Yes, then get spray and spray into intake.

Then whole car go do service flush all engine oil all out. Best is within 1-2 days after you pour into fuel tank. Make sure fuel tank almost empty then pour in and run it before refuel.

Basically whatever inside engine, injectors, fuel line, intake, exhaust all clean at once.

OK got it! Thank you for sharing really appreciate it

Is it suitable for my car if it currently already has some engine oil leaking issue? my engine has ran >400k km without any overhaul yet (camry 2008) and another car 250k mileage with slight engine oil leaking too. worried that clearing the gunk out will cause the engine leak to be even worse

Check where is the source of leak. If top then no problem.
Better send your car to change the seals.
Confirm will worsen the leak cuz your mileage is super high

When I park my car it usually drips some oil on the ground. Not sure which part is leaking though. What if I just add into the fuel tank instead of the engine? Will it be any more effective than not adding?

Adding fuel tank only cleans fuel line and valves
It's like cleaning 1/3 only

Parking. Thanks for the share.. all these while I only do the pour into petrol stuff. Not yet try spray and mix with EO

I just poured like half the white capped bottle into the fuel tank and another half to the engine block.

The car macam coughing when I started the car. Hahaha.

Btw, if refuel after pouring half, refuel half tank ke full tank?

refuel full, then 1-2days go service......rev hard if can

OK thanks! Let's do this

must do the spray also

My car have a bit of "eat" engine oil, can i still do this?

Don't do it. Go check for the source of leak. If it is losing engine oil slowly, I live with it and top up. If it is losing every very often, better go check. Doing this cleaner will only worsen the leak as it cleans the dirt and carbon that seals those old seals. Are u using conventional or synthetic oil and what is the service interval?

Been using Fully synthetic all the way, 8-10k service interval

Yup I stick with 8000km/6months with fully synthetic. Another scenario I see sometimes is people with high mileage been using conventional the whole time and switch to synthetic and the engine starts burning oil.

Do you have any suggestion how to reduce the burn oil issue? I need to topup the engine oil quite frequently as it leaks and burns EO. I do perak-johor trips every 1 or 2 weeks

whats the cause of burn oil or is it engine oil leak ??
burn oil is worn piston ring

Do you see any external traces of engine oil such as below the car or around the engine bay?

Switching to mineral oil can reduce leaks as it is thicker than synthetic oil. But the only real solution is to overhaul your engine to replace the piston rings and gaskets. If not worth doing just keep topping up.

Use 20/50 oils
