Semi oil used to have shorter mileage.....but now semi also being pushed to 10k km before oil change which makes me very uncomfortable .

Last i know semi oil maximum it can go was 7k km some recommended 5k km for semi oil if you love your engine.

for me.....i'll always use fully and do an oil change 1k km early.

Nope. Experienced mechanics will give you advice & solutions you based on what is visible and not from what is invisible. Visible means leaks. Invisible means nothing worn can be seen now, but is seen later caused by maintenance products such as Seafoam.

I get the part where you need to drain, fill, drain and fill again the engine oil. What I don't get is, why with seafoam can drive for one week (I know for giving time to clean, this part I get it) but once you remove it, and refill with cheapo oil, why only run 20 mins so short, instead of running maybe 1 day to clear things out.

Erm, thing is it's still using the old oil filter, I don't know what's the effect of after flush still using an old oil filter with new oil.

When I did my flush my car just left there for idle for 15min, no revving at all. Sacrificial oil came out tea colour.

I guess running a day wouldn't hurt

Noted on filter.
But isn't the oil with seafoam more dirty? So it baffled me, why that one for 1 week but sacrificial oil so scary just 15 mins. Haha.

BTW, just a discussion.

Up to you if you want to go workshop twice to change oil.

My point is that if your mileage is very high one oil change isn't enough to clean it.
New oil added in simply turn into 3month old in 15min.

They'll ask ppl not to go ahead with engine flush because might cause leaks.
besides the flush, the intake cleaner also they dont do unless ppl requested them to clean throttle body.
for car jerking at idling, usually ppl will replace a whole lot of things like spark plugs and other things like (most mech buat bodo to earn more money). just service can solve problem but ended up changing 3-5 parts.

one day when things fail, they just tell you to overhaul everything.
like one of my friend's car the water temperature keeps on going high. cant solve it.
mechanic ask him to overhaul

Everything has a lifespan i'd rather make my car feel new.
if gasket really fail, then one shot change the whole engine gasket.

Thats the thing. 99% people buys cars and expects the cars to live forever. Why do you think newer cars has lesser and lesser self serviceable parts in it? Some newer cars does not even have a dip stick or even oil filler cap. Everything is passed on to electronic sensors. Also lifetime engine oils. (This exists in USA, but i do not know if any other countries has them yet).

In the end the consumer wants maintenance free cars. Car makers made this their advantage in making the cars buy, use and throw away. Much like Apple products.

To be fair, if your car is only 5-7 years old and you did seafoam or any other type of decarbonizing, cleaning, flushing. That would be fine. Thats the max rate the vehicle life would be at at normal day to day use. But some are being abused. Those are the ones that cause problems.

In fact if a modern engine burns oil (Any engine that uses 0 to 30 grade oil now), you can't go 40 grade or higher like you could with older engines. It would kill the engine cam switching and adjustment features due to the incorrect oil pressure flow needed to make those work.

Whatever the case, everyone should change engine oil at schedule and at least every year, pump a tankful of the the most premium fuel they can buy and do an Italian tune up.

those complain leakages after flushing should be those ppl who never had gaskets changed before.
gasket if can last 8years already strike lottery.

i'm from mechatronics background so i can pick up car knowledge fast, the conclusion i get is that the normal ppl here is they dont know nuts.
- try to outrun the service intervals, pushing their luck (hey i did it too)
- most of the money get chopped by mechanics (including me, gf car compressor failed (should be 500-600), ended up charging rm2,000 including the inner coil, MCB shop boycott him d)
- blindly follow/believe manufacturer marketing, blur blur (DSG gearbox, start-stop BS)

so now, i read whatever i could, at least i could troubleshoot and estimate the problem beforehand.

dont think revving can burn the carbon at throttle body btw.

130,000km oil with Seafoam engine treatment and Seafoam spray
this one no sacrificial oil. put in new Shell full synthetic oil
the car now press a bit of oil can move smoothly, previously running at 100kmh engine sound was super rough. now not so rough





-------------------------------------------------------------------------------------------------------------------------------------------------

my other car with 80,000km mileage. (just run flush for 20min)

consulted my friend (the one with 200,000km on it) what thing he use to service the car cuz his one tank can go 700km. mine only 550km.

so conclusion is a lot of things (my engine should be super dirty with oil deposits, so the whole car is not responsive, and not so fuel efficient)
this service interval i switched to Liqui Moly full synthetic + engine flush + additive (to reduce friction)

this is what i did with it, first spray Seafoam valve cleaner into intake and rev everything to clear valve.
then drive to workshop to ask them do engine flushing.

