Sir, yung castrol gtx ba ay synthetic??? Hindi, non-synthetic yung Castrol GTX Diesel. Sabi ng iba't-ibang studies, walang gaanong diperensiya ang Synthetic at Petroleum based na engine oil. Nagkakatalo lang ito kapag ang engine ay di laging napapalitan ng oil dahil sa ang synthetic ay may properties na mas naka-suspend ang mga unwanted combustion particles kumpara sa petroleum based oil, saka matagal bago mag-build up ng sludge sa loob ng engine ang synthetic dahil sa mas mainit ang tolerance nito sa heat. Kaya ang bottom line ng regular engine oil -vs- synthetic ay kung ang pagbabasehan din lang e ang frequent oil change na 5000 km, walang diperensiya sa performance ang synthetic -vs- petroleum based engine oil kung hindi ang presyo.

I have talked to a motor oil distributor today inquiring about acea c3 specifiction. He told me as of now they have no stocks.Acea c3 is good for our cataylyzed prarticulate filter(cpf) because of low sap(sulphur, ash, phosphate). the oil we are using the Petron ci/sl spec. might destroy our cpf.in the long run. Therefore we should ask columbia auto corp. is petron the right oil or else they should replace our cpf in case something went wrong. Because of the malfunction of cpf, it might destroy our engine. Can someone from CAC make a clarification.

Palagay ko masyado nating binibigyan ng pansin ang CEA rating ng motor oil dito sa Pilipinas. Ang CPF ng sasakyan natin ay para sa "Emmission Control" at para palinisin ang lumalabas na exhaust sa ating engine combustion. Ang CPF or "Catalyzed Particulate Filter" ang sumasala sa mga pollutants para di ito makadumi ng ating environment.
Ang role ng CEA rating sa oil na ginagamit natin ay para makasiguro na mababa ang mga "pollutant" contents nito na katulad ng sulphur, etc. Dahil kapag di natin sinunod ang specifications ng ating engine oil, e mahihirapang linisin ng CPF ang ating exhaust.
Pero dahil nga sa mahal at karaniwan e wala ang ganitong oil dito sa Pinas, di naman ibig sabihin e katapusan na natin ito. Ang kailangan lang nating gawin e "pabugahin" natin ang ating Carens (diesel or gasoline) sa highway paminsan-minsan at patakbuhin ng equivalent ng 70MPH (mga 120kph yata ito..wala kasi akong speed-converter dito) para mag-init nag husto ang ating catalytic converter at masunog ang mga particulates na naiipon dito.
Dati-rati walang catalytic converter ang mga diesel, maliban na lang sa mga Mercedes Benz. Sige lang ng buga ng maitim na usok ang mga sasakyan (dito sa Pinas). Ngayon iba na, kasi para mapatakbo ang mga diesel engine sa Western countries e kinakailangang lagyan ng CPF at maging responsable sila sa environment.

I dont think by accelerating at about 70 mph (120kph) will clean the cpf, it will only clean the muffler. Just like our air cleaner, it will clogged after long use. The cpf uses catalytic substance with the fuel to burn the soot when it reaches certain temperature.When the filter clogged because of SAP(sulfur, ash and phosporous), it will deteriorate and affect our engine and fuel consumnption. It is bad for our engine running out of diesel, it will destroy the cpf. I wonder how much will CAC charge us for the cpf and do they have ready stock.

It is better to play safe using the right motor oil than to regret later. Especially the cpf, its new to us. When it malfunction, all kia carens will be a smoke belcher. I dont know how much it will cost , sana d taga ang price.

I dont know how much it will cost , sana d taga ang price. Here's some excerpts from an article on CPF (CDPF for diesel engines) Quote: "Long term durability is the most important issue with catalyzed particulate filters, especially in the fully passive configuration. Since filter regeneration depends on the duty cycle, it is very difficult, if not impossible, to ensure failure free operation under all possible operating conditions and duty cycles. Even on hot engines, a single period of extended idling can lead to overloading of the filter with soot, followed by an uncontrolled regeneration and catastrophic failure.Proper engine maintenance is also of critical importance in assuring long filter life. In particular, filter catalysts are typically sensitive to poisoning by lubricating oil and its additives. CDPF equipped engines must be well maintained to avoid excessive oil consumption. Engine failures resulting in oil leaks to the exhaust system may result in immediate deactivation of the filter catalyst. Ash Accumulation. Another source of increased maintenance in CDPF-equipped engines—pertinent to both retrofit and OEM applications—is related to ash emissions. Just like other types of filter systems, CDPFs retain most of metal oxide ash emissions which are generated (primarily) from lube oil additives. Since ashes are incombustible, their accumulation causes steady increase of the filter pressure drop. This problem may be alleviated by periodic cleaning of the filter using water, compressed air, steam, or other means (cleaning operations should conform to the manufacturers’ recommendations to avoid any detrimental effect to the catalyst).

It is bad for our engine running out of diesel, it will destroy the cpf. I wonder how much will CAC charge us for the cpf and do they have ready stock. The CPF is designed to "regenerate" (clean) itself once it is clogged with soot (mainly from high sulphur content of the diesel fuel used). The only contaminants that the CPF won't burn is ASH from oil additives. In many CPF, the filter is opened and cleaned manually every so many thousands of km/miles. I don't know if ours is designed this way. Yes, driving the Carens at higher highway speeds DO BURN the contaminants in the CPF filter. Prolonged short-driving and city driving kills our CPF because of constant engine idling while waiting for traffic to go. The design of the CPF to heat up and burn the contaminants is what particle filtration is all about. The CPF is "like" an air filter but unlike the air filter, this is designed to heat up and burn particles. Anyway, I do agree with you, however, that the proper oil specification is the best oil to use for our Carens. But in the absence of this type of oil, it is better for owners to understand what the CPF is all about and that EXCESSIVE IDLING kills our CPF more than anything else.

Thanks, Jching now we understand the function of cpf in our carens. Now we should compel CAC to use the right motor oil. Or else if the cpf breakdown or malfunction , CAC should take the responsibility to replace the cpf.

i asked columbian and congressional avenue dealership regarding our query about the oil they are using (ACEA C3), they said that it has been pre-blended by petron and tested by KIA to conform with the specs of the carens.
regarding the acea c3 specs, i was also told that this specification was given particularly in regions with cold temperatures. unlike in our country, the kia oil they are pouring in our engine are designed for tropical climate. If you will notice, the viscosity index of oils with acea c3 specs are 5w-30, which is designed to withstand and not freeze in low temperature.
somehow, the answer given to me by the technician was satisfying and calming. hopefully our carens will not turn into smoke machines in the future.
hope this piece would somehow give us some peace of mind. the kia oil is in white plastic container,not in drums. its cheaper than helix, castrol or petron.
