There is another thread here about LPG but not much detail. I looked into this myself recently, I thought that maybe getting rid of the TD6 and it's 104 litre diesel fill ups at the extortionate rates could be lessened. I had a real whizzy idea of getting a 2nd hand Supercharged Range Rover with one year's warranty, low miles for about £30k, then spending the money on an LPG conversion and having the best car ever for little fuel expense.

I did lots of research and here are the facts before you jump into it. These are Base 101 and onwards...

LPG conversions can only be done on petrol engine cars (of course!)
Conversions costs vary from about £1700 for a small family car upwards
JE Engineering will do it for £3K for a normal 4.4 petrol, or £3500 + VAT for a Supercharged FFRR, RRS SC or D3.
The Supercharged engine, the Sport and the Disco conversions have been problematic and have engine fault light issues - JE are suspending conversions until this is fixed
You'd need to spend a large amount on Petrol or diesel to recoup the costs ( I do a minimum of 20K a year and would still need to achieve 16 mpg from a FFRRSC to pay it back within 2 years!)
Doing 20,000 miles a year yould save £1600 on fuel as compared to diesel if you manage 16mpg.
There is a minor reduction in your Tax disc for getting it done (£10-20!)
Your insurance WILL increase marginally
Any Land Rover warranty on the car is completely and TOTALLY voided. Even if the stereo breaks, you cannot claim on warranty, they will not touch your car.
You will also have to take your car elsewhere for servicing for the same reason
Your MPG will decrease on LPG by about 2-3 miles and the performace is marginally affected also
The LPG tanks although stated as 95 litres can actually only get about 85-88 litres filled and sit in the spare wheel well
You keep the standard fuel tank so you effectively have nearly 200 litres of fuel on board
The engine always starts on petrol then switches to LPG automatically
A small interior switch tells you the amount of LPG left
The conversion takes about 5 days and typically comes with a 2 year warranty

You can get 4.4 petrol lpg converstion done by alternative fuel in barking essex with 5 year, 60,000 miles warrenty ,best prinz system installed for only 1850 pounds, had it fitted last week and works like dream!

Do they warranty the whole car, replacing the lost LR warranty? If not, then the above still applies
