Nothing beats your change your oil earlier . You engine will be super clean . Instead of 10kkm change ,why not change it at 7kkm.

I see..Let me rephrase that bolded part. Instead of the varnish show carbon is developing in the engine, its supposed to be the varnish shows that carbon is not fully cleaned from the engine. There will be accumulation of carbon if it continues.


Hmmm. How do i make it clearer.. varnishes means there were deposits, hence it changes color even on the metal. Means not 100% clean all. Those exposed parts away from hotspots will be ok due to the varnishes cannot get thicker as the oil is still capable. But those super hot and tight spaces, the carbon is baked and it will slowly build up there. Especially at the piston rings lands.
Dont have to take my word for it...research abit on 10k oil change practices and see what they find. There were reports on gunk forming, especially on mostly city drive.

And yes even bold is enough, as long as u dont drive 10k km in city. My car having oil consumption due to previous owner do prolong oil change intervals. Its was over 1L initially. When i got it, i change every 5k km and it slowly improves. Now its consuming around 400-500ml.

Anyway, those varnishes u see on high mileage engine, it can be clean until silver shining back with the valvoline protect.

I agree with gunk forming in tight spaces around piston rings, I use this video as reference :

But this was caused by 10,000 MILES oil change interval, not KM!

As the guy says, change your oil every 5000 MILES (not KM) or 6 months, and you will have no problems

(this advice is for Toyota engines only)

Yeah angmoh land 10000 miles, even toyota reliable engines die fast. And they have stretches and stretches of long roads.

In malaysia roads, i have seen engine rebuilds that changes oil at 10000km and talked to the mechanics. 10000km will have varnishes and some gunk especially if mostly driven on town. I have seen the insides of malaysian's cars engines, hence i always recommend people to change earlier. If wan to use the cars for 9 years or 200k km, i think can just follow the 10k km if written on their manual book.

Btw my friend's vw arteon engine, 3rd year, below
30k mileage already started consuming oil 1L/5000km. And its normal on these engines too. 10000km oil change intervals. And VW says its normal to consume oil lol. Many having these issues until its already the norm. Confirm not engine cylinder walls worn as its using low tension piston rings. Those rings confirm stuck by carbon. Even with just abit of carbon it will get those low tension rings stuck easily. This is the proof of carbon forming at the pistons with 10000km in malaysia. Normal piston rings will be able to retain its function longer.

The fake oil are true here hence i will buy only from shopee mall seller.

Kinda disagree. Most car with using fully synthetic no issues to take it till 10k km interval, hnece most Japanese brand put it at there. Conti brand with a more environment conscious thing, make it till 15k km interval (by using fully synthetic), also no issue.

Had car with 380k km with 10k-13k km service intervals, no issues. Just make sure if got oil diminished after sometimes, it must be due to leak somewhere, like valve cover gasket or major at flywheel oil seal. Repair that, then no problem in a long run

Be it a Honda, better send for flywheel oil seal check considering high mileage. Mine kene at 230k km, and change together all the seal one go. Burn almost rm1.6k at my regular workshop. Ask TikTok workshop, straight quoted rm3k+ all in free engine oil

Yeah bro same like u OCd EO short intervals, my new cars even during warranty I go in between outside SC oil change every 3 mths

Can share shop name?

Amsoil is the bestest

rm98 for 946 ml
need 5 bottles

TS' engine probably full of debris from using too much recycled crap that now need to stick back to expensive EO in hopes of restoration.

Not all will have issues, but more issues with 10k km. If cars with low tension piston rings, 100k km already almost all facing eating engine oil.
Lots of issues, maybe u are not aware. Go to vw, bmw, audi group and check out. Oil consumption has become a 'non issue' because its already considered 'normal'.
My friend's vw arteon 3 years old, 30k+ km, 10k oil change intervals. Already consuming engine oil.

Wrong. Its improving in my hand.
Fact is previous owner didnt take care much and its consuming engine oil at more than 1L/5000km.
When i got it, i change engine oil every 5000km. Now its only consuming 400-500ml/5000km.

Weiiii dont laaaaa

Some how H with 1.5t will have increase due to slight dilution oil
My ketam run 144k km no drop at all
Now G10 115k also no drop

There is only 1 seller selling valvoline restore and protect in shopee.i bought it from him.
