When you put it that way, you do see the saving LOL

Funny thing, it felt like it had a V8 on petrol, on gas it felt like a 300tdi auto RRC

I'll get it fixed,,

One day

It shouldn't feel any different at all, the only way you should be able to tell what fuel it is running on would be to look at the switch. Look at it this way. If it costs you £200 to get it sorted out, if the 400 miles is a month, you'll have recouped the cost within 3 months and after that your costs would be almost half what they are now.

I don't exactly remember what it did to £40 on pez as i always filled it on payday..

£132 would get me 407mi which wasn't too bad.

That would equate to £32.43 per 100 miles on petrol then.....

I'll sort it so it runs just the same on LPG as on petrol Strangerover.

If work isn't close enough to be almost as quick just to walk there instead of drive there you should be saving some money by driving to work on LPG instead of on petrol.

I'm sure I've said multiple times on this forum that I fitted your LPG system yet nobody corrected me (on the fact Profess fitted it)!

Profess used to try to get customers to buy a Stag interface cable from them, they try to give potential customers the impression that they (and/or the Stag systems they fit) are unique in that they can be remotely diagnosed/repaired/serviced by Profess accessing the LPG ECU via the internet. The truth is that any installer of just about any LPG system could connect to just about any LPG ECU remotely over the internet using the same method that Profess uses - courtesy of Windows remote desktop access software! But what Profess don't tell customers is that they're very likely to need to make use of this facility in their case because they didn't calibrate the system properly in the first place. It doesn't help that they take shortcuts in installation and don't have a wide range of bits available to them so couldn't pick and choose between components even if they knew how to... because they only fit Stag, but their reliance on autotuning systems is one of their biggest downfalls.

I do well with LPG conversions because I know the real world specs of different components, how to pick and choose components to best suit a vehicle, don't take shortcuts during installation (try to get the setup, which is the base of a good install, as ideal as possible) and go to great lengths to calibrate everything properly while keeping in mind how temperatures in different seasons (etc) will affect things. If I'm not happy with any aspect of an install when I see readings etc during calibration I'll go back and change things, sometimes even major components, to make things right. But a P38 should be an easy bread and butter conversion.

I've heard people say this before, Oh it's got LPG fitted but I never use it as it doesn't run right. Now if you are talking about something that does 40mpg then running costs probably aren't that high on the agenda but on a car that can't even manage 20mpg, then you are simply pouring money down the drain. If the 400 miles is in a month, then getting the LPG system working correctly means another £55-60 a month in your pocket to spend on beer and women or waste it on more bits for the car. I never even think about fuel costs, I use my car as much as I want to as I know that when the tank is empty I'm only looking at another £35 to fill it again.

While we are on the point, what are you doing to manage to get it reading as low as 1.6mpg?

You can get it to read even lower if you really want to. All you do is start the engine, reset the trip and leave it idling without going anywhere. In theory you should be able to get a minus figure but you can't.......

Actually, pretty grim.
I buy gas at 52.7ppl right now and get an easy 170 miles per tank even when thrashing the thing round country lanes on a 7 mile commute. With a 65 litre fill that's £34.25 per 170 miles and all those figures are worst case apart from the price which is correct.
Petrol consumption is absolutely minimal, I waft out of the estate on petrol and it changes to gas just after the NSL sign. That's no more than half a mile.

On a motorway trip, 200 miles is quite possible as Gilbertd says.

I had a guy here the other day with a Subaru Imprezza WRX converted with a Stag system (I believe fitted by Profess). He came to have me disable the LPG system (wiring and piping), the car was running on 3 cylinders due to bad compression likely due to VSR and was due to go into a Subaru specialists to have the engine rebuilt but the specialist wouldn't work on the car with the gas system connected to the engine, even with gas pipes disconnected wouldn't have wanted to cut the injector break wiring to remove the engine.

The installer hadn't fitted any type of lube system (WRX really needs an electronic forced type) and the car had always been down on power (I suspect due to running lean at high loads)... both lean running and lack of lube system would have caused VSR. I haven't looked at Profess' website in a long time but they used to have a blog on the site, in the blog they reckoned they didn't advise lube systems for any vehicle.

The customer said he may return for the LPG system to be fully removed after the engine rebuild. I told him I could get it running great on LPG with a few component changes, the engine would live a long life if I set it up so the LPG system provided correct fuelling and with an electronic lube fitted. He says he'll think about it when he's had the engine fixed but will be seeing me again anyway either to have the LPG system totally removed or to have it sorted.

I liked the trip computers in my old Vauxhall Senators, when moving they'd show current or average mpg, when stopped they'd show gallons per hour (which obviously also had bearing on average mpg, same as when other vehicle computers just show 0 mpg but possibly more accurate).

I had a Golf showing 200.00 mpg weekend before last. Not sure what mpg the Series III in front that was towing it was managing, but suspect it was nowhere near that.

That's great Brian. I suspect we could see that kind of mpg on our P38's with the right tow vehicle. But I'm not sure if towing an awd vehicle with the wheels turning is a good idea.

The savings are real i agree, the system was fitted by the PO i had no say in it!

from 2003 - 2013 she had a single point LPG system fitted by "someone" her reg is BV51FDG/H19OAK so if you have records Simon then that would be her.

from 2013-present it has an AC Stag system..

Thats a good point..

I appreciate the benefits and will get it fixed when i can :)

I've checked records going back to 2008 which is when I generally started keeping logging numbers of vehicles I've seen, nothing comes up for either reg number but it could be one I haven't logged the reg on or one that the owner wasn't bothered about a receipt for a service etc on. Back in the day I sometimes converted 10 P38s in a row and saw many others for servicing/repairs.
