have recently purchased a previously converted Jaguar X300 3.2. It is
fitted with a Romano Single Point system, has been converted about 20
months and covered roughly 80k in that time. This is my first LPG
purchase and I am aware now that this is probably NOT the best system
for this car. 
I am very happy with the way the car runs, it's smooth and very happy
on gas. 
It is the gas consumption am not happy with. On a run the computer
indicates, if it was using petrol, it is averaging an expected 27mpg.
It is however only doing a factual 17-18mpg on gas. In normal use on
gas it is returning 14-15mpg. 
Most of the stuff I 've read indicates a fuel increase of 10% on gas. 
Is the gas consumption I am getting to be expected, or should it be
better than this? 
Best regards 
Mervyn
