hi there,

mine has been dropping drastically for the past 1 yr ... i've been doing purely city driving. from like 12km/l drop to now only abt 9km/l. been servicing my car every 5k also. the last service somemore use fully synthetic also no use. the only reason i could think of is that my k&n filter haven't been cleaned for quite some time, but will that cause such a drastic drop in fuel consumption? planning to get a normal air filter to test.

hi guys, i think my tyres have wore out quite badly.
recently i can hear a very loud whishing sound (not sure how to describe it) from my front tyres. its like every cycle it spins, the tyre generates like whishing sound. so the faster i drive the frequency of the noise increases. and when i slow down the frequency decreases in parallel.
its very obvious especially in the morning and also at night. and the noise gets even louder when i swerve to the car to the right. but in the afternoon the sound is less notable.

my car abt 3.5 yrs liao loh.
tyre same as stock one but i already changed it abt 1yr plus ago.
no other modifications.

sigh ... my city 3yr plus liao and my petrol consumption keep droping like crazy. dunno for what reason. now per full tank pure city driving only can give me abt 300km. thats like wira quality nia. using k&n, nvr service outside from honda before. i get a feeling its got someting to do with my gearbox .. its so sluggish
