No problem if you want to stuff the heads, valves and amy moving part.
LPG is ok in a low cost car, I have it on my Vectra however, all the above has gone on mine.
LPG does not have the normal lubricants and cleaning properties of normal fuel.
My advice, DO NOT DO IT.
Not sure when you had yours done but you can now get them with lub kits so the dry LPG doesn't damage the engine. You are also advised to run on petrol every so often.LPG is ok in a low cost car, I have it on my Vectra however, all the above has gone on mine.

Had my Range Rover with the BMW 4.4 engine done and it's now saving me bundles. Petrol - ave 16mpg £1.14, LPG - ave 14mpg 59p!
LPG storage for heating is in tanks which have the feed off the top - the heaters use the gas. LPG for car fuel is drawn from the bottom of the tank in liquid form - so a completely different storage tank is required.
You cant get around the fuel duty between the two types of tank - unless you have both tanks and a friendly tanker driver!
It is cheaper to buy in bulk although there is a rental charge for the tank so you need to use a lot to make it worthwhile.

I tried to get my 2004 Porsche Cayenne turbo converted to LPG at greenfuel company in Bath cos i am fed up of only getting 11mpg!!!! They said they done a few cayenne S and after 8 days they gave up stating not enough room under bonnet/wheel arches due to the 2 turbos/intercoolers!!
Porsche GB also advises not to convert stating the car is designed to run on Super unleded or unleaded only due to the massive performance!
I think its ok to convert other less performance cars but only time will tell if engine wear occures!
I guess if we want to buy cars with massive performance that 4 years ago were £77k but now only 20K we still have to pay through the nose for petrol/maintanence. The lesson is buying the car is the easy bit, running it is another matter!

LPG conversion on a Cayenne....anyone done it? Just wondering. Lotta car for 20K. Just needs cheaper fuel costs.
www.tassoautogas.co.ukGive the above guy's a call. They are in West London and run a converted Cayenne. They did my RR a several months ago and I am very happy. I was advised to run on petrol for a few miles after every tank of LPG. Conversion was under 2k which was well worth it.
If your worried about LPG not lubricating the internals you can get a lubricant injector which they will happily fit for you.
For me was a nobraininer, cheaper fuel, cheaper running costs, lower tax, free congestion charge,no noticable power difference.
All the best - Fulla.

What did you have to do to qualify for the free congestion charge? Is there some sort of official test/certification process?Ranger 6 said:

Be aware that one of the biggest practical differences between the Cayenne and the Range Rover is the amount of space available to fit the tank - usually in the spare wheel well. When you are told you are getting a 70 litre tank, what you are actually getting is around 55 litres of useable fuel. You will find that you will end up with a range on LPG of not much more than 150 miles. The Range Rover takes a 95 litre tank (about 75 litres useable) and has a range of around 260 miles. You don't need a bigger tank in a RR but if you want a bigger one in a Cayenne, you will lose part of your boot.

I have the spare wheel tank. It only takes 63-65 litres of LPG and I get about 230 on a motorway run and around 175ish around town.HARVARD said:

Did your mate get his Cayenne Turbo lpg and if so where when how much how many miles has he done and has he had any problems?Im still trying to do the same!
So has anyone succesfully managed to convert a Cayenne Turbo to LPG?.....
The tank issues could easily overcome if you are willing to sacrifice the boot space (ie 70 litre LPG tank cylinder in boot, will take up half the boot), but dont know about the logistics of the rest of the conversion...
Would definitely conisder getting one converted, as the turbos represent awesome value for money, and are a pretty awesome car too!

instal a big storage tank at home
not sure the taxman would approve of that.but
if your friendly with your local farmer chances are they have a mass of LPG used for heating in the chicken runs etc.
apparently they are really cheap and some already have the nozzle thingy, apparently
My brother has had his Cayenne Turbo converted to LPG, and has done about 20,000 miles since the conversion. Works fine, although the limiting factor to the output is the size of the injectors. He's in the process of having larger ones fitted to get the full power output when running on gas. If you want me to put you in touch, drop me a PM with your email address.
