LPG System now completely useless
The system runs lumpy, fells like it's continually about to stall and often cuts out at junctions.
In short, whilst the LPG system is out of it's formal 2 year retailers warranty, (however, not out of the Supply of Goods and Services act implied "reasonable" period), it is now of little use for half of the year.

MORE Problems! Part 2
In short, the LPG system has:
1) Not been usable every winter, despite repeated attempts to resolve
2) Prematurely sent a battery to it's early grave (although I appreciate that car batteries are consumable items and this may have needed to be changed eventually anyway)
3) Caused a cylinder head to crack due to overheating as a result of the water loss. Whilst Z22SE engines have been known to crack cylinder heads, they do this around the spark plug aperture due to overtightening. This crack is on the flat metal of the rear of the cylinder head. This is an expensive problem even for an experienced mechanic such as me. For a non mechanic this may very well mean an uneconomical repair i.e. over £1000 parts and labour.
MORE Problems!
When I took it in to a garage to diagnose the problem, it turned out there was gas getting in to the header tank system (this was diagnosed by putting a lighter to the header tank and seeing the air inside burn quite well!).
As a result of this I decided to get the head gasket changed to be on the safe side (as I thought a leak from the cylinder to the water jacket would cause LPG to blow through, and the car had done 98000 miles so thought it would be this).
Unfortunately this did not solve the problem, so I trotted on down to Autogas99 / Warrington Autogas's new premises, where they changed a seal inside the exchange unit and told me that the water I put in the system was too hard and had caused the seal to fail.

Price Update!
Many places selling it at 106.9 or even 108.9
Gas however seems to be holding steady (for a change). Only 49.9p at Shell Haydock Island (just off the M6) and also Asda at queensferry.

Mostly all sorted now
It turns out that the service is less of a service and more of a "safety inspection" with a gas filter change.
As an amateurish mechanic I could have done this myself, possibly not conduct a thorough and professional gas inspection, but certainly change the gas filter, which I found here http://lpg-kits.org.uk/shop/lpg-filters-service-kits/cat_38.html for £14, so I don't think I'll bother with the services in future.
However, one positive thing that came out of the service was that Andy, flashed my ecu with the latest map. From what I could see happening, it appeared that the new map for the lpg ecu allows it to communicate with the car's ecu more effectively.
Anyway after this new map, there was no stalling, no kangarooing, no loss of power anywhere. The car runs perfectly on gas now, just as if it was on petrol. In fact, sometimes after i've filled up and am still running on petrol, I forget becuase it runs so well on gas now.
In short it's good news, but it should really have run like this from the beginning, given the price. I suppose the main thing is that its fixed now and running perfectly! Now all I need to do is sort out the water leak!

As a little update, having lived with the LPG conversion for about 9 months I can safely say the following
1) I would NOT recommend warrington autogas for a conversion. My slightly unusual car was enough to completely fox them and require many trips back to get it running right. Possibly they have no trouble with standard 1.6 focuses and normal astras, but one slightly different (and my engine isnt even that unusual) car like mine and there was no end of problems.
2) If Warrington Autogas are the best of a bad bunch, I hate to think what the worst of the bunch are like.
After repeated trips to Warrington Autogas I still have the following:
A) Lumpy idling. This does not happen on petrol.
D) The car is still dropping water somewhere. It wasnt doing this before the conversion, so again this is another job i will have to fix.
3) In all honesty, bearing in mind Warrington Autogas were given repeated attempts at fixing my car, they really should have been taken to court for their poor workmanship. All I had in way of compensation was one lousy free tank of gas, which they tried to charge me for anyway before i argued with them.
Andy and the guys at Warrington Autogas are lovely blokes, but there are lots of lovely blokes around, few of whom I would trust to perform extensive and complicated work on the fuel system of my car. Andy and his colleagues are now firmly in that group.
Look at the engine bay after the install.
Note the gas distribution block not secured in any way and free to roam the engine bay.

