Hi All

Anyone with a 1.3 CDTi 90 what sort of MPG do you reckon you are getting. I have the plus pack fitted so have the onboard trip, I think it's telling me lies as it never goes over 39MPG. I now have 760 miles on the clock so it must be getting about run in.

I reset the trip last time I filled up and I will calculate the MPG manualy to see what I am really getting. Just wondered what you guys were getting in your and can you get anywhere near Vauxhalls claimed 60MPG (I know you have to drive like grandma to do that!)

In all honesty I think you'll have to put a LOT more miles on the clock before you start getting optimum MPG.

I've had my 1.7cdti 3 months now and the MPG is slowly improving but nowhere near the figures quoted.

Friends I've spoken to say it took their various makes of diesels a few thousand miles before the engine settled in so stick with it but expect a good 6 months of motoring before the old diesel engine beds in.

my 1.3 90ps loan car is as bad as the 1.4 i had before getting about 280 to a tank tho there is only 1000miles on it. The mpg figures quoted by vaux are utter sh1t. my 1.7 was woeful as well

the newer engines need a few thousand miles to bed in.. for some reason some might need upto 10k.. :\

Mines just about to turn 50k on the clock (1.7 CDTi C) and i have currently got 550miles out of a tank.. with a little left!

You just need to be patient with the engine as it beds in.. the more miles on the clock the better the mpg will become.
But it also depends if you alot of urban driving or motorway stuff too..

Just woked out my MPG. Done 296 miles on a full tank and worked out the MPG to be approx 35 MPG.

Pretty bad really, however I have been drivin it hard this last week. Will take it steady and see what it returns this week.

TBH.. i found the 1.3 curtesy car i had when my C was having the fuel pump replaced just DRANK fuel.. 90miles to a 1/4 tank :| (thats with nearly 8k on the clock..)
My 1.7 does 110 to a 1/4 without trying.. :\

But it might take a ALONG time to break the engine in to get its best MPG, but knowing the best millage is unknown as every engine is different!
