yup its just stupid claim, it isnt true at all
i got same avg on my first two refills, there's nothing left at all in the cylinder, i know that because i got kit n cylinder both serviced, nothing came out really
lpg kit n cylinder is a good idea but only if prices stay in control in winters otherwise lpg simply cant b used in winters, it already came upto as high as 170 lets see where it goes now when winter really starts
