This is just my opinion and yes you did ask for it.
The only way a Range Rover on gas would be cheaper to run than a Laser would be if the gas the Rangie was running on was fresh air. You have to take into consideration, insurance, maintenance, lubricants for the gas system, cost of tyres, rego costs. etc....
It would be cheaper to put the Laser on gas.
I reckon you would be right Pedro. Its been a good car but i wouldnt fair to well in an accident.Quote:

What compression is the motor running
Manual or auto
The main reason for poor running on gas is either cheap poor systems, poor tunning or low compression motors (usually last 2)
If it is a high compression motor, tunned for gas, you should get 80% or better L/100kms of petrol, ie 10l/100kms petrol would take 12 l/100km on gas, or 20 goes to 24 etc
I have spoken to people that have put top quality "direct gas injection" in post 2000 P38as and are getting same kms on gas as petrol and have not noticed any performance decrease. The big negative is that it is a cost of towards $6,000 to do.
Hi, the car is a manual, is running dual fuel and is EFI, not sure on ignition method, did 87 rangies have an ECU? or were they electronic igntion, i cant see them being points.Quote:

I will be getting it tuned if i get it, replace plugs, leads, service everything etc. I will get the timing checked and make sure all is good.

Unless it's a direct injection method similar to what Wal described, where as the gas system is independant to the petrol system (injection wise) running seperate injectors and ECU mapping for gas and petrol.
Tuning duel fuel cars is a black art in itself. one fuel needs the gas to be retarded the other advanced. Usually duel fuel cars are running on a happy medium as to maintain trouble free switching of fuels, thus effecting the fuel economy on both the petrol and gas.
The way I see it, a good system will cost a high price and take years to repay itself, a cheap system is just a false economy.
Well going by the figures he gave me for km/tank (given they are even remotely close to being true) it sounds as though it has been tuned for gas. But given you only give it a run on fuel every now and then it doesnt really if the tuning favours gas.

I'm not trying to be mean, I have been there and gone through this before. Except I had one advantage, carbie cars are a lot easier and cheaper to tune at home, you loose a lot of acceleration on gas, in theory it should be great offroad due to the fuel equalisation.
well it starts and runs so thats somethingQuote:
