Hello All.

I am looking for some sound advice regarding LPG conversions.
I've made an impulse buy and bought a Jag XJ made in the late 90's era, 4L supercharged.
The car has had a full service history upto its current mileage including full MOT's.
Do I know a lot about Jags and their reliability? No.
Now you know the type of person youre dealing with, not a lot of money or sense biggrin

So the car has 110,000 mileage on the clock.
I've made plenty of phonecalls and I know which kit to convert to and prices are near the £2,500 mark from reputable places that have a history of converting Jags.

Question is, do I convert a car with mileage this high? Is this considered high mileage for a car that's 17 years old?

Bought the car for 3k....
I plan on loving it long time....

go for it then, i'd say.

you'll obviously never get your money back, but i guess thats not the issue.

I've got an LPG Nissan Pathfinder 4.0 (2005) - it was converted in 2008 at about 40k and the then owner put about 50k on in the next 2.5 years-

coming up 3 years we've had it now and its getting to 120k miles

I didn't do the conversion - but its run pretty flawlessly for the time - tune up every year- ish ((which is about £100 or so)

I did a fair bit of research about running LPG in high mileage engines - as long as you have a decent flashlube kit the supposed 'value seat recession' shouldn't be an issue...

I would say it depends on how long you plan to keep the car and the sort of miles you are going to be doing.

I have a XKR 4.2 that I got converted with just under 60k on the clock, now at 95k. I estimated that the payback time was around 18-24months for me depending on the gas and petrol prices.

The XJ is an easier job than the XK due to more space under the bonnet. Quite a few places have experience with these. When done you should have no ecu lights and not be able to tell the difference between running on gas or petrol.

What system are planning on getting fitted. I found conversion prices varied enormously between 2-3k depending on the kit and number of vapourisers. In the end I went for a cheaper conversion with 1 vapouriser and the use of petrol additions when demanding more from the engine. This meant that under normal driving it isn't using petrol but does when you put your foot down. For me this seemed a reasonable compromise.

The mileage is low for the age; a look back through it's history would probably show mileage tapering off over the last 7 years as owner are unable to face the fuel bill.

Break even on the conversion will depend on mileage and driving style. It was 10 months on my WRX Impreza. Try this http://www.drivelpg.co.uk/about-autogas/savings-ca...

Jags started getting good in the late 90's. IIRC The XJ won Top Gear customer satisfaction awards when the new series started in 2002 and that was based on 3-5 year old cars.

Do it; while you won't make all of your money back, you'll delay the point at which the fine of lady depreciates to nothing.
