According to "Lubes and Grease World Base Stock Guide" and "ICIS", there is a significant increase in demand for API Group III base oil.... Engine oil blended from Group III base oil is marketed as synthetic in many markets....


The increase in demand is driven by:
1) The standard of engine oil is getting higher and it is getting tougher for engine oil made from mineral base oil (API Group I) to get approved. These standards includes API, JASO, ACEA, ILSAC and etc

2) Global car manufacturers are demanding higher standard of engine oil to be used as factory and service filled due to increasing oil stress. Engine is getting smaller in displacement and getting more powerful.... Generally, Japanese car makers would refer to ILSAC, European car makers will refer to ACEA and their own standards such as MB p229.31/229.51, BMW LL04, VW504.00/507.00, RN 720 and etc, American car makers would refer to API, ILSAC and their own standards such as Ford WSS-M2C946A, GM Dexos 1 and 2.... GM had literally stated that only synthetic oil can be qualified to apply for approval of Dexos...

This is technological advancement of lubricant and automotive engineering, sooner or later, all car manufacturers will specify synthetic oil only...

Caltex Delo 400 is formulated with ISOSYN base oil....

http://www.caltex.com/my/products-and-serv...ubricants/delo/

What is ISOSYN?

The iso-syn method you referred to is the patented refining process that is used by Chevron (Caltex) to produce its base oils. This process is a hydrocracking process that consists of the following steps

The first step in this process is atmospheric and
vacuum distillation.

The second step in the process is severe
Hydrocracking to remove the majority of
sulfur, nitrogen and polar compounds and
saturate most of the aromatic and naphthenic
compounds that may be present.

The next step is Hydroisomerization which
is also known as Isodewaxing.

The Isodewaxing process which is patented by
Chevron takes n-paraffins and other molecules
with waxy side chains and converts them
into isomerized branched paraffinic
molecules (isoparaffins).

The Isodewaxing process can also use wax produced
by solvent dewaxing as one of its feedstocks.

The third step is severe hydrofinishing which is
used to remove any remaining sulfur,
nitrogen, polar compounds and unsaturated
molecules.

The final step is atmospheric and vacuum distillation to produce the desired viscosity grades.

This process produces Group III UCBO base oils
that have viscosity indexes ranging from 120 to
over 140.

API Group III base oil is generally marketed as Synthetic....

Caltex Delo 400 might not be blended with 100% ISOSYN base oil but it is definitely not full Group I mineral oil, I would say it should be categorized as at least Semi -Synthetic....

It is not Group I conventional mineral, right?

You said you were looking for Torco or Liqui-Moly, but you also want someone to recommend engine oil.....

Bro, I am sorry, I don't quite understand....

Do you want people to recommend other brand or specific model/grade of Torco or Liqui-Moly?

Synthetic or not, I am not quite sure, Sarjan would need to clarify on that...

From what I know, Petro Canada makes gear lubes with a more stringent requirement than API GL-5, which is known as MACK GO-J and MACK GO J PLUS specifications....

MACK GO-J: designed to deliver 400,000km/2 years oil drain interval and satisfactory gear shifting after 65,000 cycles.

MACK GO-J PLUS: designed to deliver 800,000km/3 years oil drain interval and satisfactory gear shifting after 97,500 cycles.

I guess this is why Sarjan said that it can last so long....

Thanks for the info...

It is known as oil consumption / evaporation, it is quite normal..... but a good quality engine oil will evaporate less than a lower quality one...

Just to share.....







Top pic shows the flashpoint of a typical Shell HX-7 Semi Synthetic 10W40

Bottom pic shows the flashponit of Bardahl 2 oil treatment / additive

Even though oil treatment, such as Bardahl 2
1) increase Viscosity Index
2) increase viscosity
3) improves anti wear properties....

It will lower the resultant flashpoint of the engine oil and make it more volatile....

When you start to have concern for car, you will start to learn more about cars

It depends on individual and his/her love for the cars.....

Proton, Vios or Kancil, it is still car they love....

I love my car, too, even though it is not Porsche....

People's car, people's love and people's money... ....so no comment...

Comparing with many brands in the market, Mobil 1 EP is undoubtedly a very good quality engine oil which is API SN, ILSAC GF-5, GM Dexos1 and Honda HTO-06 approved..... However, if the HTHS and SAPS value can be increased a little bit more, it would be much better engine oil...

Perodua specifies SAE 5w30 for Myvi (old and new)...

Do you mean that Engine Up has already got approval from API? Are you sure?

Thanks for sharing, I am just curious that Engine Up has got approval from API, I thought your know something about this, thats all...hehehe

I have to say that Mobil 1 EP 5w30 is a good oil, in fact it is a very very good oil.... But it is definitely not the best among the oil that I have tried so far...

Unlike Campro CPS, Campro IAFM is running on flat tappet instead of roller tappet... I would suggest you use oil that has SAPS value above 0.9...

I don't have the technical authority to say you can't use... It is just my personal opinion...
