oh.... actually ICE also no need servicing one! no wonder all petrol kiosk got sell 1L pack engine oil! 

I was joking lah

there will be sediments at the bottom of the oil pan that cannot be burnt away

can only cleared by draining the old oil

I remember last time,a W124 Mercedes Benz Gearbox,never change ATF before,Car driving okay,the 2nd Owner,bought it & went Flushing,Car Gearbox "Slip" when just drive out Workshop...later Gearbox need to Overhaul.

actually this "phenomenon" happened to me too 😁

car aircon no problem but seeing 80k and doing major service, opted for aircon flush.

after that, the coldness worsened. ac still working but not as cold or strong as previous.

Still working better than the Cooling Coil puncture...then need to change..so many cases..after Aircon Flushing..Coil gone..because high Pressure cause the Old Coil to burst.

There is only 1 explanation. 

Either your ws that flush your AC didn't follow the book. They pump too low or too high PSI for your ac.

Or they follow according and pump the correct PSI.

which mean if u have top up AC gas before elsewhere.

Before they flush the AC. Your AC system is already running on higher PSI then standard recommended,  which is why u feel super freezing cold.

But now its just cold

more likely didnt follow the book. my car is first hand so ac stock never touched so i assume PSI shd b factory. 

but these days many ws simply just increase scope of services to get more revenue. not all mec are properly trained or hand over to properly operate an equipm. from a ws friend, he say mec turnover is very high now. so end up on job training mec also no choice have to take else no manpower. big name ws included.

I did a quick calculations 😁

if you change the engine oil 3 times in succession,  you will reduce the old oil ratio to 9%

if you change 6 times in succession,  that will bring down the old oil ratio to 0.8%

You are a savior!! Your calculation gave us new breathe.  
Nice.
