LPG Conversion C43 AMG

[SimonsMerc]

- 20% less economical than petrol

Expensive

- smallish donut tank = more trips to the pump

More expensive

- you can tell greenies to go jump if they critise you for owning a 4.3 v8

Priceless!

Good post

explain how its more expensive? if I'm paying £2.00 per gallon and get 80% efficiency compare to £4.40 per gallon on petrol thats still twice the distance I'm getting for the price of a gallon of petrol.
The cost of installation is expensive and people keep going on about time to recoup revenue but if you is not a taxi driver or sales rep then that doesnt really matter that much. I convert mine because I like to drive the car and running on lpg means that my milage increase because I wouldnt think twice to drive from bham to london just for the fun of it whereas if I was using petrol I would have to have a good reason to do that. The 20% reduction you dont notice unless you have a 1.0L ford Ka or something like that but if you have a car >1.6 you dont really notice that diff unless you have a larger than average significant other (wife,girlfriend)

Oh I forgot to mention one disadvantage of running on lpg, The engine oil never change colour so you have to remember when you had change the oil. when you run petrol or diesel and you chech the oil level the colour is there to remind to to change it but the lpg run so clean there is no contaminant in the oil

So why change it then? Why not have an oil analysis performed to check for contaminants.

Fit a bypass filter and you will never need to change it anyway.

But not as opposed to a diesel for instance, and if you run that on Bio diesel at 79.5p you save an additional 20% anyway.
So twice the distance per gallon and 20% saving is better than the LPG probably with no additional cost or loss of performance.

Well, after 2 months since my brothers LPG conversion of his 2003 Audi A8 (4.2 V8) I can report he is very happy with it.

The only diffrence in power appears to be less than a second delay once when you floor it from a standing start.

The conversion has been done very well, the filler nozzle is next to the fuel filler hidden away, so apart from the bbq fuel smell you cannot tell its been converted.

There is an LED fuel indicator fitted nicely on the centre console which isnt that accurate - so far thats the only problem.

Due to the A8s boot being larger than Germany, he opted for the tank in there not a dougnut tank, which still leaves a hanger size boot.

We have calculated it will take about 12& 1/2 months to pay for itself - so 10 months left.

At around 43p a litre, I wouldnt dismiss the idea before you do some more research.

Bah. Some people have no sense of humour. I just wanted to get the mastercard priceless into the post dammit. I'm an LPG fan, hell my 7 series is moving over to LPG as soon as I get around to it!

Is that 79.5ppl? The thing is bio diesel is food product, if 1% of car owners decide to convert to biodiesel we would be using oil that is destine for human usage plus we would have to increase rapeseed planting which would mean using land that should be use for growing food which mean we rely on importation of basic food or importing more virgin rapeseed oil from europe and they would be using land that should be use for food planting, I went to a seminar once where the countrys leading bio producers were and they were saying the government figures cant be achieved. lpg is a biproduct of oil distilation so would have been burnt off or wasted. we are been ripped off paying 40+ ppl for lpg because the garages make more selling lpg than petrol, I think they get about 20ppl on lpg but they charge what the customer will pay and since its 1/2 price +20% we dont mind paying that

The viscosity or is it lubricating properties breaks down after a while, cant remember how long, A chap who converted his daimler did analyse the oil before changing it, he said each oil change was nearly £100 so he wait till the oil really need changing. He was on one of those lpg forum.

LPG no longer needed as a company car has now been provided to me so now im going down the more power route...
NOS is the front runner and ive been told i can safely goto 450bhp with out having to do any upgrade work tot hte existing brake/engine and gearbox, this will cost me around £900 fitted with an electronic regulator ... Views on this people?

 

[jaymanek]

i personally think your playing with fire... its an engine that is tuned close to its limits already...

anyway im sure more qualified members will be able to guide you better..
