    Zafira CDTi 150ps - fuel consumption

    The 'book' figures are;

    Urban 36.3
    extra-urban 53.3
    combined 45.6

    My average over the cars first 10,000 miles is 33mpg, during which at least 75% of the distance is extra urban. The best I've ever achieved is 45 mpg on an all extra-urban test run when I averaged only 55 mph.
    I have complained to the dealer and Vauxhall, but am told there is nothing wrong!!!!!

    What do other people get?
    How can I improve these dismal figures (it's noy driving style)?

    Please help - because Vauxhall won't.

    Diesel engines are notoriously tight when they are new and even at 20K they are still considered tight. Obviously this would mean extra effort to really get it going.

    When they do these tests I know for a fact certain dealers map the car to be fuel efficient. They also remove the spare wheel ect. Which means that the figures your getting seems about right. Sorry.
    Its a jam thing

    All I can say is that if you are right it sucks. On paper the fuel consumption should be the same as my old Zafira DTi, but the CDTi has never got any where near it. And if this is the best I can expect, on top of the appalling realibility I have suffered this will be my last Vauxhall.

    tbh I had much better figures from my cdti (sporthatch) than that, it would easily do high 40s on a run, my average never went into the 30s tbh

    Why? The official figures are almost the same. I would have thought that with a bit more power and a sixth gear the 150 would be working less hard then the DTi.

    There does seem to be a growing trend of diesels, especially of the performance variety to fall quite a way short of claimed consumption figures

    I will probably get a diesel for my next car (depending on how much pence per litre is) but i will be doing some serious resarch before purchase to find out which manufacturer is best at delivering claimed consumption.

    I run a 1.9d (prehistoric engine) peugeot small van and my colleague runs the 2.0 hdi version and both of us are struggling to hit 26mpg, nowhere like the figures claimed. Its going to take a long time to recoup the extra cost of initial purchase price over the petrol model, infact in this instance i think it wouyld of worked out cheaper overall to purchase and rubn the petrol!

    Its generally a waste of time complaining to dealers about consumption issues as they will always blame something for it, like your driving style, the type of roads you travel, the wrong type of grass growing on the verge etc.

    As jam says, hopefully things will improve when the engine slackens up a bit.
