hi guys, im new to the club, i own a honda jazz E for around 1 week +

guys, im using shell vpower(ron97) petrol, my 1st tank only allowed me to go around 400km only.. and the display is showing around 10~12km/L

i was like OMG, the fuel consumption is very horrible, as i read the review can actually go until 17km/L

i just wanna know is this because the engine is still new? or is my car having some problem, a heavy "MINYAK EATER" or i need to do the 1st service and monitor the fuel again??

need help, sifu.. =(

yea city drive, but i only drive at night, not really much car
maybe engine is not heat up yet, i will monitor after 1st 1000km service.. thanks for advise
