Is it possible to LPG an Arnage? I really like Bentley. Has anyone done this?

Anything else to look out for in buying one of these - 1998 model.

Thanks.

I don't know - but I know that many Range Rovers based on the same engine have been LPGed.

I have the 4.4 engine in a Range Rover with a Prins LPG system in & an 80 litre tank in place of the spare wheel. It was fitted about 7 years ago when the car had done about 30k it's now done 130k and never missed a beat.

It equates to about 30mpg on steady trips 35 if I drive like a nun compared to 16-18 on petrol. I don't notice any difference in economy or power on gas. I think because it's such a big engine and big car it's hard to notice any differences.

One thing that has changed is the price of gas, it was about 35p a litre when the conversion was done and it's now about 75p! Going 300 miles for £25 in a Range Rover did used to give you a very smug feeling! Now it's more like £60.

The conversion (and servicing) was done by Hilton Autogas in Cannock, they've also done my father-in-laws super charged Range Rover which is the jag engine which requires a different system with additional lubrication but no problems on that front either at about 70k.

I have done loads of work on LPG'd vehicles of all types, including a few of these engines in L322 Range Rovers. It's a great idea and really good IF FITTED PROPERLY. I would suggest that 95% of all the conversions that I've seen are on the borderline between dangerous and poorly-fitted.

The whole industry is founded on cost, so fitting the kit usually cuts as many corners as possible. If, however, you can find a company willing to fit it properly, AND give you a dyno cert before and after, proving that you've only lost 10% power or so, then you could be in business.

My pal has an L322 on LPG which I'd say is about 25% down on power and raises the MIL light after a couple of hours running. This seems about average.

Amongst the horrors that I've seen are an LPG ECU secured inside the wheel-arch with nothing more than No-more-nails and open to the elements.

I'd write you some "minimum standards" for the fitting if you care to go ahead

Some good points..........I have owned probably 15 lpg vehicles over the years, out of those I would say only 4 were 100% "right"...they seemed to run ok on petrol but not gas and visa versa.

thanks - it was actually quite difficult to get that right. I was, after all, savaging almost an entire industry.

But, I think I got the level right - ask me down the pub and I would have been a fair bit more "robust"