Other problems
Firstly, the hoses connecting up to the coolant system werent even tightened! So it took me a couple of weeks to figure out why the car was losing all it's coolant. Not only that, one nasty occasion coming through preston in traffic caused the car to overheat, almost getting over 100 degrees (due to the lack of coolant).
Now fortunately I am technically minded enough to pressurise the coolant system to see where the leak was coming from, and i wasnt overly surprised to see that it was coming from the lpg system's additional parts. Had I been an unsuspecting customer I could have had an engine seizure, engine fire, or worse???
What is so frustrating is that I chose warrington autogas because of their long list of satisfied customers. Unfortunately, it seems that paying them £1275 plus credit card fee isnt enough for them to turn out a decent job :-( at least in my case anyway.
I bought a new battery, and it turned out that although the previous battery had held out perfectly acceptably for the past year of ownership (and through a winter period), it was the incorrect battery for the car, being 43ah instead of 60ah. So a bit of split culpability there, whilst i am confident the battery would still have worked without the additional strain of the LPG kit's failings, it could always be argued that the battery wasnt up to the job.
Anyway, I bought a new battery and went to fit it. Joy of joys, where the gas exchange unit had been bolted to the battery tray, it precluded access to the battery clamp. In fact it was screwed to the battery clamp itself, with a smaller than two inch gap to get access to the securing bolts (pictures to follow).
Had I known the lpg kit would have prevented the easy maintenance of user serviceable parts (such as the battery) I never would have had it fitted, and was never informed of this at any time during the installation.
After much swearing, the gas exchange unit was unbolted and the old battery was removed. When I went to fit the new (correctly sized battery), I was prevented from doing so AGAIN!
Turns out the mechanics at warrington autogas had seen the large space in the battery tray (which should have been filled by a correctly sized battery) and instead of thinking "that battery looks a bit small, maybe we should tell him to check it" they thought "thats a perfect place to fit our lpg ecu box!!!", thus preventing me fitting a new battery. I had to pull this out, and rest it in an unideal place to the right of the battery.
I phoned Andy at WA again, obviously unimpressed, and again, I received a load of "well that's strange, it shouldnt be doing that" and "you should be able to get to the battery". To his credit, he did advise me to get it straight in to him and he would try and sort it out so I will report back once I have!
PROBLEMS
Tried to get the cold stalling problem sorted at the 1000 mile service, all that happened was that the temperature change over was set higher, however, this was not the problem. The car was stalling at junctions in cold weather.
The gauge was also not sorted. Instead of reading empty when the tank was half empty, it was now reading half full when the tank was empty.
Also, I did not get any apologies, only "oh god thats not very good" and "yeah thats about standard for those gauges", but as it was the 1000 mile service, and this is when the creases should be ironed out I wasnt overly concerned.
Needless to say, I had to take the car back. This time, Andy (the owner) worked on the car instead of one of his colleagues. He sorted out the problem that I had of the fuel pipes rubbing on the bonnet (surely should never have been installed like that, as he admitted) and of the gas distribution box actually wearing its way all the way through the bonnet carpet (again should never have been installed like that).
Unfortunately, whilst the cold stalling problem was temporarily fixed (i.e. when the temperature was over 10 degrees C the car ran fine, under and it would stall at EVERY junction), as the temperature decreased (as it is winter) it became problem again. So much so that my battery gave up the ghost.

1. The problem with the gauge. It reads empty when the tank is only half empty. Not so much of a problem to me, as I know how to read it now, but it would be nice if it was actually accurate.
2. The car cuts out at junctions when it's cold and the lpgs only just switched over.
I emailed andy at WA to arrange the service, and got a reply back after a few days, so will phone today to arrange a definite time.
Another thing on the to do list is to sort out the boot. Having the 60 litre tank means there is a large lump in the boot floor and I would prefer it to be flat. I think im going to make a false floor out of mdf.

Results
Was slightly worried that my gauge read empty at 120 miles, however, the tank carried on to the 240 mile point without cutting out, so all was fine.
I have the following results with regards to mileage:
1st Tank £22.75 - 240 Miles - Price per mile - 9.5p
2nd Tank* £22.00 - 225 Miles - Price per mile - 9.8p
3rd Tank £25.60 - 273 Miles - Price per mile - 9.4p
4th Tank £26.18 - Not finished yet.
This is compared with a price of 17p per mile on petrol.
The reading for the second tankful was a bit funny because the station I filled up at (suthers star garage at longton), seemed to have a broken pump and after about 35 litres started going really slowly and it took about 7 minutes for the next 5 litres so I gave up at 40 litres. When I asked the girl behind the check out if everything was ok with the gas pump she said "Yeah I think so, noone else has complained; I'll make sure I tell some one about it".
I decided not to bother risking not being able to fill my tank up, so wont go back there!

