Oil sludging issues of 9th generation altis

[solidsnake4747]

Ang sludging ba ay 90-100% na eeliminate kapag nag change oil ka? For example when I checked my oil, makapal na siya masyado at may konteng sludge na sa loob ng engine. If I change my oil now, will all of the sludge be removed meaning that 90-100% good as new na ung oil or meron siyang cumulative effects for the next oil changes?
By "cumulative effects" I mean ung bits of sludge na di natanggal dahil late ako nag oil change dati ay dadami if I don't follow the next regular oil change schedule.

Here is the scenario: Its been 12k kms since I changed the oil. When I checked it, its very thick already and then small amounts of sludge has formed. If i change my oil now, will all of the sludge be removed or is there a special procedure to toatally remove all of the sludge?

Oil sludge is a problem of the current crop of Toyota vehicles. This is the reason why you should religiously oil change every 5,000Km... Do it now bro, before it presents you with bigger problems....

Engine flushing may be considered...

Every 5k kms po ba or every 3 months?

Nalilito kasi ako tol, ang 5k kms ko would last for approximately 1 year, so that means every year ko lang i change ang oil? Pure city driving lang kasi sa akin.

Or dapat every 3 months before reaching 5k kms?

2002 1.8g automatic ung sa akin na sasakyan.

It is every 5,000Km or 3 months, whichever comes first. I surmise that this is the recommendation of Toyota.. (For Honda, it is every 10,000Km or 6 months, whichever comes first)... I do not subscribe to this, though...

may sludge na siguro yan bro. try to have it opened for inspections.

first of all, bakit hinayaan mung tumagal ng 12k km before thinking of getting your oil change. its a basic routine of basic car maintenance.

have your oil change right now. tama si CVT, engine flush might help. but i highly recommend to open the engine top cover and have it physically inspected. dont forget to share pictures!

for me, i am following the 5k km intervals. which i do atleast 3x a year.

but i think, you should be good at 6months intervals, since your car is not as driven frequently as i think. kung taonan ka magchange oil, diba parang inistuck mu lang at binubulok mu yung langis sa makina? may mga shelf life at service life din naman ang mga langis.


btw, as you did not mentioned, how many kilometers you have already? and when was the last time you have your ATF changed.

[hy-n-dry]

isa sa mga causes ng sludge is pag nagbabara na yun pcv (positive crankcase ventilation).. kung sa labas ka nagpapa oil change maigi na pa-check and palinis mo rin kung kaya pa linisin. pag di kasi naaalis yun vapor ng oil sa crankcase eh napaka dumi nun at nagsesettle yun mga halo-halong dumi at di maka labas.. kung barado na pwede palitan..

[roberto_minosa]

Sa ZZ-series engines lang ba nangyayari yan? O pati sa NZ, TR, AZ, at GR?

mga master may prob ako sa altis matic ko san ba makikita yung relay or fuse ng compressor clutch pag on ko ac wlang output na 12v to manetic cluth. patulong mga master baka makaya natin.....salamat!

This month lang sa Toyota mismo ko pina-PMS car ko. Since worry ko din sludging I asked them about it. According to them oil change will not remove the sludge outright but it will little by little just follow the 5km schedule. Kung gusto mo agad agad kelangan daw flushing.

Guys medyo napa-isip lang ako kung kelangan ba yung 3months interval. Sa case ko kasi tumagal ng 7 months nung ma-reach ng car yung 5km interval. Sa service record kasi ng car ko nakatatak next PMS is after 5km ulit. It didn't mention after 5km or 3month whatever comes first. And if you will check the PMS chart of Toyota casa, the schedules are by kilometers and NOT by months/time interval. Please enligthen me.

Kung gusto mong ma condition agad ang iyong makina at maalis ng paunti unti sludge nito sundin mo na lang 3month interval ng change oil para madaling malinis loob ng makina mo.

[meledson]

Maganda sa makina ang madalas na change oil. masakit lang sa bulsa. Iyong 9'th gen namin ay biktima ng sludging. engine over haul, palit cylinder head at madaming parts.

full synthetic ang gamit at nasusunod naman ang pms schedule. now semi synthetic na lang ang gamit ko tapos every 5K km ang palit. good for 7K daw kasi ang semi synthetic.

mineral ay good for 5K pero mas maganda na wag paabutin ng 5K before the change oil.

pag low milage, change oil evey 3 months pag mineral. 6 months kung full synthetic.

