At first I read it I thought u were saying no shit find shit to make

Engine flushing shouldn't be done if ur car isn't experiencing problems from sludge buildups. So far in my life I've only heard 2 cases of engine flushing, one which is done on my friend's mother's car that had went unserviced for 4 years or 35,000 kms, and another one which I've seen myself at the workshop where it was carried out on a Saga 1.3 carburettor engine. Also lady's car.

Conclusion, unless u're a lady who doesn't service ur car at all but drives a lot, flushing is totally unnecessary..

Anyway, I had this funny experience once.. I was at an accessory shop looking for ICE stuffs to plonk into my car.. Then suddenly this lady drove her Myvi out of nowhere right into the shop where they usually park customers' cars to install stuffs.. So out of curiosity, the boss asked the lady if there's anything that he can help or what she wanna install.. She selamba je told the boss she wanna service her car..
...at an accessory shop..

I dont know whether to laugh or pity that lady..

eh but nowdays some accessory shop doing oil change service, or the other way workshop selling accessory....especislly at small twon areas.

Actually from everything I've read and discussed with ppl with these technical backgrounds (I still newbie...),
Conclusion : Never never do engine flush UNLESS you're encountering engine issues that requires it (meaning last resort, no choice).
In lots of cases especially those that have lots of contaminants and sludge, doing flush might makes things worse. Flush will lossen those solid sludge. Where do some of these sludge go since its heavy and doesn't float? When you flush it, it will go thru oil passage, pumps, tubes, drain holes and chances are high these heavy solid will just stuck there.
If you're lucky and don't have much sludge to begin with, you might just make it. As do some of those that have already done flushes.
If any of these sludge do happen to get stuck in just any one of the above places, you're engine will kaput. When that happens, you will have to do a major overhaul....assuming it did not damage your engine enuf, if that happen, new campro CPS coming. Chinese proverb, mou si wan si lei chou meaning creating problem when there is none in the first place.
Another theory include using flush oil. Flush oil are very powerful solvent meant to loosen those sludge. There always will be a couple of % leftover in engine after finish flushing (not 100% will come out). Imagine those mixing with your engine oil and what it will do to your engine long term...go figure.
Excerpt for NBC Los Angeles says it all.
""After engine flushes, there's a pretty high incidence of some damage to the interior of the engine," Chris Martin of Honda tells NBC Los Angeles.
That's why Honda issued a memo to mechanics advising them not to perform engine flushes. Other major car-makers, including Ford, General Motors, and Nissan have all issued similar advisories against the service.
Why? Over time, gummy deposits can build up inside your engine. The chemicals used for engine flush, are supposed to break up those deposits. But car-makers say, pieces of that broken up sediment can clog up other parts of the engine and ruin it."

Then how ????? fully syn no good, semi syn poor, mineral also no good, flush cannot , oil filter cannot last long ..........wat to do for our car should use cooking oil Helang brand, or Bo Bo sesemi oil.......

Those expert always posting the optimistic opinion because their statement are purposely posted to public for viewing, they cannot too bias to either side and they will never come out a conclusion or make promise, in case ppl follow what they said and end up with troble finaly they get shoot up.
