LPG - 'Purists' need not apply!

I own a 72 V8 with less than 38,000 on the clock. I use it as my daily driver and love it to bits.

However, 18mpg is not my ideal.

I am looking to convert the car to LPG but have found that either the firms in my area are cowboys, or they dont want to do it due to backfiring problems they have encountered when working on Range Rovers. (Albeit they believe that this is due to the electronics fitted to those engines).

Has anyone had a P6 converted and/or does anyone know of a good firm in the North West area who are reasonable in price and more importantly, trustworthy? I live in Wigan.

Thanks, John.
 
Well. I am shocked.

I assumed that at least someone would have replied - even with a NO DONT DO IT or whatever for that reason.

Anyway, I have now found a reputable firm whilst trawling through the internet. Booked it in for next Monday at a cost of £900.

Fingers crossed. ???
 
Johnny,
You must be shocked very easily! I expect all our readers, being petrolheads, were lost for words at the very mention of LPG, however it was covered in my article on fuels for Rover P6s which appeared in the April edition of P6 NEWS this year.
I look forward to hearing about the conversion and the effect on your pocket in the long term. Good luck.
Regards, John.

I have also been thinking about an LPG conversion.
How did you get on?
Any problems.
Is fuel consumption the same?
What sort of tank was fitted? I was thinking that a round one would fit into the spare wheel well on the floor of the boot....
Also whether it would be possible to fit a 2nd filler cap on the offside for the gas filling point?

Whatsystem was fitted - I have heard of Typhoon system being OK for P6?

:p
 
I fitted an LPG system to a Jeep Cherokee 4 litre and was very happy with it. Make sure you get a system fitted by a member of the trade association (LPGA?), the only ones accredited under the government Powershift scheme. Which?magazine found lots of problems with LPG system installers but none with the govt approved ones. Your insurance company may only cover you if fitted professionally though DIY kits are available so presumably someone must cover them. I noticed no difference in performance but the equivalent of 40 mpg was very welcome!
 
BRC Bristol was fitted to mine. Check their website or search under BRC gas. I have posted the link at the end.

I have been to many garages and all sell different makes. All seemed about the same price bar one company who quoted double everyone else and each company prefer their own brand. You could go round in circles with this one!

Long term I couldn’t say how much I will save but the firm that fitted mine said that through experience, unless the car was as brand new, P6 V8's would do nearer to 14mpg around town on petrol. With gas, probably 10mpg. However, at 29p/litre, I can afford the difference.

I have had a 70 litre tank fitted, the larger type which sits sideways, basically behind the rear seat. This means I needn’t be at the petrol station every five minutes, and I still have some space in front for a little amount of storage. A flat donut type tank is OK, but it holds less and because the wheel well is on a slope, it would protrude quite a bit near the boot catch.

I didn’t actually specify where to put the filler although I did not want it near the petrol filler. The firm has fitted separate filler which bolts to the boot floor and protrudes where the tow bar would be. You can hardly see it. It's really neat and hasn't touched the bodywork.

I have also had a flash lube kit fitted which lubes the valves. This means that if I did want to run it on unleaded - I could. Mine now starts and runs permanently on gas but can run on petrol at the flick of a switch. It is more of a reserve than anything.

The car now runs smoother and quieter, starts without the aid of choke, seems to be much more responsive and the V8 burble is unbelievable!!!!

To those who are 'petrolheads' - fine. But this is my daily driver. Without the conversion (although I had to fund it), running the P6 would have proved too expensive. So, in essence, it has saved my car and kept another on the road. The P6 was built in the days where petrol was affordable but not any more.

I am glad I have done it and would advise anyone else to do the same. All I would say is, shop around and speak to a few different firms before deciding. I paid £950 in the end and although the cheapest, it wasn’t just the price that swayed me. Some firms were very uninspiring to say the least.

Good luck!
:D

Johnny,
Thanks for the details which will be of some help to others, I'm sure and can only disagree with two minor points - Petrol has never been affordable, it has always been a luxury (when it was very much cheaper salaries where very much smaller!) and the worst consumption I ever got in an auto V8 (by driving "enthusiastically") was 13 mpg - 20 mpg around town and 26 on a long run so I would not consider 14 mpg to be average. Good luck, and please advise on long term usage.
Regards, John.
 
Without sounding rude, this is the trouble with some classic car enthusiasts. This is a discussion forum, not a precise technical database.

