I do about 24mpg on my Sharan on LPG doing motorway driving, cold crawl commuting during the week drops it down to 20mpg. Although that is a different engine to you ford boys. I've never run it long enough on petrol to check consumption.

 

Mine is an old mixer system (better mixer will be fitted tomorrow morning) so starts on petrol. I've used about

[mikej]

24mpg on a run using lpg ? thats not a great deal surely ? i normaly get no less than 30 out of the gal on petrol at 70mph ,The loss of power is no great concern as long as it is still drivable.My main concern is trying to justify the quoted Edited March 3, 2007 by mikej

My engine is the VW ADY, from the Mk2 Golf. My car is normally loaded, it's amazing how heavy kites can be (well, 100's of 'em) on the motorway runs, and the pretty stars on my licence probably tell you something :lol:

 

My single point injection is basically a pipe injecting gas into the air pipe upstream of the throttle body. Having had a blowback a few weeks ago, my vaporizer diaphragm is feeling a bit sorry for itself. I've had to richen up the mixture control to compensate.

 

But this morning, I've fitted a proper mixer on the throttle body and the difference is amazing. The mixer puts the fueling closer to the throttle, speeding up response time, and it atomises the mix by injecting in a ring around the air charge. Bernoulli would be proud of it. A quick test drive has shown such an improvement in driveability that I will lean off the mixture and reconnect the Lambda mixture control this afternoon. Then I'll be heading for the 30's.

 

Your modern system will be a closed loop multipoint injection with full mapping. I would expect it to lose very little on consumption and outright power, but maybe even improve driveability.

 

My tank is in the spare wheel well. It's a Stakko 45 litrwe and a bit too small. I rarely carry a spare as my tyres are moused, but when I'm heading for an important appointment, like a ferry or a plane, the spare replace the O/S rear seat and is held down with a cargo net larksheaded to the seat mountings in the floor. It also gives a handy little space in the well of the wheel.

 

The filler is on the O/S rear bumper and the change over switch / tank guage is at the bottom of the dashboard above the ashtray. Getting the whole ashtray out to access the VAGCOM port is a bit fiddly, but do-able.

 

Having lurked around on the LPG websites for a couple of years, I personally would send any work in the direction of Steve at http://www.go-lpg.co.uk/.

 

It will take a bit of time to recoup installation costs, but it's the only way I can afford to run my car. If I had to replace the car, I wouldn't hesitate to look for an already converted car, but if I had to pay for the conversion, I would probably compare overall cost to a TDi.

 

Hope this helps

hi

i have a w reg 2000 2.3 ghia with gas conversion.

sequential gas injection

66 litre tank replacing the spare wheel.

when empty fills with around 47-50 litres. (you can only fill a gas tank 80% full to allow for expansion)

at 46.7p a litre this costs around

[mikej]

Thanks for reply , is this the max size tank you can fit in this location , what system do you have fitted ,who fitted the system and would you recommend them ? by the way the price of your gas is a little steep 39.9 p / litre here in S Wales.

[rojtatton]

was the max tank size for mine.

was fitted by envirogas at tamworth.

yes i would recommed them this is the 2nd car ive had done by them, had a 4 litre v8 range rover with 2 underslung and 1 boot tank prevoiusly.that was the older system and when gas pressure was low performance was low.

new system i sequential gas injection and i cannot tell the difference from petrol performance wise.

My tank is a 77 litre doughnut mounted under the rear end; the spare wheel now lives inside. If filled from empty I get 61 litres in every time plus or minus a little depending on temperature. This costs me around

I can see your keen and rightly concerned. I and many other have asked all the same questions. There are even more questiions now that more experience is about any many users.

I can only give you my experiences which have been in 14 months very positive.

 

I have heard of no horror stories to engines or accidents or serious incidents. Other users always seem positive and critisism only seems to come from a few individuals who dont use it. Maybe Propane does burn a little hotter but to do any damage I think you would have to be at full power for a considerable period to cause any hint of damage to the valves. That means thrashing it at maximum speed (120MPH?) for a long period. What road are you going to do that on in 2007? Who is seriously whose going to spend at least

[mikej]

Well i have now gone and booked the Gal in for a gas coversion after long continplating a change to diesel i thought no ! lets try the lpg route as i am well happy with the Gal i have apart from the mpg.So heres hoping all goes well with the conversion and the desired mpg can be achieved , i have gone for the latest Romano system so hopfully it should be ok.Will let you know how it all goes

Regarding the question of "MPG" lost when running on Gas, I'd always understood that, litre for litre, you should expect 25-35% less when running on LPG. This was based on users experience post conversion, and from a converter. When I posted this information on here, I was told by an "expert" (without any supporting evidence) that this was rubbish. However if you have a look on Parkers and compare Petrol and LPG versions of the same engine you do find a loss in that order e.g Nissan Almera Tino 1.8 36 MPG Petrol, 26 MPG LPG, Volvo V40 1.8 36MPG Petrol, 27 MPG LPG. That 25% difference can push your break even point of recovering the cost of conversion a lot further away.

Form what i have been told by various installers , i currently see no less than 30mpg on a run (petrol) then i should expect no less than 27 mpg (gas) at the same speed this is using the latest kit mind , i have been told the older kits did loose a fair bit but to be honest time will tell .Those who have already converted all seem happy i am certainly looking for an equivalent of 50 mpg after install if not then i won't be happy and will soon let you know.

Hi,

Am new to the forums and am looking for an lpg conversion for my 2.8Gal 2001. I live in Doncaster and am looking for a reliable and recommended installer.Any help would be appreciated

WOW what can i say about LPG apart from i wish i'd done it years ago as i may add a few of you have already said . I had the latest sequential Romano system fitted at a cost of

Hi all,

 

I know this is a year late - but....... i'm thinking of the LPg conversion. My worry is we tow a 5 berth caravan with our Gal 2.3 ghia auto Y.

Do you think i will have to switch back to petrol when towing or is the power loss not that noticable??

 

Cheers

john

[Steve P]

I'd be surprised if you notice - except that the engine will run smoother on LPG - and yes I do reckon you tell the difference in smoothness!!

 

Cheers

Steve

[john mcb]

Hi,

 

Cheers for that - i've just booked it in for the conversion.......on the 15th........i'll report back
