flushing additives just strip off all the seasoned in oil film oil areas , each time metal to metal again

sounds stupid

Thanks for the suggestions. Will look into those suggested oil. For now, I am going to use same viscosity 0w20 fully synthetic Bold or Mizu oil as the cheap oil.

Oh, if viscosity is a concern, then these HDEOs might not meet your purpose, coz they are usually SAE 15W40

Later give ur review for Mizu 0w20. Currently on Honda 0w20, great oil but once reached 7k km per interval, it start feeling like some weight on the engine. Even from new and services it at sc.

just to confirm it is fully synthetic right?
if yes then maybe let service centre check obd stats on the oxy sensor , MAF and throttlebody

It's not as bad as you think. I have had my old car send to SC for 8 years. Each time they will do the engine flush. Engine was still quiet the day I sold it. First buyer saw the car and bought immediately.

What about your horror story in using engine flush? Mind sharing?

which brand is that? afaik honda sc won't allow for flushing even they sell the flushing oil. u add that they will put a remark on the invoice saying customer demand for flushing

It's exactly Honda. And they always ask if want to do the flushing. Maybe new SOP they don't do anymore but that time they will happily do for you.

I never used it, because checking the contents , they are solvents , which does at it says dissolves everything, places should dissolve and places shouldn't dissolve

Just regular oil change with good oil is enough to make engine last looongggg time, just looks at new car warranties with all these tiny turbo engines pushed to max, no qualms offering you 5 years warranty as long oil changed according manual.

same practice but my concern was if put the flushing oil, how to ensure it removes 100% from the engine? Old Oil threw out either using a sucking airpower machine or opening the bolt below the engine. my mind saying that the air sucking suck all oil better than gravity oil out from the bottom bolt.

More oomph HDEO (diesel) id recommend caltex delo 400/delo gold, or mobil delvac mx, but u can use those u recommended as well. Should have an older API Sx standard. Good enough for flushing as diesel oil clean better.

Is your honda using R20A3 engine? (Old Accord)
User manual says Xw30, SC uses Xw20......

Using the right oil & filter, and change within the recommended interval (5k mineral, 7k semi, 10k full)

2.4 2015, Earthdream engine. Manual mentioned 0w20

Different engine......but thanks for sharing

I myself use Duron hehe...

that's another good point, the flushing solvent will never be removed fully, just contaminating the new oil again

Which type of HDEO should we look for when using it for flushing purposes? Any required API spec?
Would it matter to pick either semi synth or fully synth?

Basically affordable HDEO from name brand oil mfg ok liao. 18L tub delo400 only around rm209 direct from distributor
