odd. Also looking at reports on the net from other drivers they seem to be getting high 40's

Out of interest, how many miles has it now done? I'm asking because although it's 2½ yrs old, if it hasn't done *that* many miles it could just be a case of the engine hasn't yet fully bedded in.

By comparison, I average 38 to 42 mpg (more if all long distance cruising) from a 2006 1600cc petrol Zafira in mixed driving.

19k miles in 2½ years. That's...nothing!
Your engine may only now be loosening up. But only if it has not been used sedately. Do you use the full range of the engine revs? Do you redline the engine every so often?
The following is a stereotype
Carefully driven, one lady owner, 8000 miles per year, local trips are not good for engines. They remain not properly run in and are often blighted with carbon deposits, leading to lower mpg.
All new diesel cars start with low mpg. If all are driven in the same manner, some will loosen up sooner than others. This is due to the engineering tollerances in engine production. Perhaps the individual component tollerances on your engine caused the whole engine to be slightly 'tighter' than the average.
