I purchased a Honda City 2007 Vario couple of months back. The car's engine gives a knocking sound whenever the car is accelerated. its a constant sound.
I got it checked from Honda service center and they said that this Vario model has an inherent problem as the petrol quality is poor, he advised me to use hi-octane instead.
Can u guys guide me expecially those who own a similar model???
Thanx in advance.
