my petrol tank is at 1/4 ....... i only drive within metro manila .... no hills for me ...... had a change oil and new spark plugs as well as bnew air filter a day before the LPG installation. I always drive alone and feel the weight of the tank has not much to do with the FC.

as of now the pressure guage at the tank indicates about 1& 1/2 line (1 LED lit)..... 6 lines i think is full ....... i'm only up to 190kms ...... still can't guesstimate but not optimistic at this point .... is there a calibration necessary ? i think i'll consume the rest of my LPG left in the tank in a day or two.
