To the op - I've owned a 3.0l v6 auto and a 2.5td auto at the same time. Nothing between them in running costs, day to day.  If you must go diesel, it really, really, really has to be a manual. And chipped.

I was getting 24mpg from the 3.0l v6, and 28ish from the TD on my (then) 50mph, 23m commute in. Diesel is more expensive, and has higher servicing costs.

Are the 2.5td that bad ? I fancied one as they burn on veg but I know I would miss the v6 despite it oil leak and rough running

That's quite normal!  ::)  ;D

Think you need a session with a Tech2 to check it over - have you had the emissions checked?

Could be the coolant temp sensor, not the one for the dash but the one for the engine management.  If it's reading low, it'll be over-fuelling.

My 3L manual was quite easily be persuaded to give just over 30mpg on my old 15 mile each way trip to work.  On a motorway run cruising at 70 it will hit just under 40mpg, and that's with a 3.9:1 diff instead of the correct 3.7:1 diff for a manual V6.

My M5 won't get anywhere near that even if you're towing it.

so my low mpg isn't normal then , before i had kids , i had a classic impreza wrx uk 2000 that was only running 242 bhp an that did 19 mpg an my other bug eye impreza was running 285 bhp an made 18 mpg , after i sold the pair to make way for a family wagon as my wife wanted to breed i bought a vrs estate running 230 bhp an made 28 mpg ,
so was shocked with the 16 mpg from the 167 bhp slug .
have had it in to a auto electrics garage a mate works at an plugged it in , an other than the air bag light that i know about , all was well

Are you doing mostly town/city driving?  I have to say that the Omega auto box is horribly inefficient, probably due to the 1980's technology it uses - Carltons and Senators used the exact same box  :o the only update was to add a 4th gear which you won't get anywhere near using in town.  And the torque convertor only locks up when you get over 50mph.

Has the gearbox software even been updated - not that it would make a significant difference to economy anyway, it's more of a driveability improvement.
