LPG on a 2.2 auto
« on: 02 February 2010, 16:11:24 »

After much research on here and a few helpful pms, I'm thinking about getting Trigger's Broom gassed  :o

Anyone else got a gassed 2.2 auto?

What is it like-any power difference?
Real world mpg on gas?
Is it worth doing on a 2000 car with 102k miles?
Will it increase the value?
LPG 65p/litre here-how many miles until cost covered?
Need bootspace-what is range of donut?

Does anyone have a secondhand donut tank or full kit?
How do I get the certificate?  Where?
Anyone fancy the job or had a good pro-job done? Cost?

Thanks to Lazydocker for pm advice so far  :y

KenT has, not any different to manuals

What is it like-any power difference?

LPG is a higher RON than petrol (its about 105) but the knock sensors don't take affect, overall it should be about the same, with maybe a slight loss. Cheaper kits can stuggle at very high RPM's (5.5k+) Stag kit does very well, the bottle neck is the evaporator, make sure this is rated to at least 140/150 bhp

Quote
Real world mpg on gas?

20% - 25% less than petrol

Quote
Is it worth doing on a 2000 car with 102k miles?

Yes i plan to do it on my 2000 133k mile 2.2

Quote
Will it increase the value?

This causes dis-agreements, i say no over all, as you are limiting your market, people want the space an Omega has, most likey go up a bit, but not enough to get conversion costs back

Quote
LPG 65p/litre here-how many miles until cost covered?

Shop around, its 64p at BP near me, its 49p at Asda  :o

Quote
Need bootspace-what is range of donut?

200-230 mile range on donut, causes issues reaching rear bulb cluster  :(

Quote
Does anyone have a secondhand donut tank or full kit?

I would get brand spankers, i got the whole kit, tank, injectors, pipe work, for £500

Quote
How do I get the certificate?  Where?

Not sure on this, you need to take it to someone to test, who gives you an all is well and safe bit of paper

Quote
Anyone fancy the job or had a good pro-job done? Cost?

£500 parts + beer vouchers DIY

£1,000-£2,000 - 'proffesionally' but many garages make a real, hash of it.

Cheers for that  :y especially range and rear light  :y

Now need to work out how to get money, then find a good cheap kit, then chat to Lazydocker-he's been so helpful, but is a busy man and we are looking at plans, any offers appreciated!

£1000-odd will pay for itself in 12 months, so the sooner the better.

My fear is spending the money and the car getting bumped and only getting minimum trade value back.....losing the huge amount of work already done and also the LPG work.
After two years, the whole car+works+LPG spend will have been covered by the use it has given  :-/

sadly it is a risk, my worry is that mid conversion it will get struck or something  :-/

DIY is best route, limits any potential loss  :y

The obvious point is after doing all of this work, I must keep the Omega for a good few years, but the economy is killing me.  If I can get a good, cheap gas con done, then it will be the best car for my needs-it will be paid for, reliable and offer bearable running costs.  At 45-50mpg equivalent it will make me fully happy with it and stop looking at alternatives.

Just need to find £££, kit and arrange to get fitted somehow  :y

Fear not Geoff... We'll get it done sometime :y :y :y

Of course... If you can do weekdays instead of weekends it fits much more easily with my work commitments.

I know mines a 3.2 so totally different ... but I've not bothered with the mpg calculations as IMHO they tell you nothing.

I work on "pence per mile"

Now on petrol I get around 20 mpg average (I do a LOT of towing) and with petrol at £1:11.9 a litre that is £5.08 a gall, it is 25.4 pence a mile in fuel costs.

On gas I get around 16 mph and it is currently 58 p/litre or £2.63 a gall which is 16.4 pence/mile so I'm saving 9 pence a mile.

or look at it another way .... not quite half the cost of petrol !!! (its about 38% in my case)

as I do about 12000 miles a year .. 1000 a month that is a straight £90 a month saving.

Now I actually have the figures for nearly 2 years and as prices rise and fall, and so does consumption depending on driving style and/or towing ... the actual savings over 2 years average at 9 p/mile .. which sort of proves my figures ...  but I have saved over £1700, and I don't do that many miles now, compared to when I had it fitted.

Your figures will differ, but IMHO the best way to do the calculations is on the cost per mile basis.. :)

Now if you do your long trips .. you save even more as I believe LPG price in Poland is very cheap

I have LPG on my 3.2, 80 litre tank in the boot and still loads of boot space. I have absolutely no difference in power and can't even feel it change between petrol and LPG. I get just short of 370 miles on a full tank of gas that costs me £40(ish) i couldn't afford to run my omega if it didn't have LPG, but with it, is very cost affective, no congestion charge in London either.

One thing, i used gas from one garage and only got 250 on a full tank, BP always gives me max mileage, so shop around.

Is that an 80L tank (65 litres to fill) or 80 litres to a fill (100L total tank capacity)? Because 370 miles sounds too good to be true.

Very useful-cheers :y

LPG in Poland is about 40p litre-much cheaper than petrol

I didn't think any Omegas other than the factory fit 2.0 wer on the Powershift Register, which is the only way to get exempion (or have they changed that) :-/ :-/