OLD engine oil (7000km) after adding flush and running it for 10minutes. like KOPI-O



then because i watched some videos that do flushing on cars that never done it before (run 100,000km never flush) they had to flush - drain - add new cheapo oil to run 2nd round (run 10-15min) then drain. THEN only add in LIQUI MOLY.
Basically DRAIN THE OIL TWICE if not the new oil added will be instantly dirty !!

this is the sacrificial cheapo 4L engine oil (new engine oil just run for 10min) that i added in after draining the oil.
pour new oil in immediately turn dark, dirty like teh O.

LOL. Thanks Bro. How much the workshop charge you when you do twice? And how much for once?

Just wondering. Im thinking to do this for my now 110K km car on Jan. But first have to get to ace hardware first.

BTW come to think of it i think I did engine flush once. I think last year the workshop guy was asking me on about engine flush and the bottle cost about RM20. What he did is poor it in to the old engine oil. Run car for 10 mins and remove the oil. That's it.

Anyway. I memang plan to use seafoam.

i brought my own oil la. they charge rm 50 for labour to change twice.


one way of testing before/after is when u press pedal a little bit.

try feel how your car respond before adding anything.
the pull will only come in lagging behind or press down pedal a lot only can pull.
but after treatment the pull will be instant

I didn't use seafoam spray, but threebond engine conditioner.
Same concept, spray through the throttle body, heatsoak it and wait 15 minutes and then start the engine.

Picture of my head intake side


That is the result but, this was taken after 15k KM after the treatment.
I guess the engine itself could been clean to start with or my driving style is rather agressive. (Lots of short burst accleration and high rev)

Just doing the seafoam spray or similar treatment.
I definetly felt a difference for cars that are high mileage (5 years or 100k KM and above)
Mine saga blm (135k KM when done), I felt FC a bit better. Rest felt the same, could be it that my engine was at it optimum to start with.
My friend neo (160k KM, when done), roughness at idle felt smoother but somehow the exhaust was a bit more alive.
Lastly, my friend myvi (130k KM, when done), sharper respond and better idling quality.

I would like to just do the seafoam in the engine and see how well does it contribute.
But it seem costly to do it; seafoam, engine oil for flushing, 2x proton oil filter and engine oil that i usually use which is molygen 5w-40.

wow your valve is spanking brand new. i guess those high mileage that never did any flushing or throttle body cleaning will feel the difference the most.

regarding the sacrificial oil, it's just something extra if your car havent flush before for 100,000km.
a lot of ppl will just flush and thats it, but thats the fact your new oil gonna look like "tea" in 20minutes because there are too much shit inside there that cant be clean with one round of oil change.


the intake spray will make the throttle response better (car felt like hesitant to pull before), while the flush will make the engine spin with less resistance, therefore car will coast further, car feels lighter.

if those cars use semi-syn oil, probably build up sludge even faster due to viscosity.

like brand new. haha. remember is 155k KM and 15k KM after "decarbon"

for me the only that worries me, is seafoam adding to engine oil.
it can be added in petrol tank, before oil change and after oil change, and decarbonize valve and piston.
is a bit intriguting how one oil/additive/treament can do so much.
have you tried putting it after oil change?

one is liquid and the other one is spray

liquid is added to engine service hole and add into fuel tanks help to clean injectors too.

havent tried put in after oil change. but after i added into the car, already can feel the difference and after a week the pull is not that strong, dunno is change different petrol factor or not.
so best is to change oil in a few days after adding because it will dislodge a lot of sludge in the engine that needs to be drained.

if u watch that farm guy video, he said seafoam did not make the engine oil thin.
and yes he did drain 2nd time and the oil was black as well.

personally, to gain back the power of your car engine just like new again, just take your car for long distance drive and rev it to redline for prolong of time.

This action will perform the "decarbonise" in the engine part, and reset the ECU of the behaviour driving as well. Then your engine will be clean and as powerful as new again.

Just my cent, I maybe wrong.

Anyone tried mixing the sea foam with engine oil that's been drained and collected in container?

If it turns to kopi, that means.....

yeah, this is good idea

why would u want to do that ?
