Title: Grey Motor- Gas Conversion?
Post by: 20.4_seconds on April 12, 2005, 07:28:26 AM
Hey Guys,
Just a quick couple of questions, with petrol predicted to reach the $1.50 mark sometime in the near future, what are the possibilities of converting the old cars on to gas?

Has anyone done it?

Is it possible? What was the outcome?

Nick

Yes it can be done, but it's questionable how worthwhile it is, as a general rule, for cars this age.

LPG conversion requires the same hardened valve seats as a ULP conversion, which is not cheap and given that there aren't any grey heads around under 40 years old, you'd need to be really confident that it was a good one you were having done.

As the cost of petrol rises, the inflection point at which it makes economic sense to do this conversion drops, but you're still talking about many thousands of litres of fuel to reach that point.  Do you intend doing those sorts of miles in your FE?  Bear in mind also that the price of LPG is not a constant either, and could also rise, wiping out your expected savings.

There's a worthwhile read on this topic from Money Magazine ($2).

cheers

Ta Ret,
Thank's for the info regarding the conversion, I have learned another valuable bit of knowledge about Grey Motors - A couple of people had asked me if I was going to put her on gas. That's all
Having previously owned a dual fuel 4x4 running an old 2F, I was also just curious, myself about whether it could be done to the old grey. I pretty much knew the cost involved and any benifit's to be gained. But
thank's for the link from MM.

just as i was reading this i htough id add my two cents

although petrol maybe 2-3 times more expensive than gas, gas does burn alot quicker which means by the tiem you go putting all the imco gas shit on the motor, and also trying to find or get made a kit it would be pointless

cheers
