Hi all,

I was crusing auto trader and saw an ad for a 5.0 on an LPG search. Anyway, I emailed them to enquire about it.

The long and the short of it is that the dealership are getting the car converted with Prinz over in Holland and that they will be offering it over here once it's all sorted out.

The dealership was 'Crofton Car Sales'

Thought I'd let you know.

It can be done but being a direct injection it will have to run on petrol as well as LPG at the same time, so not a great saving unless you do mega miles.... Pete

That's what I understand but it's interesting news none the less for the guys that are doing high miles.

My 5.0 drinks like a fish but I don't mind the cost so far as she's so comfortable and has great acceleration!

Anyway, I spend less on petrol than I would spend in cigarettes on a normal work day!

I recently drove a 2017 L405 5.0 SC with LPG - on the route it burned 1.6 l of petrol per 1 mile - that much was spent on cooling the fuel injectors.

1.6l of petrol per 1 mile is that a mistake? I have this exact conversion and it uses about 1l per 100miles Current stable:

Yes, that's a mistake. This engine has direct injection, and even though it runs on LPG, the petrol injectors need to be constantly cooled. Hence, the post-injection rate is 1.6 per 100 miles.

with LPG prices in the UK now over £1 a litre, and the fact that LPG is less energy dense than petrol, which is significant when you need about 1.20 times more LPG to get the same energy output as petrol.

And with our local Sainsbuys selling petrol at £1.25 a litre, it all makes it a bit moot
Added to that - you have the expense of LPG servicing every 10,000 miles at £500 quid a pop, and the savings do not look so great anymore.

NB and throw in the fact that even Morrisons are stopping LPG at many forecourts, and probably will discontinue selling it next year, and so sadly I predict it will fade away in a few years time.

But that’s not comparing apples with apples - lpg has a far higher octane than e10 that you are quoting - you are looking more like £1.40 for that but also those who have an log vehicle would likely be looking to the diesel for equivalence so you are talking slightly more again.
There are still quite a few stations at 75ppl depending on where you live and at 99ppl it’s still just about worth it based on my points above.
When mfg went to 129ppl last year until nobody bought it I agree it was pointless. Current stable:

In Poland, the situation is different: 1 liter of petrol costs 1.12 pounds, while 1 liter of LPG only costs 0.53 pounds. So the difference is significant and the savings are significant.

similar here in portugal , difference between petrol and lpg is worth it and lots more vehicles converted here and lots of lstations still selling lpg

re quote for 500 quid service

12 years and mine hasnt had that spent on the lpg system , and that includes , new injectors x2 , new vapour lines , and a new reducer , admittedly done by myself but 500 quid for a service is to be blunt
