I know people have provided some email about this issue in 2005; but I am only just thinking of having this done and wonder if someone can tell me the value in having a 1997 Falcon EL convered to LPG - is it worth it?

I keep hearing about Sprint Gas, OMVL, IMPCO and others and have no idea which is best - are they all unique or when you buy a conversion kit do they have different components from different companies?

What is the current recommendation from people in the know as to what to go for?

Thanks for your help.

If you want to help reduce greenhouse and the daily pump price then yes.

In terms of keeping money in your pocket when you take into accout the cost of the system and installation along with reduced power (20%-25%) and increased consumption, then NO.

I was lucky enough to buy a vehicle with the LPG system already installed so for me yes it was worth it.

20-25% reduction would be doubtful IMO. I really don't notice the diff at all in my Patrol, but i do hear people say you lose power. Yes you use more than you do with petrol. I guess it would at worse half your fuel bill. So do your sums on kms travelled in a year, expected savings, how long you expect to keep the car and go from there. As for the brands, I can't fault my Impco. Like Rod i was lucky enough to get mine with the gas, maybe you could hunt for a second hand unit to make it cheaper?

I got Tartarini Injected Gas System, and 5% would be the max power loss.....
You can't really tell the diffrence if it using petrol or LPG without looking at the
petrol/lpg switch....

we've had gas on our commodores for a total of 15 years now and never have we regretted it. we notice no lack of power certainly NOT 25%.we have had our 91 commodore dino tuned and on the dino there was no different between gas and petrol still over 100 h/p, that was with the impco set up. we have had impco, lavarta systems and we now have the mega gas unit (due to the all mighty dollar). the best one by quite a way was the impco, the mega gas is the Australian unit and has a 3 year round Australia warrenty and was around $1,000 cheaper to convert than the impco.
one thing to remember is to run oil injection as this is what we think has helped our cars last so long, the 91 commodore has now done over 700,000klms and never had any motor work done on it except oil changes ect and oil treatment.
good luck hope this helps.

All right I'll be corrected to a certain degree. I worked the 20%-25% on the basis that I get 5.6ks per litre on petrol and 4.6ks per litre on gas thus being 20%-25% difference.

Mate has Impco systems in both his EF and EL falcoons and recons it's the only way to go. Dunno about the 20% power loss. He says theres minimal diff between running between patrol and gas.

I had an EL converted in 1997 and it was a disaster by a specialist converter in St Marys NSW. It werked fine for the the first twelve month under warranty and then the trouble started, rough running and going constantly out of tune on petrol or gas, had to get the b---- thing serviced every six to 8 weeks. So much so that in 2002 I bought a 100% gas Falcon (fantastic), the only problem with that is that you cannot do the big trip around Aussie because some of the LPG outlets are 600 km apart and the tank holds max 600 km.

My thoughts.
Bought a van and immediately converted to lpg - did impco, version designed for the van.
Upfront $2000 - Now I giggle everytime I fill up... $25 compared with $80.
8 months ago $20 compared to $50. No matter what they say about gas increasing, so does petrol!
Yes, it will take a while to recoupe my expense, but gee it's economical.
After breakeven - constant savings.
Power loss, negligible!
My suggestion - just do it! You won't regret it.
