Guys,  i had a guy pop round today delivering our tiles for new kitchen blah blah, he noticed my Omega on the drive and said nice car, i used to have one, i said yeah... i cant afford to run mine with the price of petrol at the moment, he then says that i should have bought the 3 litre engine and not the 2.5 V6,  i`m like WHAT???
bigger engine more bloody fuel surely!
my Trip computer says my cars doing 32 mpg, is he talking a load of ol gumf??
he also says the 3 litre version is quieter inside on motorways, is he insane?  lol :-?

[duggs]

Yes and ermmmm No !

Whilst it is true imho that fuel consumption is better on the 3.0 if you drive like Miss Daisy it sure isn't if you're heavy footed.

Otherwise fuel comsumption wise, on a day to day basis, a combo of around town and open road driving I've noticed no difference between my old 2.5 and the newer f/l 3.0.

Does the 3.0 litre cruise better than the 2.5..yes I think it does. Quieter only because the revs are a tad lower at any given speed.

Does the 3.0/3.2 sound better ?...Ooooooooooo yeah !

I'm running a 3ltr elite estate & 2.5ltr saloon

The 3ltr is slightly thirstier, but nothing major. Like any car, its the heavy right foot that makes it more juicy!!

I hardly notice any difference between my 2 TBH.

In my opinion the 2.5 engine is the right size for the Omega..

It will do more miles to the gallon than a 3.0 I have had several not one yet beats the old 2.5 Mrs Loo-knee had.

As for the noise whatever I think he is tslking out of his arse mate

My 3.0 did 18mpg, my 2.6 does 22 mpg

[2woody]

I'm running four Omegas at the moment, the 2.6 and the 3.0 auto are markedly worse on fuel than either the 3.2 or the 3.0 manual.

driven in exactly the same manner, the 2.6 manual will average around 26, whilst the 3.0 manual averages around 29.

no great mystery, as the 2.6 is much "shorter" geared.

incidentally, my 5,7 Commodore is more economical than them both.

[duggs]

I'll go with 2woody...whatever he said !

Wife's always complained that i'm shorter geared !

On reflection that doesn't sound like a compliment.

you want LPG, my 2.2 does an effective 55mpg
