would somebody stop talking about average please? and lets focus on the car now. top up your car completely, get your air filters, oil filter, engine oil, brake oil, cvt oil changed. the left meter is going to show 540 something kms, dont trust on that, and the average meter which tells how much km/ltr, sometimes it show 20 and sometimes it shows 26 but sometimes when the car is stopped it gets low as 12km
always rely on the kms divided by ltrs procedure. and please stop worrying about such stuff as long as the car is good with you.
