One more thing, you got pump air for your tyres regularly....I realised that it really helps...I do it about once a month...think should be enough...
normally 250 front 230 back... sometimes.. feel very fat.. driver.. pump 270 in front 250 back... already super high liaoz lol ...
I stick to original 230 front 210 back... this month Fuel Consumption is between 12.82-15.75km/L
