LPG converstion

Im considering getting my car converted to run on LPG. I would like to know if it's really worth it. I understand its going to cost about 1500 to have done, which in theory means I should start saving in the second year. I have a Ford Focus 1.6 16v petrol, and do about 15000 miles a year. Am I going to notice a significant drop in power/performance?

Is it possible/costly on a new RR or V8 Disco?

I had a LPG 1.8 Mondeo.. Admittedly it was a Ford conversion, and had to be replaced 3 times in the one year I had the vehicle for..

LPG seems to be creeping up in price, the local garages here are close to the 50p a litre mark. When mine worked, I was getting approximately 22 to the gallon.. (Motorway miles at slightly, above the speed limit..) I didn't notice any difference in the cars perfomance.. Whatever figures the conversion people reckon you will get, don't believe them, I reckon you would be lucky to get 25 to the gallon. If your planning on keeping the car for the next 5 years, then it will probably be worth it. But you will find it a pita, keeping the car topped up with LPG isn't always convenient.. IMO, your going to be better off adding that 1500 to the trade in value of the Focus, and buying a diesel..

The Focus is pretty economical anyway but obviously with the stupid amount of tax on fuel it could be worthwhile. Usually people do the conversion on real guzzlers like the Range Rover or similar with 4L and above engines.

One problem you have is lack of bootspace - the other is getting the LPG - prices vary quite a bit - check first if there is a cheap supplier in your area - you can get it for as low as 35p per litre but 40p is more common in Swansea.

You lose very little power - most people don't notice as long as you get a good conversion. If your car does say 35mpg normally it will prob do about 28 - 30 on lpg.

Hello Tim,

1500 sounds high to me for a single tank system I'd be looking in the 750 - 1000 band including labour. You may be able to save more if you buy the parts and fit it yourself, there are lots of companies who sell good kits with good manuals. Dont get too hung up on the inspection front for insurance purposes most of it is cobblers and you can have it inspected to fullfil this requirement.

Directline do not inspect my gas barecue or my Sungaz grill everytime I go camping. Correctly fitted it is inherantly safer than petrol.

Talking of gas it amazes me why hydrogen powered cars aren't in use. I am NOT talking about hybrid vehicles or fuel cells - just using hyrdogen in a similar way to LPG in a normal engine. Internal combustion engines have had over 100 years of development. They are well proven and are much better than these expensive hybrid electric things.

Hydrogen is no more dangerous than LPG and would use similar types of tanks. BMW and several other makers have systems available - BP was ready to start selling hydrogen through it's filling stations. Of course with hydrogen there would be no CO2 so you could drive your 4x4 and be greener than anyone.

I always wondered why they wouldn't go down the hydrogen internal combustion engine route.....

For some strange reason the government has put a stop to this - they want car makers to focus on hybrid or electric vehicles - it seems the the thought of still being able to run around in a 4x4 AND be green terrifies them!!!

Hi

How old is the Focus/Mileage, personally I'd agree with Tony and say put the 1500 towards getting a Diesel.

I used to have a Landcrusier Amazon 5.7V8, yes I know bit of a different beast to that of a Focus, but the Gas conversion was a pain in the arse, used far more gas than the normal petrol fuel economy plus if you put your foot down hard ie overtaking it could not physically pump enough gas in to the engine and switched back to petrol automatically, then had to stop, turn off the car, reset switch to gas, re-start engine and carry on. Plus Gas is getting more expensive to buy now.

Don't you mean 4.7? Totally agree get a diesel Focus - the TDCi is great to drive and very quick. I averaged 44mpg in one - other diesels(VW or PUG) tend to give you about 48mpg.

My organisation does OE conversions for Vauxhalls & Saabs (sorry - can't get you a cut price deal for a Ford!). Points made thus far are mainly correct;

- Little noticeable effect on performance under normal driving conditions
- Slightly lower fuel consumption than with petrol, more than offset by lower fuel price
- Readily available in most parts of the country
- Loss of boot space unless system fits into spare wheel well which is not replaced like-for-like (eg space saver or aerosol sealant/inflation)

May not be a big issue for you but you cannot use the channel tunnel with a LPG vehicle, but your ARE exempt from the London Congestion Charge!

If you want more technical info PM me and I'll see what our Alt Fuel guys have (note I'm away for next week).

Andy
