1. as yet there r no known instances of lpg adulteration
2. also quantum diff due to temp variation is negligible .. hence inconsequential for th present problem
3. it is assumed that th condition of th car and th driving conditions r similar and there is no leakage ............any of these factors cud result in mileage drop
4. it is assumed that th car does not run th a/c with th engine on ... when parked .... chauffeurs idling away .. housewives while out shopping ..... youngsters when with their girlfriend/boyfriend .... businessmen holding meetings inside th parked car ........ r usually th culprits
5. if not ... then th usual caliberation problem ........ most rampant acrosss th country
................ th possible solutions .........
a. never buy less than full tank............... if th pump fills more than th licenced capacity ... u kno his meter is faulty. ......in less than full tank it is impossible to detect short measures
b. at most pumps ... only 1 dispenser is caliberated correctly (out of th 2 or 4 or more for any fuel) and this correct dispenser is mostly shown out of order or is used only for th more fussy clients like taxis n autos .... idntify this dispenser and insist on filling from that only
c. if nuthing works ....... change th pump .... in th long run it is cheaper to buy th correct measure from a pump slightly away
