On the 2.2 subject, see you brought this one up  ;D,  I did have 2.2 Manual LPG to drive around in for a little while, and was quiet surprised how bad it was on MPG compared to the LPG'd V6's Ive driven. :o  ;)

Consistent 27mpg I would get, never really had lower than 22 over an entire tank. Record was 31 on long run, all LPG figures.

With 3.2 getting 23/24mpg on petrol, I would expect around 17/18mpg on gas.

Absolutely, I never saw the right side of 30 on mine, I think I once got 31.5 on the SID, but that didn't hit the magic number brim to brim.  I'm very tempted by the 3.2 in a vectra or signum to LPG as I understand its an identical engine (although clearly the gearbox will be different). However I need a garage to work in before I can do that!

For the short time I had the 2.2 LPG bearing in mind its a Manual, I used it for a week or two for London commutes, thinking I would save myself a fortune, did a few brim to brims on LPG, which is how I always calculate MPG in real terms,  it was doing on LPG about 22mpg on average in the smoke, my 3.2 LPG'd Manual would do them sort of figures, in fact a 3.2 LPG Auto wouldn't be far behind, I reckon 18/19 mpg.

On the Vectra Side Ive also got one of them, 3.2 Manual Elite LPG'd, there not too bad as it goes, never as comfy as a 3.2 Omega (or any quicker) but could hit 24 in Town and 30+ on a Motorway using LPG, probably get rid of it in the New Year as dont really use it much these gays if Im honest.  :-\

Funny you should say that about comfort, I was eyeing up swapping in some omega elite leather chairs (or even CDX manual heated leathers) into the front of the vec if I got it, not sure how well it would work though  :-\. Given the electric seat switch gear is the same across the two vehicles, I'd be amazed if they don't share a lot of common components.

Omega seats will never fit Vectra C. Best option is the ultra rare memory fronts from an early Signum ;)

never seems a bit strong. You might have to do some fabrication work to match the Vectra runners with the Omega seats, but that's hardly complicated. Having put Capri seats in Minis, RS Turbo and Probe seats in Capris, Scorpio seats in a Superminx, Vectra in an Avenger, Starion in mk1 Escort and my Metro has Astra GTE seats I reckon this sort of thing is easy. Unless you expect bastard combinations to just bolt together.

They mount completely differently  ;)

Vectra C seats hook in at the front with a bolt at the back of each rail...

Alot of work when you can buy something that bolts straight in ::)

Sh!t figures.  :D

3.2 Auto Saloon, London commute of 25 ish miles from Surrey. Mixture of motorway, city and heavy traffic = 24 mpg average.
I suspect few others could achieve that.


To the OP, pre LPG, my:
3.2 - approx. 21mpg day to day, 30mpg on a clear 80mph long motorway cruise, mid/high teens if I had a lot of fun over the tank
3.0 - 24mpg day to day, 35 on a clear run
2.5 - 27mpg day to day
2.5 chipped with 3l cams - 25mpg day to day

Currently 22.9 over current tank, which is almost out, think slowly I'm getting that binary throttle control  :D  ;D

I think even if you did manage to get them to bolt in I'd doubt whether you would be able to shut the doors, there wider then the Veccy seats.  :-\

Yea, the 22mpg on Gas was with a lot of stop starts, probably more stopping then starting if Im honest in Central London.

17/18 mpg 3.2 Auto on LPG, yea I would agree with that, what did i say above 18/19.  :y

The way I would look at it, getting LPG sub 60p, would be even 15mpg is basically 30mpg in terms of cost. So why not have a heavy right foot!  :D

Shell on M3 Sunbury though clearly don't want LPG on their forecourt any more, 65.9 when I drove past last week.  :o  :(

Yep, around town I see about 17 mpg.  The longer the journey, the higher that figure becomes ;)

More, a lot more, lets take your 3.2 and your commute to work, I'll base the Cost on around here because I know the Prices, Petrol at 1.229 perL, LPg around here is 53/54p, lets call it 55p perL, if you doing 24 MPG with your right slippers on then you should easy be able to do 20/21 mpg on Gas but lets call it 19mpg .

So Maths based on current Petrol and LPG Prices.

Gallon of Petrol £1.229 L x 4.55 = £5.59 Gal, / by 24mpg = 23.3p per Mile.
same cost on lpg
£5.59 worth of Gas / by 55p = 10.16 L, / by 4.55 = 2.23 Gals, x 19 = 42.4 MPG equivalent and 13.2p per Mile   :y

Plus, as you already know, where your really going to see the cost benefits of LPG is on a nice long Run where you can push your average MPG up even more ;)

Yup  :y :y :y

I must try and pop the cills off the 3.2 this weekend, to inspect for rust. See how it's looking before committing.

55p would be a challenge this side of London though, BP at Hatton Cross would be my main filling location. Hopefully they still offer that LPG accumulator thing, as they currently offer it at 61p
