Maybach ,
i just topped up on fuel this morning - 547 kms on the trip meter and i pumped in 42 litres of fuel - that comes to an FE of 13.02 KMPL .
i have a free flow and a K&N air filter ..and i drive sensibly these days
not revving above 2500 RPM and 80 -100 KMPH !!
the least i have got with pedal to metal driving and getting stuck in the city traffic is 10.8 KMPL
so dont go with all u hear !
cheers