Sorry, YOUR comment on the price of petrol is YOUR opinion. It's taxed to high heaven, thats why we had bedlam a few years ago during the fuel crisis. It's never been so bad and it's going worse. John Prescott and his Jags? You never heard Maggie being critisised for driving her Jag or P6 did you?

Secondly, if I'm out one or two miles per gallon - SO WHAT? Then again, what are you basing your average on? I'm still saving a fortune. 14, 15, 16mpg. At three quid+ a gallon, it does'nt make much difference really.

Iv'e spent nearly a grand on a conversion and have posted the item on here to help others. If anyone has looked into this subject closely - it's me. Picking fault at sod all does'nt help. If I sound off hand - It's probably because you've made my blood boil. Someone out there always has to have the last word!

Splitting hairs. - PLEASE! :angry:
 
You do sound rude. (And I wasn't being.)
It's a statistical fact that fuel costs compared to wages are about the same as when some of us started our motoring in the sixties.
I only quoted exact figures because you quoted exact, and in my opinion, incorrect exact figures
If you are not prepared to discuss in a reasonable manner go and boil your blood elsewhere.
And this in my last word.
 
Last word on the matter? You had nothing to add in the first place!

STATISTICAL FACTS (As you call them).

It is also a 'statistical fact' that in the sixties and seventies, the nation as a whole didn’t bring the country to a halt over the price of fuel and didn’t criticise the government for running gas guzzlers.

It is a 'statistical fact' that propane conversions in the seventies and eighties didn’t catch on. Have you ever thought why LPG is so popular these days? (And before you say it's because of the governments promise to cap it, no; gas has always been cheaper than petrol) – now there is a fact.

Exact figures. What? The figures I quoted were what the fitter believed to be nearer the mark. I quote…..

“Long term I couldn’t say how much I will save but the firm that fitted mine said that through experience, unless the car was as brand new, P6 V8's would do nearer to 14mpg around town on petrol. With gas, probably 10mpg”.

The figures YOU quoted were the mpg return YOU got on YOUR car. I quote……

“and the worst consumption I ever got in an auto V8 (by driving "enthusiastically") was 13 mpg - 20 mpg around town and 26 on a long run”.

I’d hardly call either ‘statistical’.

Never in a million years could you get 20mpg out of a V8 P6 around town - Never.

So, before you decide to become the leading expert on LPG, drive one, convert one, whatever, but don’t pick fault out of something you clearly know very little about.

Rude - no. If you read through my posts on the forum you will see that I am far from rude. Due to my points on not only LPG but the Nigerian fraud etc, it's more likely that I am much closer to reality at the moment and more likely to be able to help people. Don’t try to tell people about conversions and become involved in this discussion when you clearly have no knowledge in this area.

The fact is that your 'petty picking' isn’t needed and just isn’t constructive. What does it matter if your car did more or less mpg's than others? What does it matter if you believe petrol has always been expensive and I don’t? So what? I'm keeping a classic on the road at a price that I (and many others) can afford. By expressing my satisfaction in doing such a thing, I might just persuade others to use their cars instead of leaving them to rust somewhere and never be driven again.

I am annoyed at the fact that you are the one to pick fault. You will probably never convert to gas. You notice that p6jpe and rovermorris999 had constructive comments to make. They have genuine interest. That is what the forum is about. Not belittling one another.

If you are so wet behind the ears to think that people would not rise to such comments then you are sadly mistaken. It is unrealistic attitudes such as yours that puts new people off running classics. Don’t be so petty. This is the 21st century -'Come on in'!

Should any genuine LPG converter care to discuss the matter or needs any help, please feel free to email me at sibley@blueyonder.co.uk. I'm no expert, but I do own and drive a conversion.

Thank you, John Clee.
 
hi,
yes in a million years as you put it, i have driven numerous V8's and one i had did 20 to the gallon around town and 27 on long runs. i have also had cars that have done 13/14/15 around town and 20 tops on long runs, they are all differnt, i have been driving them for 9 years, so let's not fall out on what they can and can not do to the gallon.

:0
 
Ian.

I agree! The idea was to merely help persuade people that were'nt altogether convinced about the idea.

Hopefully this will not put them off.

Filled the car up today. In the last fortnight, I have driven 180 miles on only 15 quid!!!!!

Well worth it I'd say!!

:D :) ;)
