Lpg

Does anybody have any general experience on running a Range Rover on gas? I'm looking to either buy one converted or buy one and get it converted myself but I'd be interested any do's don't's and general advice, is it worthwhile etc.?

Classic, P38 or L322?

Hopefully L322 but it's a bit budget dependant..............

Early L322 with the BMW engine are OK on gas, later ones with the Jag/Ford AJ lump are no good on gas. No personal experience, just what is reported on here. Diesel is better IMO.

Thanks for your comments, much appreciated.

My BMW M62TUB44 Powered L322 is great on LPG using a system by BRC and a tank by Tasso.

Returns 15.1mpg @ 22p per mile on average...

Make sure the install is carried out by a registered LPGA installer and get a certificate of installation as some/most insurers will require this.

Most system are sequential multipoint units which is essential for smooth running.

Mine has a Flashlube system fitted to keep the Valve seats cooled and lubed as seat regression can occur on some engines (the BMW converts well and some report a Flashlube system is not required - but some fit it as a precaution in anycase)

The Jag AJV8 engines don't convert well due to softer valve seats, so avoid these.

I had a Classic also on Gas with a Lovato system which ran well.

My 735i with the M62TUB35 Engine is LPG converted with a OMVL Dream XXI-N system and this seems to work well on gas too....although Iam still learning the control proces of the OMVL as it doesn't seem to have a set point of transfer to Gas and some days it switches over within a minute an others days it can be 10 minutes...whereas the L322 BRC system switches the moment the Coolant temps gets to 60degC and the engine is decelerating!

Appreciate your comments. Thanks.

Late P38 vogue with mulipoint lpg is a good safe bet I'd say

+1
But always budget for repairs with any RR.
My LPG has never missed a beat in 80k miles on my '02 P38

Dangerous talk

Thanks everyone for your comments and advice. Much appreciated.

I've got a Zavolii sequential LPG system on my 01 Vogue (P38 ). Was on there when I bought it, been running OK for a couple of years.. I need to do the filter, and thinking of fitting a bigger vaporiser, but even as it is as the moment there isn't a noticeable reduction in power over running on petrol. My only main niggle is the float valve in the BRC tank doesn't go below half way, so I don't know when it's going to run out. Apparently the Rover V8s don't seem to have the valve recession problems, but a top end refresh/cam change is on the list for this year, so will get a first hand look at what the valves are like when I do that.

My p38 gems is currently in the garage with 8 burnt valves from lpg - big job

A mate has an early L322 on gas had it converted at Autogas 2000 in Thirsk, North Yorkshire. First class job and had it reclassified for lower tax bracket.

I have had my 2004 L322 V8 on a STAG LPG system for the last 4 years. Not had a problem ever. It does need to be serviced every 200 hours (£50) though.

It was done by Professautogas just north of Cardiff, so just up the M5/M4 for you. They are really excellent in terms of customer support and professionalism in servicing, installation. They do Porsches etc as well!

Ps @Bazz, it is only £10 off for registering as LPG and you don't get free access to the London congestion charge either any more!

my 4.4 vogue l322 was fitted with lpg in jan 2006, cost was £2300 & showing 50,000 miles. its now on 103,000 still going strong with no issues

The original owner of my 4.4 L322 has an LPG system installed but removed it because he wanted to use the spare wheel again .( Y)
So I am having the system re-installed. I had LPG on my S-type Jaguar and that was excellent, so I am going to do the same to Renee the Range Rover.
I'm going green (in so much as you can with a 4.4 V8)

Would rather have the spare wheel

I've had to Disco's on LPG one 3.5 ended with 270k and a 3.9 with 90k had no problems only mod I made was fitting a relay on the fuel pump as the emulators only shut the injectors down and ran the fuel pump dry my fault. The only thing you got was a very small gap between LPG & petrol hardly noticeable.

Hi just seen your post on lpg and have never really seen the green credentials of it, it's a bit like electric cars when you factor in the batteries and motors. Most people with lpg have good financial reasoning to support it so if that doesn't fit with your intended driving it may be greener to leave well alone, we have enough to deal with as the engines come from the factory so I'm satisfied to pay the pump price for peace of mind and drive my Range like a chauffeur, most of the time anyway. After all it is fitted with a "Dad's Taxi" badge, lol.
Tricky.