Day 1
Arrived at Warrington Autogas (WA) to collect my car and was given a thorough walk and talk through the equipment, including filling, operation, and technical layout (I usually do all my own work on the car, not lpg conversions obviously). The technician got in the car before I drove around the block to confirm everything was working ok.
Paid the bill, which, on top of the cost of the conversion had £22.50 on top for a full tank of gas. I received all the neccessary paperwork including the conversion certificate.
They fitted an OMVL kit in the end, which comes with a lifetime guarantee on the injectors (previously a weak spot for OMVL kits apparently), and 2 years parts and labour at WA.
Was very peculiar driving home and not seeing the petrol gauge changing at all! The car is much quieter to drive, and does not seem any slower at all than before. So far, all is good. I resetted my trip counter to see how long a full tank of gas will get me but what is worrying is that it seemed to lose the fourth led (four leds that display the amount of gas) after only 40 or so miles of driving. If this is an accurate measurement, the mpg is less than half what I would get from petrol. I will confirm this by running the tank dry and seeing what the final figure is.

Money Matters
If, like me, you don't have £1275 lying around,you will probably have to borrow money to buy an LPG conversion. I could have used my student loan to buy it, but decided on getting a 0% Credit Card (from halifax) to buy the conversion on. I did this for a number of reasons:
- I wouldn't pay any interest on borrowing the money, as long as I paid it off within the introductory period (10 months)
- If anything went (goes) wrong with the conversion, the credit card company are equally as liable as the converter! I picked this tip up from: http://www.lpginfo.co.uk/. Unfortunately, the author of this webpage got royally ripped off by a rogue trader, but got his money back off the credit card company. Handy tips and guides are on that website.
- Psychologically, I would use the savings in petrol (I usually pay £200 a month, I was hoping to reduce that by at least £80) to pay off the conversion, or at least the bulk of it.
2. The savings
As I said, the 2.2 litre Astra is a nice car, but it's nippy, and I'm 23, so I like to drive it fast occasionally. I also work about 15 miles away from home and my girlfriend lives about 15 miles away as well, so all this means I was spending about £50 a week on petrol. (Therefore about £200 a month). As I write, the sums are as follows:
LPG is about 54p a litre, petrol is now 115.9p per litre so LPG is cheaper by more than half.
BUT! - you only get about 80-95% of the efficiency of petrol with LPG so at best LPG is very nearly half as cheap as petrol.
BUT! (2) you dont only run on LPG, many people find themselves spending about £15 or £20 on petrol each month, as it is best practice to start, and turn off the engine, whilst on petrol.
As I said I was hoping to save £80 a month, this would enable me to pay off 2 thirds of the installation within the credit card introductiory period, I would pay the rest off with whatever student loan I had at the time. Or I could transfer it to another credit card.
The conversion.
Warrington autogas are not LPGA approved, nor do they pretend to be, but the analogy therin is that "would you pay £200 for a bmw service, when a specialist would do it for £50?".
I had also scoured the web, and found many seemingly independent testimonials from satisfied customers, some of whom were on their second and even third conversion from Andy at Warrington.
I had consulted a local converter (local to where I work, literally a two minute walk), but he seemed very dodgy to talk to, and denigrated Andy at warrington autogas. He also told blatant lies (see this forum post I made http://www.my90.co.uk/lpg/viewtopic.php?t=5681)
He also had what appeared to be a dissatisfied customer on the premises waiting to speak to him after I had left, charged £150 more than Andy at warrington and seemed to have a "have a go" attitude with regard to converting my engine, which didnt seem great.
I also (later) read details of him lying to customers when problems arose with their conversions, blaming the car rather than the conversion. For this reason I decided to take my car the 2 hour round trip to warrington.
Romano, whilst not the most premium kit on the market, are far from budget, so it was decided on one of these kits with a 60 litre tank in the spare wheel well. Although this would cause a bulge in my carpet I wanted itto last as close to a tank of petrol as possible. And as LPG only fills 80% of a volume it is put into (48 litres) and is between 85-95% as efficient as petrol, this was the best compromise.
Anyone who has an Astra Coupe will know that boot space is hardly at a premium (2 full size suitcases and one small, without putting seats down, easily).
The filler cap would be fitted in the rear bumper, to avoid irrepairable damage to the body work of the car.
The Car
Welcome!
I decided to write this for many reasons. Mainly, because whilst researching LPG conversions I could not find much information on them or user feedback.
What I did find is (as per usual) loads of people complaining when their LPG wasnt working, but few people telling of their smooth conversion, and great saving.
I have taken the plunge after some research and my car has just gone into Warrington Autogas www.warrington-autogas.co.uk for its conversion, and I have a nice new Ford Focus as my courtesy car.
My next post will tell of how I decided on various aspects of my conversion.
