I don't believe in engine flushing too, never do that to the cars that I owned, I even stop the dealer from doing it during warranty period

I took some cylinder head photos of my ex car when I replaced the valve cover gaskets

mileage was 140,000km when I took these photos

I used the cheapo shell helix ultra bought from giant at $29.90 per 5L (some say it's fake oil)

oil change intervals were every 7,500km or 10,000km or 15,000km depending on my mood

you can see how clean are the parts under the valve cover, all are still in bright aluminuim colour

 

close up photo of the cam lobes, the most prone to wear area amongst the parts in cylinder head, they are all smooth and shiny like mirror, no scoring no marks, the blue colour of the cam lobe surface is not due to overheating, it's the reflection of my old samsung phone 😁

I see many Sgcarmart/fb/carousell ads will include engine flushing in their regular engine oil n filter change 

Heard ppl recommending not to do engine flush for cars that have been running for long, as the sludge acts as fillers to protect seals though. 

Does it mean if done when the engine is "young", it's a recommended step to do, as part of the regular eo+filter change steps?

 

If u no bowel problem or constipation, would u suka suka buy a bottle of laxative to drink?

Exactly. Modern synthetic oils has made these snake oil products redundant but yet still got ppl fall for it. Lagi worse, AD upselling these. Margins must be very good

over the years, I have learnt that car consumables (oil, filter, spark plug, brake pads, tire etc) are almost like religions

everyone has their own belief, you won't get an answer after twenty pages of debating 😁

Most important is to change your engine oil regularly.

The protective detergent/additive does wear out and then less protection for the engine.

If you keep doing this, there's little chance of sludge forming. And no need for any flushing. A good working engine oil basically is flushing it all the time when the engine is running.

Also the engine temp must be within operational temp, not too hot and not too cold, to prevent forming of sludge.

For those who modified their engine or cooling system, without knowing what they are doing, then these kind of trouble is self-made.