[voltscastillo]

is it really sludge or varnish (yung kulay dark brown pag sinilip mo yung mga aparato sa ilalim ng oil cap)?

lots of people sa internet report great de-sludging results using auto-RX (an imported product).

you can try changing oil with higher detergent capability, like a diesel engine oil (hdeo). change it out every 1,000 maybe that would help.

last recourse would be to open the engine and clean out the sludge manually.

[hy-n-dry]

dapat lang alagaan natin PCV ng makina natin.. yan ang cause ng sludging pag nag bara at di makalabas mga gas at contaminants na nasa loob ng crankcase.. even with synthoil walang magawa pag nag accumulate na mga contaminants.. mura lang naman pcv kaya pwede na siguro once a year palit na lang.. meron ko mga nababasa about "oil catch can" na nakakatulong para maiwasan sludge..

I too have a 2005 9th Gen Altis 1.6E A/T with a 75k kms mileage.

Hmmmm....sana wala pa sludging issue toh. Will have the enginge opened to check the internals when its time for the 80k kms PMS.

For 1 year already, I use Shell Helix Plus (Blue) 10w-40 Semi-syn every 5k kms. I got the car 2nd hand from my aunt, she always had her service done at Toyota Makati, and they use Toyota Semi-syn since then.

By the 80k kms PMS, I plan to change to RP 10w-30 Fully-syn after reviewing and asking around for the benefits of using a Fully-syn oil. But if I follow the 10k PMS interval for Fully-syn, will my Altis still encounter the sludging issue?

....of course by the 80k PMS and before switching to RP 10w-30 Fully-syn, I will have all the oil seals checked and replaced if necessary, open the engine to check for sludging, and if there is I will consider and engine flush. Alteast I'd make sure the engine is ready and fit for swtiching to a Fully-syn oil.

^^^ may nakausap akong makaniko dati, its the fully synthetic oil daw ang may sala. so kahit na regular daw ang change oil, possible pa rin na magkaroon ng sludge.

It's not the synthetic per se. It's the long-change interval. Stick to the mineral (or stay Synthetic... doesn't matter) and the 5000k interval and watch your oil carefully for signs of sludging or premature exhaustion.

And check the PCV system. Cheap part to replace if it's worn out, but absolutely vital to the health of your oil.

Thanks for the advise. Yes will have the PCV checked and cleaned over the weekend.

So based on your opinion; going Semi-syn or Fully-syn I should still stick to the 5,000 kms change oil routine?

Actually I am also having 2nd thoughts on doing 10,000 kms change oil even with Fully-syn eh. Kung baga regardless if Fully or Semi-syn, the dirt will still be dirt and will still stay on the oil....so letting it stay there for 10,000 kms is like keeping the dirt in your engine for 10,000 kms.

Did I get it right or is Fully-syn totally able to lessen the usual dirt accumulated by the engine for 5,000 kms up to 10,000 kms compared to using Semy-syn?

Dirt and moisture are part of the problem... but that can be minimized by changing your oil filter every 5000 kms, whether you change the oil or not. The problem with the 10,000 kilometer change is that the fancy long-chain synthetic molecules that synthetic oils use to provide better protection break down over time. How long this takes depends on the engine tolerances and heat.

Now heat is the biggest killer, right there. Our local traffic and hot weather increase the heat stress of the oil by lessening the cooling efficiency of the cooling system. Some people might counter... but how does a 10 degree difference in weather at 30-40 degrees make a difference in an engine running at 100 degrees? Well... where do you think the engine dumps all that heat? If the weather is hotter, the engine has a harder time getting rid of it!

*Oh, this is also why the US and some European countries have much longer oil change intervals than us. Milder weather and less traffic.

Now many newer engines run tighter tolerances and higher temperatures for fuel economy and emissions reasons... but apparently Toyota's engines run pretty borderline hot. Your temperature gauge may not be showing it (since it only shows coolant temperatures), but after 30 minutes in traffic, your oil is suffering, breaking down into its components and losing its ability to protect your engine from wear and tear. And as the molecules break down, sludge starts to form.

So... changing the filter every 5000, helps reduce contaminants. But it won't restore damaged oil. If your miles are only highway miles... no problem, go 10k. But if you drive in traffic, stick with a cheaper oil and do the change every 5k.
