MotherT's new diesel is averaging 50+ 

I still find it staggering that some get mid 30's from 4 pot diesel, a JagXJ diesel will average mid 30's

[Stemo]

My wife's 1.6 petrol gets 38, my 1.8 gets 28 and I only do town driving.

[05omegav6]

My next car will likely average about 32-33 mpg, but I will be able to get Stemo, a roll of carpet and a shovel in the boot without blinking

Diesels are great if you own a bus, lorry or taxi. 

35.4mpg

Got the first brim to brim figures from the Battlebus (I can't find right config for the GID ), and can beat your Insignia...  ...by 0.2mpg, 35.66mpg

200 miles of that tank was a 75mph jaunt up the M1, so was expecting better, though 100 miles was ragging it around the hills on North York Moors.

Lower than I was expecting, but then it has got something fundamentally wrong with it.

So...have you ever thought of buying a 'newish' car, say three years old, that doesn't break down all the time? You'd get a decent mpg then. Just a thought.

You'll never learn will you. Why buy a newer car and lob away 15k in depreciation, when you can fix something older, hopefully

Because you should not have to fix every couple of hundred miles

Can it 'dangle berries'! Not driven properly. Mid 20s.

The battlebus engine, GM's 2.0DTi from the late 90s, wasn't a particularly great engine when launched, but any 2l diesel from that era will be 100bhp, and realistic 40mpg.  The common rails that followed around 10years ago managed much better power and economy.

The exception from the mid 90s was the VAG 1.9, a very good engine in its day for power and economy, and can still hold its own today (unlike its rather poor replacement)

Same can be said of the Peugeot lumps too, although the 1.9 wasn't particularly refined iirc

Never rated them myself...

Pretty reliable, especially given the 'french' influence, very economical too given their low tech nature

[Vamps]

  Or mine. 2500 rpm is my usual cruising speed, and I have a high diff.

The magic figure.... I tend to keep to this in the Jeep, gives a cruising speed for around an indicated 75 MPG and leaves another 2000 more rpm if needed.............

Now you see why people have diesels

OOP's..........   As those reading it will know, I meant to say 75 MPH............

My Signum averages mid thirties and that's 3.0 v6 and auto

Yup, and the early XJ's had a 2.7 lump I think, later on a 3.0.

Given Josh's 4.2 V8 XJ did better mpg than my 3.2 Omega, not hard to see diesel XJ getting mid 30's

Josh's 4.2 XJ would manage mid teens at best, driven properly. Probably an easy 30mpg on a nice sedate motorway cruise, matching a 3.2

In the same way, I can achieve (on petrol) low to mid 30s from a 3.0l auto Omega. Normally, its nearer low 20s (on petrol).

[05omegav6]

To put this debate into perspective, the current and previous XJ are both Aluminium, not steel, so are a fair bit lighter

The diesel V6 is great, right upto the point where you remember it's French

Also, regardless of claimed mpg figures, real world economy is generally 20% lower

Not what the MID said in his 4.2 V8
