Hi guys,

Considering the purchase of a car with a stag LPG system installed.. Car is a 4.2 V8 audi lump

Stag seems to be at the cheaper end? So not sure to be more concerned? It's a vehicle through the trade, so not able to talk to the owner to find out specifics.. Car will be sold as trade, so no warranty... So need to go in eyes open.

I understand the vehicle comes with the Invoice and certificate of fitting etc, I assume insurance companies need this? Do the insurance companies generally ask for any evidence of service/safety check I. The last 12 months? I assume not.

In some ways having the conversion is a huge plus, but I guess could be a nightmare if it wasn't just right, and I guess could have caused engine issues if incorrectly fitted etc. if it starts, runs smooth from idle cold.. Through to fully warm, I guess within reason that's it.. How do you know when it switches over to lpg when running?

I will also see if anyone in my area (n Ireland) do stag systems, no point buying it if not.....

I don't have any knowledge of stag. Basically you have a second fueling system nad everything that can go wrong with one can go wrong with the other.

Insurance companies can ask for proof of a professional install, and may get arsey if you don't havethe certificate. You also need the certificate for registering it as duel fuel to get the 'tax disc' discount.

You may have to pay for a certificate if you don't have the original with the car.

Insurance is a lottery with LPG, When I converted mine I actually got a small refund. The issue seems to be with the 'price compare' websites that just treat LPG as a modification and rate as such. I've found it more productive to do direct to the companies.

I'd be wary on a cheap install with no certificate, but going in with your eyes open and at worst you can just switch it off and run on petrol.

A full install would be 1500-2k, and that covers the system, the tank and the injectors, and labour. I would guess the weak area of a cheapy install would be the injectors and it wouldn't be too expensive to fix that. Also get it serviced as its surprising how many people think its fit and forget.

Thanks!

Yes, I will defo check to see whether there is a local stag dealer/engineer to checkit out and service as needed..

Interesting on the tax too.... S the car should have a reduced tax, which is particularly interesting as this one will currently be in the just under £500 a year... I will ask to see the cost of the tax on it currently..

I changed from a v6 Alfa to a V6 Omega(lpg) just a few days ago and my insurer (Swiftcover) say they don't need to know about LPG installs and when the change went through I got a £38 refund!

Most of the big price comparison sites have a modification option where you can declare LPG up-front. For the ones that come back rejected it might be worth picking the big insurers and doing a manual quote just in case their system wasn't set up to take modifications from the price comparison site. I have been charged £20ish extra once that I can remember, certainly nothing to worry about.

I haven't ever been asked for installation details for mine, but it is registered with the LPGA - you can search online to see if a vehicle is registered: http://www.drivelpg.co.uk/

ive had 2x stag installs -no probs with either in over 50k. it ALL depends who installed it and how good at it they are! a great system installed by a buffoon will be a nightmare. a cheap system installed by a competent person will be fine.

Stag are -in my experience - only serviceable by stag people. Other systems seem to be serviced by anyone anywhere... not sure why. However you can buy a USB thingy and service it remotely nowadays. changing the fuel filter isn't hard either...

Agree 100% with this. I've just had a system fitted after having it when I bought my last car. The fitter is the important thing. I searched long and hard and met several folks before I chose the one to do mine. In the end I chose a well respected marque forum member who'd got loads of references and does lpg as an aside to his day job as an engineer.

A question about servicing, changing filter looks easy. Exactly what else is required, something ecu related? Judging by the 'usb thingy' comment?

Sage advice there.
Even make contact with a local LPG installer and give him a few quid to do a check on the LPG install. Then use him to service the LPG for you. I get my LPG serviced about every 6000 miles, takes about an hour

The STAG systems are generally as good as anything else on the market. Remember the "system" is only really the ECU part - you can combine one make of system with lots of different tanks, reducers, injectors etc.

yeah the service is actually a laptop, a bit of software tweaking playing about with some sort of curve on a graph, and not a lot else! That's why you can do it remotely. It's all about electronics. The other bit I suppose is a visual check for damage, but ANYONE can do that with a torch and a pair of eyes. Maybe even just one eye...

Don't work in the motor vehicle LPG side of things, but do work in the industry . Would strongly recommend that amateur gas engineers leave well alone. A pity in a way that the LPG motor industry is not subject to GasSafe ( the new CORGI) regs.

It sort of is. The install must be certified by an approved installer to get on the LPG database. Yes ok you could run it without being on the database, but both my insurance company and the dvla have, in the last week, told me they needed to wait until its on the database to check it's professionally installed before changing the system!

My amateur guy who does lpg on the side was way better than all those doing it as a profitable business. He took great care and pride in making sure everything is properly secure and looks as oem as possible. He is a time served engineer so works to microns for his day job. I've seen so called pro installers who tie wrap injectors in place as it's faster.

My guy then paid to have it certified at a local installer. They won't risk their reputation unless the work is good.
