On and 3.2 averages about 25 mixed roads, 2.2 does about 27 mixed roads. Difference is 2.2 takes stuff that only costs 55p a litre.
Cluck me :o

Why are the PFLs more economic than FLs? My two 2.5 petrol manual estates average 29mpg on my mixture of local and Frday M4 runs, whereas the 2.6 manual saloon can only manage 26mpg. I have read it before on this forum that PFLs are more economic. Why?
Its not PFL v FL, but rather 2.5/3.0 v 2.6/3.2.

The newer engines are more compromised to reduce manufacturing costs, the major compromise being the lower CR on the newer engines to avoid the need for an EGR, as Kevin Wood has explained.

This is also the primary reason that the 2.6/3.2 lack the outright performance of the smaller 2.5/3.0 despite the larger capacity.

On the upside, it does make them better for blowing...  ...but you'll still destroy the bottom end quickly.

Thanks gentlemen. That was most enlightening. Now I know why the earlier 2.0s, 2.5s and 3.0s seem superior in power and economy to the later, simpler 2.2s, 2.6s and 3.2s. I know that while the SAI system only functions on cold start up, the EGR system works more often. I wonder what effect blanking the EGR valve has - presumably dirtier emissions.

Not directly related to PFL v FL or 2.5 v 2.6, but some Omegas attract £230pa road tax and others £290pa, depending on date of registration. This creates an 'ideal' used Omega to seek out on e-bay, a 2000 3.0 CDX manual saloon, rust free of course. I recall such a car advertised some while ago, woffle said these 3.0s are reckonned to be the best Omegas, and I did not believe it. I used to have one, and Catherine wrecked it.

You're close, the best Omega is a PFL 2.5V6 CDX is the best Omega to have, in black. With a massive dent on the front wing and door, and a loose sill trim. In black. And the driver's door card in the hallway. In black.

But what's the chance of finding one of them? ::)

Or is this a veiled sale thread :D :D :D

hahaha. Nooo, never selling her. Just that finding another wouldn't be easy  :)


It is said when a Scottish distillery replaced their many hundreds-year old copper stills, they got a copppersmith to actually dent them in the same same place as the old ones, for fear that without, the taste would be altered.

I apply the same logic to my my car  :y

You're both wrong. Start with an Elite (for the better cabin looms) and rip out the shitty suspension ;)

Sounds a bit like a very Rusty Bullet. But we all know you can't be talking about that :-X ::)

I can't believe how good my present 2.6 auto saloon is on fuel although not being heavy footed does help a lot  ::) Decent servicing must add up to something after all  :)

I got 400 miles from each of my last two tanks of fuel. That's brimmed to   showing about 20miles of range.
Probably 3/4 motorway and the rest is mostly town mileage.

It's a 3.0ll auto estate.

Annoys me that I do so much town driving, and most of the journeys end just as the temp gauge hits 90, so my 22.4mpg (as it is now...ah well!  ::)) is not what the engine's capable of. Just under 40 on a long motorway run.  :)

Still, my first week of owning the car I averages 19.9mpg...  :o My right foot adjusted very quickly after that!

I've managed 500miles from a tank in the 3.0, but that was on French Autoroutes most of the way.
