greetings, took over a kancil old model. My dad barely service the car, accept if go for long distance driving / juz top up when low level. i found out there is vibration when i cold start the engine, the oil is kind of black-ish when i checked. it's 3/10 above the lower level limit... I am thinking what brand / details of engine oil i should change? ) Can a old car like mine change FS engine oil? And oil filter juz use perodua one ok rite?

Secondly, about the spark plug, can i change new set? wat spark plug are good? Denso Iridium Power Plugs? NGK? heard tat Kancil uses either EZ660 IW16 and EZ850 IW20.

third thing is, the timing belt, i think my dad didnt changed it for quite a long time, Original Daihatsu Timing Belt Kit Set Kancil 660cc okay or not?

Thank you for the help, sorry for noob question... i have been doing research abt them, but juz wan a quick idea from all the sifus. once again, thank you. 

Hello every1 sorry to bump in.. What doyou guys think ? Should i get the perodua oem air filter or should i go with k& n air filter as i heard a lots of rumours stating that the k&n air filter filtration is not as good as the oem 1 ?
