ok no problem for chat
yes 95 is less but may be because of crowdy road,
i think lesser gas supply make it khata reri on 1st gear,
it is common mistake by mechanics,dont worry
try to get in original flow
then
because if 1 time it gives u 95 then it doesnot mean that average decresaes,always check average by 3-4 readings
for exapmle 1 trip u find 95 km
2nd time refill full cylinder & check may be lets say 100
3rd time refill giv 110 km
then this means that it is not less average 95, there r many factors as
crowdy road, ,weight in car, pressure of cng may be less at station from where u took cng etc.
