yes. already serviced. my 30 litre travel only 210-230km. full tank roughly 410-430km. Or maybe i too heavy? i also observed that the rpm need to hit quite high (ard 3k) in order to change gear. Is it advisable to bore a bigger hole at gear box? (To reduce rpm for gear changing) Thinking of changing the stock rims from 16" to light weight 15" (but worry about my body kit get hit at hump) What about changing to light weigh crank pulley? Which is more recommendable? All these cost money.

Try those fuel injector cleaners from workshops/acc stores.. My take is that, u dun drag the car often and cause the injectors to be clogged.. I might be wrong.. And "bore a biiger hole"?? I dun get this phrase..

actually i dunno i drag or not. cause its auto. so... it should change the gear once the rpm reach right?

Hmm.... Engine ok. Spark plugs can use for another 10000km. Air filter ok. Engine oil filter, I assume it is changed. Now, check tyre pressures and in the morning, see if there is any leak at the bottom of the car be4 u start to drive off. Jus some simple checks to save some $$$ be4 gg to workshop and kenna chop again. Hehe!
