Work for most port fuel injector but won't work for direct injection , engine oil sometimes really depend driving habit , 120km 8 year old local car i service in time whichever come first

, i flush power steering fluid , coolant and brakes fluid every year , I only flush my atf fluid d3 every 40k replace filter every 80k , since fluid there are boiling point know the limitations then can last a bit long rather than waste time and money change atf fluid every 20k d3

Engine oil is like no matter how good you use is like once you fried a fish entire oil is black , I mean if u use fully synthetic not always travel far I rather you buy semi drain every 3k lagi better right .....

Using all this cleaning agent are nothing bad or good if your car in good condition In engine part unless you are type not bother when problem come only complain then give it a try if engine running fine when service remember let your engine hot enough only drain the oil

But personal I not prefer suction haha

Since you already show the picture and obviously you already can tell how many work has to be done lmao

This is why I'm saying not working for gasoline direct injection since the injection are straight to chamber and is not typical people can do it when needed remove so many things haha

Any fuel cleaning additives add into fuel tank only work for port injector

Which mean the fuel spray into intake vavle clean the intake vavle and all the unburned things will burn at combustion chamber

Malaysia I don't see yet maybe have or I don't know but there are other way to clean direct injection by blasting similar wood Ash more hassle

This is why there are newly technology multi port injector when running eco using port when performance needed direct injection

if you know what you doing like to DIY ok lah when come to typical people which really hard for them , sent to foreman i guess rm30 labor charge no one want to do it , rm100? 150? 200? meh i don't know is this service include intake manifold gasket ? or just a silicone sealant etc , some intake manifold with water passage if typical people no idea what they doing block the water way GG then ....

if typical people no idea what they doing better sent to foreman , my logic no matter sea foam blah other liquid chemical agent when cleaning intake valve still need a proper experience like have to close the valve only you start cleaning which have to turn the crank pulley until the valve closed 1234 or 1432 no way allowed the big whole chunk just drop inside combustion chamber

still need air gun blow the remaining or clean up out of the intake valve any remaining cleaning agent residue etc , a lot good product out there still need proper way to proceed like the picture you show not a easy task
